* This file contains an example of a Linear "OpMode".
* An OpMode is a 'program' that runs in either the autonomous or the teleop period of an FTC match.
* The names of OpModes appear on the menu of the FTC Driver Station.
* When a selection is made from the menu, the corresponding OpMode is executed.
*
* This particular OpMode illustrates driving a 4-motor Omni-Directional (or Holonomic) robot.
* This code will work with either a Mecanum-Drive or an X-Drive train.
* Both of these drives are illustrated at https://gm0.org/en/latest/docs/robot-design/drivetrains/holonomic.html
* Note that a Mecanum drive must display an X roller-pattern when viewed from above.
*
* Also note that it is critical to set the correct rotation direction for each motor. See details below.
*
* Holonomic drives provide the ability for the robot to move in three axes (directions) simultaneously.
* Each motion axis is controlled by one Joystick axis.
*
* 1) Axial: Driving forward and backward Left-joystick Forward/Backward
* 2) Lateral: Strafing right and left Left-joystick Right and Left
* 3) Yaw: Rotating Clockwise and counter clockwise Right-joystick Right and Left
*
* This code is written assuming that the right-side motors need to be reversed for the robot to drive forward.
* When you first test your robot, if it moves backward when you push the left stick forward, then you must flip
* the direction of all 4 motors (see code below).
*
* Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
* Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list

*
* In this sample, any visible tag ID will be detected and displayed, but only tags that are included in the default

* the current Season's AprilTags and a small set of "test Tags" in the high number range.
*
* When an AprilTag in the TagLibrary is detected, the SDK provides location and orientation of the tag, relative to the camera.
* This information is provided in the "ftcPose" member of the returned "detection", and is explained in the ftc-docs page linked below.
* https://ftc-docs.firstinspires.org/apriltag-detection-values
*
* To experiment with using AprilTags to navigate, try out these two driving samples:
* RobotAutoDriveToAprilTagOmni and RobotAutoDriveToAprilTagTank
*
* There are many "default" VisionPortal and AprilTag configuration parameters that may be overridden if desired.

* The goal is to determine the smallest (shortest) Exposure value that still provides reliable Tag Detection.
* Starting with the minimum Exposure and maximum Gain, the exposure is slowly increased until the Tag is
* detected reliably from the likely operational distance.
*
*
* The best way to run this optimization is to view the camera preview screen while changing the exposure and gains.
*
* To do this, you need to view the RobotController screen directly (not from Driver Station)
* This can be done directly from a RC phone screen (if you are using an external Webcam), but for a Control Hub you must either plug an
* HDMI monitor into the Control Hub HDMI port, or use an external viewer program like ScrCpy (https://scrcpy.org/)
*
* Use Android Studio to Copy this Class, and Paste it into the TeamCode/src/main/java/org/firstinspires/ftc/teamcode folder.
* Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list.

* goes beyond simply showing how to interface to the IMU.<br>
* For a minimal example of interfacing to an IMU, please see the SensorIMUOrthogonal or SensorIMUNonOrthogonal sample OpModes.
*
* This OpMode enables you to re-specify the Hub Mounting orientation dynamically by using gamepad controls.
* While doing so, the sample will display how Pitch, Roll and Yaw angles change as the hub is moved.
*
* The gamepad controls let you change the two parameters that specify how the Control/Expansion Hub is mounted. <br>
* The first parameter specifies which direction the printed logo on the Hub is pointing. <br>
* The second parameter specifies which direction the USB connector on the Hub is pointing. <br>
* All directions are relative to the robot, and left/right is as viewed from behind the robot.
*
* How will you know if you have chosen the correct Orientation? With the correct orientation
* parameters selected, pitch/roll/yaw should act as follows:
*
* Pitch value should INCREASE as the robot is tipped UP at the front. (Rotation about X) <br>
* Roll value should INCREASE as the robot is tipped UP at the left side. (Rotation about Y) <br>
* Yaw value should INCREASE as the robot is rotated Counter Clockwise. (Rotation about Z) <br>
*
* The Yaw can be reset (to zero) by pressing the Y button on the gamepad (Triangle on a PS4 controller)
*
* The rotational velocities should follow the change in corresponding axes.

/*
* This OpMode illustrates using the rumble feature of many gamepads.
*
* Note: Some gamepads "rumble" better than others.
* The Xbox & PS4 have a left (rumble1) and right (rumble2) rumble motor.
* These two gamepads have two distinct rumble modes: Large on the left, and small on the right
* The Etpark gamepad may only respond to rumble1, and may only run at full power.
* The Logitech F310 gamepad does not have *any* rumble ability.
*
* Moral: You should use this sample to experiment with your specific gamepads to explore their rumble features.
*
* The rumble motors are accessed through the standard gamepad1 and gamepad2 objects.
* Several new methods were added to the Gamepad class in FTC SDK Rev 7
* The key methods are as follows:
*
* .rumble(double rumble1, double rumble2, int durationMs)
* This method sets the rumble power of both motors for a specific time duration.
* Both rumble arguments are motor-power levels in the 0.0 to 1.0 range.
* durationMs is the desired length of the rumble action in milliseconds.
* This method returns immediately.
* Note:
* Use a durationMs of Gamepad.RUMBLE_DURATION_CONTINUOUS to provide a continuous rumble
* Use a power of 0, or duration of 0 to stop a rumble.
*
* .rumbleBlips(int count) allows an easy way to signal the driver with a series of rumble blips.
* Just specify how many blips you want.
* This method returns immediately.
*
* .runRumbleEffect(customRumbleEffect) allows you to run a custom rumble sequence that you have
* built using the Gamepad.RumbleEffect.Builder()
* A "custom effect" is a sequence of steps, where each step can rumble any of the
* rumble motors for a specific period at a specific power level.
* The Custom Effect will play as the (un-blocked) OpMode continues to run
*
* .isRumbling() returns true if there is a rumble effect in progress.
* Use this call to prevent stepping on a current rumble.
*
* .stopRumble() Stop any ongoing rumble or custom rumble effect.
*
* .rumble(int durationMs) Full power rumble for fixed duration.
*
* Note: Whenever a new Rumble command is issued, any currently executing rumble action will
* be truncated, and the new action started immediately. Take these precautions:
* 1) Do Not SPAM the rumble motors by issuing rapid fire commands
* 2) Multiple sources for rumble commands must coordinate to avoid tromping on each other.
*
* This can be achieved several possible ways:
* 1) Only having one source for rumble actions
* 2) Issuing rumble commands on transitions, rather than states.
* e.g. The moment a touch sensor is pressed, rather than the entire time it is being pressed.
* 3) Scheduling rumble commands based on timed events. e.g. 10 seconds prior to endgame
* 4) Rumble on non-overlapping mechanical actions. e.g. arm fully-extended or fully-retracted.
* 5) Use isRumbling() to hold off on a new rumble if one is already in progress.
*
* The examples shown here are representstive of how to invoke a gamepad rumble.
* It is assumed that these will be modified to suit the specific robot and team strategy needs.
*
* ######## Read the telemetry display on the Driver Station Screen for instructions. ######
*
* Ex 1) This example shows a) how to create a custom rumble effect, and then b) how to trigger it based
* on game time. One use for this might be to alert the driver that half-time or End-game is approaching.
*
* Ex 2) This example shows tying the rumble power to a changing sensor value.
* In this case it is the Gamepad trigger, but it could be any sensor output scaled to the 0-1 range.
* Since it takes over the rumble motors, it is only performed when the Left Bumper is pressed.
* Note that this approach MUST include a way to turn OFF the rumble when the button is released.
*
* Ex 3) This example shows a simple way to trigger a 3-blip sequence. In this case it is
* triggered by the gamepad A (Cross) button, but it could be any sensor, like a touch or light sensor.
* Note that this code ensures that it only rumbles once when the input goes true.
*
* Ex 4) This example shows how to trigger a single rumble when an input value gets over a certain value.
* In this case it is reading the Right Trigger, but it could be any variable sensor, like a
* range sensor, or position sensor. The code needs to ensure that it is only triggered once, so
* it waits till the sensor drops back below the threshold before it can trigger again.
*
* Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
* Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list.

/*
* This OpMode illustrates how to use the Expansion Hub's Bulk-Read feature to speed up control cycle times.
* In this example there are 4 motors that need their encoder positions, and velocities read.
* The sample is written to work with one or two expansion hubs, with no assumption as to where the motors are located.
*
* Three scenarios are tested:
* Cache Mode = OFF This is the normal default, where no cache is used, and every read produces a discrete transaction with
* an expansion hub, which is the slowest approach, but guarentees that the value is as fresh (recent) as possible..
*
* Cache Mode = AUTO This mode will attempt to minimize the number of discrete read commands, by performing bulk-reads
* and then returning values that have been cached. The cache is updated automatically whenever any specific encoder is re-read.
* This mode will always return new data, but it may perform more bulk-reads than absolutely required.
* Extra reads will be performed if multiple encoder/velocity reads are performed on the same encoder in one control cycle.
* This mode is a good compromise between the OFF and MANUAL modes.
* Note: If there are significant user-program delays between encoder reads, the cached value may not be fresh (recent).
* You can issue a clearBulkCache() call at any time force a fresh bulk-read on the next encoder read.
*
* Cache Mode = MANUAL This mode requires the user's code to determine the best time to clear the cached bulk-read data.
* Well organized code will reset the cache once at the beginning of the control cycle, and then immediately read and store all the encoder values.
* This approach will produce the shortest cycle times, but it does require the user to manually clear the cache.
* Since NO automatic Bulk-Reads are performed, neglecting to clear the bulk cache will result in the same values being returned
* each time an encoder read is performed.
*
* -------------------------------------
*
* General tip to speed up your control cycles:
*
* No matter what method you use to read encoders and other inputs, you should try to
* avoid reading the same encoder input multiple times around a control loop.
* Under normal conditions, this will slow down the control loop.
* The preferred method is to read all the required inputs ONCE at the beginning of the loop,
* and save the values in variable that can be used by other parts of the control code.
*
* eg: if you are sending encoder positions to your telemetry display, putting a getCurrentPosition()
* call in the telemetry statement will force the code to go and get another copy which will take time.
* It's much better read the position into a variable once, and use that variable for control AND display.
* Reading saved variables takes no time at all.
*
* Once you put all your sensor reads at the beginning of the control cycle, it's very easy to use
* the bulk-read AUTO mode to streamline your cycle timing.

* -- There is a link called "sounds" on the right hand side of the color bar on the BLOCKS page that can be used to send sound files to this folder by default.
* Or you can use Windows File Manager, or ADB to transfer the sound files
*
* To get full use of THIS sample, you will need to copy two sound file called silver.wav and gold.wav to /FIRST/blocks/sounds on the RC phone.
* They can be located here:
* https://github.com/ftctechnh/ftc_app/tree/master/FtcRobotController/src/main/res/raw/gold.wav

* This OpMode illustrates how to use a video source (camera) to locate specifically colored regions.
* This sample is targeted towards circular blobs. To see rectangles, look at ConceptVisionColorLocator_Rectangle
*
* Unlike a "color sensor" which determines the color of nearby object, this "color locator"
* will search the Region Of Interest (ROI) in a camera image, and find any "blobs" of color that
* match the requested color range. These blobs can be further filtered and sorted to find the one
* most likely to be the item the user is looking for.
*
* To perform this function, a VisionPortal runs a ColorBlobLocatorProcessor process.
* The ColorBlobLocatorProcessor (CBLP) process is created first, and then the VisionPortal is built.
* The (CBLP) analyses the ROI and locates pixels that match the ColorRange to form a "mask".
* The matching pixels are then collected into contiguous "blobs" of pixels.
* The outer boundaries of these blobs are called its "contour". For each blob, the process then
* creates the smallest possible circle that will fully encase the contour. The user can then call
* getBlobs() to retrieve the list of Blobs, where each contains the contour and the circle.
* Note: The default sort order for Blobs is ContourArea, in descending order, so the biggest
* contours are listed first.
*
* A colored enclosing circle is drawn on the camera preview to show the location of each Blob
* The original Blob contour can also be added to the preview.
* This is helpful when configuring the ColorBlobLocatorProcessor parameters.
*
* Tip: Connect an HDMI monitor to the Control Hub to view the Color Location process in real-time.
* Or use a screen copy utility like ScrCpy.exe to view the video remotely.
*
* Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
* Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list

* - Focus the color locator by defining a RegionOfInterest (ROI) which you want to search.
* This can be the entire frame, or a sub-region defined using:
* 1) standard image coordinates or 2) a normalized +/- 1.0 coordinate system.
* Use one form of the ImageRegion class to define the ROI.

* .setContourMode(ColorBlobLocatorProcessor.ContourMode.ALL_FLATTENED_HIERARCHY)

* EXTERNAL_ONLY helps to avoid bright reflection spots from breaking up solid colors.

* - Turn the displays of contours ON or OFF.
* Turning these on helps debugging but takes up valuable CPU time.
* .setDrawContours(true) Draws an outline of each contour.
* .setEnclosingCircleColor(int color) Draws a circle around each contour. 0 to disable.
* .setBoxFitColor(int color) Draws a rectangle around each contour. 0 to disable. ON by default.
*
*
* - include any pre-processing of the image or mask before looking for Blobs.
* There are some extra processing you can include to improve the formation of blobs.
* Using these features requires an understanding of how they may effect the final
* blobs. The "pixels" argument sets the NxN kernel size.
* .setBlurSize(int pixels)
* Blurring an image helps to provide a smooth color transition between objects,
* and smoother contours. The higher the number, the more blurred the image becomes.
* Note: Even "pixels" values will be incremented to satisfy the "odd number" requirement.
* Blurring too much may hide smaller features. A size of 5 is good for a 320x240 image.
*
* .setErodeSize(int pixels)
* Erosion removes floating pixels and thin lines so that only substantive objects remain.
* Erosion can grow holes inside regions, and also shrink objects.
* "pixels" in the range of 2-4 are suitable for low res images.
*
* .setDilateSize(int pixels)
* Dilation makes objects and lines more visible by filling in small holes, and making
* filled shapes appear larger. Dilation is useful for joining broken parts of an
* object, such as when removing noise from an image.
* "pixels" in the range of 2-4 are suitable for low res images.
*
* .setMorphOperationType(MorphOperationType morphOperationType)
* This defines the order in which the Erode/Dilate actions are performed.
* OPENING: Will Erode and then Dilate which will make small noise blobs go away
* CLOSING: Will Dilate and then Erode which will tend to fill in any small holes in blob edges.

/*
* This OpMode illustrates how to use a video source (camera) to locate specifically colored regions
*
* Unlike a "color sensor" which determines the color of nearby object, this "color locator"
* will search the Region Of Interest (ROI) in a camera image, and find any "blobs" of color that
* match the requested color range. These blobs can be further filtered and sorted to find the one
* most likely to be the item the user is looking for.
*
* To perform this function, a VisionPortal runs a ColorBlobLocatorProcessor process.
* The ColorBlobLocatorProcessor (CBLP) process is created first, and then the VisionPortal is built.
* The (CBLP) analyses the ROI and locates pixels that match the ColorRange to form a "mask".
* The matching pixels are then collected into contiguous "blobs" of pixels.
* The outer boundaries of these blobs are called its "contour". For each blob, the process then
* creates the smallest possible rectangle "boxFit" that will fully encase the contour. The user can
* then call getBlobs() to retrieve the list of Blobs, where each contains the contour and the boxFit.
* Note: The default sort order for Blobs is ContourArea, in descending order, so the biggest
* contours are listed first.
*
* A colored boxFit rectangle is drawn on the camera preview to show the location of each Blob
* The original Blob contour can also be added to the preview.
* This is helpful when configuring the ColorBlobLocatorProcessor parameters.
*
* Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
* Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list

*
* - Focus the color locator by defining a RegionOfInterest (ROI) which you want to search.
* This can be the entire frame, or a sub-region defined using:
* 1) standard image coordinates or 2) a normalized +/- 1.0 coordinate system.
* Use one form of the ImageRegion class to define the ROI.
* ImageRegion.entireFrame()

* ImageRegion.asUnityCenterCoordinates(-0.5, 0.5, 0.5, -0.5) 50% width/height in center
*
* - Define which contours are included.
* You can get ALL the contours, ignore contours that are completely inside another contour.
* .setContourMode(ColorBlobLocatorProcessor.ContourMode.ALL_FLATTENED_HIERARCHY)
* .setContourMode(ColorBlobLocatorProcessor.ContourMode.EXTERNAL_ONLY)
* EXTERNAL_ONLY helps to avoid bright reflection spots from breaking up solid colors.
*
* - turn the display of contours ON or OFF. Helps debugging but takes up valuable CPU time.
* .setDrawContours(true)
*
* - include any pre-processing of the image or mask before looking for Blobs.
* There are some extra processing you can include to improve the formation of blobs.
* Using these features requires an understanding of how they may effect the final blobs.
* The "pixels" argument sets the NxN kernel size.
* .setBlurSize(int pixels)
* Blurring an image helps to provide a smooth color transition between objects,
* and smoother contours. The higher the number, the more blurred the image becomes.
* Note: Even "pixels" values will be incremented to satisfy the "odd number" requirement.
* Blurring too much may hide smaller features. A size of 5 is good for a 320x240 image.
*
* .setErodeSize(int pixels)
* Erosion removes floating pixels and thin lines so that only substantive objects remain.
* Erosion can grow holes inside regions, and also shrink objects.
* "pixels" in the range of 2-4 are suitable for low res images.
*
* .setDilateSize(int pixels)
* Dilation makes objects and lines more visible by filling in small holes, and making
* filled shapes appear larger. Dilation is useful for joining broken parts of an
* object, such as when removing noise from an image.
* "pixels" in the range of 2-4 are suitable for low res images.

* ColorBlobLocatorProcessor.BlobCriteria.BY_ASPECT_RATIO
* A blob's Aspect ratio is the ratio of boxFit long side to short side.
* A perfect Square has an aspect ratio of 1. All others are > 1
*
* ColorBlobLocatorProcessor.BlobCriteria.BY_ARC_LENGTH
* A blob's arc length is the perimeter of the blob.
* This can be used in conjunction with an area filter to detect oddly shaped blobs.

* A "color sensor" will typically determine the color of the object that it is pointed at.

* The user may choose to inspect all, or just a Region of Interest (ROI), of the active camera view.
* The user must also provide a list of "acceptable colors" (Swatches) from which the closest matching
* color will be selected.
*
* To perform this function, a VisionPortal runs a PredominantColorProcessor process.
* The PredominantColorProcessor (PCP) process is created first, and then the VisionPortal is built.
* The (PCP) analyses the ROI and splits the colored pixels into several color-clusters.
* The largest of these clusters is then considered to be the "Predominant Color"
* The process then matches the Predominant Color with the closest Swatch and returns that match.
*
* To aid the user, a colored rectangle is drawn on the camera preview to show the RegionOfInterest,
* The Predominant Color is used to paint the rectangle border, so the user can visualize the color.
*
* Tip: Connect an HDMI monitor to the Control Hub to view the Color Sensor process in real-time.

* This code uses the Universal IMU interface so it will work with either the BNO055, or BHI260 IMU.
* To run as written, the Control/Expansion hub should be mounted horizontally on a flat part of the robot chassis.
* The REV Logo should be facing UP, and the USB port should be facing forward.
* If this is not the configuration of your REV Control Hub, then the code should be modified to reflect the correct orientation.
*
* This sample requires that the drive Motors have been configured with names : left_drive and right_drive.
* It also requires that a positive power command moves both motors forward, and causes the encoders to count UP.
* So please verify that both of your motors move the robot forward on the first move. If not, make the required correction.
* See the beginning of runOpMode() to set the FORWARD/REVERSE option for each motor.
*
* This code uses RUN_TO_POSITION mode for driving straight, and RUN_USING_ENCODER mode for turning and holding.
* Note: This code implements the requirement of calling setTargetPosition() at least once before switching to RUN_TO_POSITION mode.
*
* Notes:
*
* All angles are referenced to the coordinate-frame that is set whenever resetHeading() is called.
* In this sample, the heading is reset when the Start button is touched on the Driver Station.
* Note: It would be possible to reset the heading after each move, but this would accumulate steering errors.
*
* The angle of movement/rotation is assumed to be a standardized rotation around the robot Z axis,
* which means that a Positive rotation is Counter Clockwise, looking down on the field.
* This is consistent with the FTC field coordinate conventions set out in the document:
* https://ftc-docs.firstinspires.org/field-coordinate-system
*
* Control Approach.
*
* To reach, or maintain a required heading, this code implements a basic Proportional Controller where:
*
* Steering power = Heading Error * Proportional Gain.
*
* "Heading Error" is calculated by taking the difference between the desired heading and the actual heading,
* and then "normalizing" it by converting it to a value in the +/- 180 degree range.
*
* "Proportional Gain" is a constant that YOU choose to set the "strength" of the steering response.
*
* Use Android Studio to Copy this Class, and Paste it into your "TeamCode" folder with a new name.
* Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list

* This OpMode illustrates using a camera to locate and drive towards a specific AprilTag.
* The code assumes a Holonomic (Mecanum or X Drive) Robot.
*
* For an introduction to AprilTags, see the ftc-docs link below:
* https://ftc-docs.firstinspires.org/en/latest/apriltag/vision_portal/apriltag_intro/apriltag-intro.html
*
* When an AprilTag in the TagLibrary is detected, the SDK provides location and orientation of the tag, relative to the camera.
* This information is provided in the "ftcPose" member of the returned "detection", and is explained in the ftc-docs page linked below.
* https://ftc-docs.firstinspires.org/apriltag-detection-values
*
* The drive goal is to rotate to keep the Tag centered in the camera, while strafing to be directly in front of the tag, and
* driving towards the tag to achieve the desired distance.
* To reduce any motion blur (which will interrupt the detection process) the Camera exposure is reduced to a very low value (5mS)
* You can determine the best Exposure and Gain values by using the ConceptAprilTagOptimizeExposure OpMode in this Samples folder.
*
* The code assumes a Robot Configuration with motors named: front_left_drive and front_right_drive, back_left_drive and back_right_drive.
* The motor directions must be set so a positive power goes forward on all wheels.
* This sample assumes that the current game AprilTag Library (usually for the current season) is being loaded by default,
* so you should choose to approach a valid tag ID.
*
* Under manual control, the left stick will move forward/back & left/right. The right stick will rotate the robot.
* Manually drive the robot until it displays Target data on the Driver Station.
*
* Press and hold the *Left Bumper* to enable the automatic "Drive to target" mode.
* Release the Left Bumper to return to manual driving mode.
*
* Under "Drive To Target" mode, the robot has three goals:
* 1) Turn the robot to always keep the Tag centered on the camera frame. (Use the Target Bearing to turn the robot.)
* 2) Strafe the robot towards the centerline of the Tag, so it approaches directly in front of the tag. (Use the Target Yaw to strafe the robot)
* 3) Drive towards the Tag to get to the desired distance. (Use Tag Range to drive the robot forward/backward)
*
* Use DESIRED_DISTANCE to set how close you want the robot to get to the target.
* Speed and Turn sensitivity can be adjusted using the SPEED_GAIN, STRAFE_GAIN and TURN_GAIN constants.
*
* Use Android Studio to Copy this Class, and Paste it into the TeamCode/src/main/java/org/firstinspires/ftc/teamcode folder.
* Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list.

* This OpMode illustrates using a camera to locate and drive towards a specific AprilTag.
* The code assumes a basic two-wheel (Tank) Robot Drivetrain
*
* For an introduction to AprilTags, see the ftc-docs link below:
* https://ftc-docs.firstinspires.org/en/latest/apriltag/vision_portal/apriltag_intro/apriltag-intro.html
*
* When an AprilTag in the TagLibrary is detected, the SDK provides location and orientation of the tag, relative to the camera.
* This information is provided in the "ftcPose" member of the returned "detection", and is explained in the ftc-docs page linked below.
* https://ftc-docs.firstinspires.org/apriltag-detection-values
*
* The driving goal is to rotate to keep the tag centered in the camera, while driving towards the tag to achieve the desired distance.
* To reduce any motion blur (which will interrupt the detection process) the Camera exposure is reduced to a very low value (5mS)
* You can determine the best exposure and gain values by using the ConceptAprilTagOptimizeExposure OpMode in this Samples folder.
*
* The code assumes a Robot Configuration with motors named left_drive and right_drive.
* The motor directions must be set so a positive power goes forward on both wheels;
* This sample assumes that the default AprilTag Library (usually for the current season) is being loaded by default
* so you should choose to approach a valid tag ID.
*
* Under manual control, the left stick will move forward/back, and the right stick will rotate the robot.
* This is called POV Joystick mode, different than Tank Drive (where each joystick controls a wheel).
*
* Manually drive the robot until it displays Target data on the Driver Station.
* Press and hold the *Left Bumper* to enable the automatic "Drive to target" mode.
* Release the Left Bumper to return to manual driving mode.
*
* Under "Drive To Target" mode, the robot has two goals:
* 1) Turn the robot to always keep the Tag centered on the camera frame. (Use the Target Bearing to turn the robot.)
* 2) Drive towards the Tag to get to the desired distance. (Use Tag Range to drive the robot forward/backward)
*
* Use DESIRED_DISTANCE to set how close you want the robot to get to the target.
* Speed and Turn sensitivity can be adjusted using the SPEED_GAIN and TURN_GAIN constants.
*
* Use Android Studio to Copy this Class, and Paste it into the TeamCode/src/main/java/org/firstinspires/ftc/teamcode folder.
* Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list.

* The sample will display the current Yaw, Pitch and Roll of the robot.

* Roll value should INCREASE as the robot is tipped UP at the left side. (Rotation about Y)
* Yaw value should INCREASE as the robot is rotated Counter Clockwise. (Rotation about Z)
*
* The yaw can be reset (to zero) by pressing the Y button on the gamepad (Triangle on a PS4 controller).

* Note: if your AndyMark IMU is mounted Orthogonally (on a orthogonal surface, angled at some

/* Define how the AndyMark IMU is mounted to the robot to get the correct Yaw, Pitch, and
* Roll values.
*
* You can apply up to three axis rotations to orient your AndyMark IMU according to how
* it's mounted on the robot.
*
* The starting point for these rotations is the "Default" IMU orientation, which is:
* 1) IMU laying flat on a horizontal surface, with the AndyMark logo facing up.
* 2) Rotated such that the I2C port is facing forward on the robot.
*
* The order that the rotations are performed matters, so this sample shows doing them in
* the order X, Y, then Z.
* For specifying non-orthogonal IMU mounting orientations, we must temporarily use axes
* defined relative to the AndyMark IMU itself, instead of the usual Robot Coordinate System
* axes used for the results the AndyMark IMU gives us. In the starting orientation, the
* AndyMark IMU axes are aligned with the Robot Coordinate System:
*
* X Axis: Starting at center of IMU, pointing out towards the side.
* Y Axis: Starting at center of IMU, pointing out towards I2C port.
* Z Axis: Starting at center of IMU, pointing up through the AndyMark logo.
*
* Positive rotation is defined by right-hand rule with thumb pointing in +ve direction on
* axis.
*
* Some examples.
*
* ----------------------------------------------------------------------------------------------------------------------------------
* Example A) Assume that the AndyMark IMU is mounted on a sloped plate at the back of the
* robot, with the I2C port coming out the top of the AndyMark IMU. The plate is tilted UP
* 60 degrees from horizontal.
*
* To get the "Default" IMU into this configuration you would just need a single rotation.
* 1) Rotate the AndyMark IMU +60 degrees around the X axis to tilt up the front edge.
* 2) No rotation around the Y or Z axes.
*
* So the X,Y,Z rotations would be 60,0,0
*
* ----------------------------------------------------------------------------------------------------------------------------------
* Example B) Assume that the AndyMark IMU is laying flat on the chassis, but it has been
* twisted 30 degrees towards the right front wheel.
*
* To get the "Default" IMU into this configuration you would just need a single rotation,
* but around a different axis.
* 1) No rotation around the X or Y axes.
* 2) Rotate the AndyMark IMU -30 degrees (Clockwise) around the Z axis, since a positive
* angle would be Counter Clockwise.
*
* So the X,Y,Z rotations would be 0,0,-30
*
* ----------------------------------------------------------------------------------------------------------------------------------
* Example C) Assume that the AndyMark IMU is mounted on a vertical plate on the right side
* of the robot, with the AndyMark logo facing out, and the AndyMark IMU rotated so that the
* I2C port is facing down 30 degrees towards the back wheels of the robot.
*
* To get the "Default" IMU into this configuration will require several rotations.
* 1) Rotate the AndyMark IMU +90 degrees around the X axis to get it standing upright with
* the logo pointing backwards on the robot
* 2) Next, rotate the AndyMark IMU +90 around the Y axis to get the logo facing to the
* right.
* 3) Finally rotate the AndyMark IMU +120 degrees around the Z axis to take the I2C port
* from vertical to sloping down 30 degrees and facing towards the back of the robot.
*
* So the X,Y,Z rotations would be 90,90,120

* This OpMode calibrates a BNO055 IMU per

* Manual calibration of the IMU is definitely NOT necessary: except for the magnetometer (which is not used by the

*
* "This device requires calibration in order to operate accurately. [...] Calibration data is
* lost on a power cycle. See one of the examples for a description of how to calibrate the device,
* but in essence:
*
* There is a calibration status register available [...] that returns the calibration status
* of the accelerometer (ACC), magnetometer (MAG), gyroscope (GYR), and overall system (SYS).
* Each of these values range from 0 (uncalibrated) to 3 (fully calibrated). Calibration [ideally]
* involves certain motions to get all 4 values at 3. The motions are as follows (though see the
* datasheet for more information):
*
* 1. GYR: Simply let the sensor sit flat for a few seconds.</ol>
* 2. ACC: Move the sensor in various positions. Start flat, then rotate slowly by 45
* degrees, hold for a few seconds, then continue rotating another 45 degrees and
* hold, etc. 6 or more movements of this type may be required. You can move through
* any axis you desire, but make sure that the device is lying at least once
* perpendicular to the x, y, and z axis.</ol>
* 3. MAG: Move slowly in a figure 8 pattern in the air, until the calibration values reaches 3.</ol>
* 4. SYS: This will usually reach 3 when the other items have also reached 3. If not, continue
* slowly moving the device though various axes until it does."</ol>
*
* To calibrate the IMU, run this sample OpMode with a gamepad attached to the driver station.
* Once the IMU has reached sufficient calibration as reported on telemetry, press the 'A'
* button on the gamepad to write the calibration to a file. That file can then be indicated
* later when running an OpMode which uses the IMU.
*
* Note: if your intended uses of the IMU do not include use of all its sensors (for example,
* you might not use the magnetometer), then it makes little sense for you to wait for full
* calibration of the sensors you are not using before saving the calibration data. Indeed,
* it appears that in a SensorMode that doesn't use the magnetometer (for example), the
* magnetometer cannot actually be calibrated.

* This OpMode shows how to use a color sensor in a generic
* way, regardless of which particular make or model of color sensor is used. The OpMode
* assumes that the color sensor is configured with a name of "sensor_color".
*
* There will be some variation in the values measured depending on the specific sensor you are using.
*
* If the color sensor supports adjusting the gain, you can increase the gain (a multiplier to make
* the sensor report higher values) by holding down the A button on the gamepad, and decrease the
* gain by holding down the B button on the gamepad. The AndyMark Proximity & Color Sensor does not
* support this.
*
* If the color sensor has a light which is controllable from software, you can use the X button on
* the gamepad to toggle the light on and off. The REV sensors don't support this, but instead have
* a physical switch on them to turn the light on and off, beginning with REV Color Sensor V2. The
* AndyMark Proximity & Color Sensor does not support this.
*
* If the color sensor also supports short-range distance measurements (usually via an infrared
* proximity sensor), the reported distance will be written to telemetry. As of September 2025,
* the only color sensors that support this are the ones from REV Robotics and the AndyMark
* Proximity & Color Sensor. These infrared proximity sensor measurements are only useful at very
* small distances, and are sensitive to ambient light and surface reflectivity. You should use a
* different sensor if you need precise distance measurements.

/* Define how the hub is mounted to the robot to get the correct Yaw, Pitch and Roll values.
*
* You can apply up to three axis rotations to orient your Hub according to how it's mounted on the robot.
*
* The starting point for these rotations is the "Default" Hub orientation, which is:
* 1) Hub laying flat on a horizontal surface, with the Printed Logo facing UP
* 2) Rotated such that the USB ports are facing forward on the robot.
*
* If you are using a REV External IMU, the "Default" orientation is the same as for a REV Hub, but instead of
* the USB ports facing forward, the I2C port faces forward.
*
* The order that the rotations are performed matters, so this sample shows doing them in the order X, Y, then Z.
* For specifying non-orthogonal hub mounting orientations, we must temporarily use axes
* defined relative to the Hub itself, instead of the usual Robot Coordinate System axes
* used for the results the IMU gives us. In the starting orientation, the Hub axes are
* aligned with the Robot Coordinate System:
*
* X Axis: Starting at Center of Hub, pointing out towards I2C connectors
* Y Axis: Starting at Center of Hub, pointing out towards USB connectors
* Z Axis: Starting at Center of Hub, pointing Up through LOGO
*
* Positive rotation is defined by right-hand rule with thumb pointing in +ve direction on axis.
*
* Some examples.
*
* ----------------------------------------------------------------------------------------------------------------------------------
* Example A) Assume that the hub is mounted on a sloped plate at the back of the robot, with the USB ports coming out the top of the hub.
* The plate is tilted UP 60 degrees from horizontal.
*
* To get the "Default" hub into this configuration you would just need a single rotation.
* 1) Rotate the Hub +60 degrees around the X axis to tilt up the front edge.
* 2) No rotation around the Y or Z axes.
*
* So the X,Y,Z rotations would be 60,0,0
*
* ----------------------------------------------------------------------------------------------------------------------------------
* Example B) Assume that the hub is laying flat on the chassis, but it has been twisted 30 degrees towards the right front wheel to make
* the USB cable accessible.
*
* To get the "Default" hub into this configuration you would just need a single rotation, but around a different axis.
* 1) No rotation around the X or Y axes.
* 2) Rotate the Hub -30 degrees (Clockwise) around the Z axis, since a positive angle would be Counter Clockwise.
*
* So the X,Y,Z rotations would be 0,0,-30
*
* ----------------------------------------------------------------------------------------------------------------------------------
* Example C) Assume that the hub is mounted on a vertical plate on the right side of the robot, with the Logo facing out, and the
* Hub rotated so that the USB ports are facing down 30 degrees towards the back wheels of the robot.
*
* To get the "Default" hub into this configuration will require several rotations.
* 1) Rotate the hub +90 degrees around the X axis to get it standing upright with the logo pointing backwards on the robot
* 2) Next, rotate the hub +90 around the Y axis to get it facing to the right.
* 3) Finally rotate the hub +120 degrees around the Z axis to take the USB ports from vertical to sloping down 30 degrees and
* facing towards the back of the robot.
*
* So the X,Y,Z rotations would be 90,90,120

* This OpMode illustrates how to use DigitalChickenLabs OctoQuad Quad Encoder & Pulse Width I/F Module
*
* The OctoQuad has 8 input channels that can used to read either Relative Quadrature Encoders or
* Pulse-Width Absolute Encoder inputs. Relative Quadrature encoders are found on most FTC motors,
* and some stand-alone position sensors like the REV Thru-Bore encoder. Pulse-Width encoders are
* less common. The REV Thru-Bore encoder can provide its absolute position via a variable pulse width,
* as can several sonar rangefinders such as the MaxBotix MB1000 series.
*
* Note: SDK 11.0+ requires that the OctoQuad is running firmware V3.0 or greater.
* Visit https://github.com/DigitalChickenLabs/OctoQuad/tree/master/firmware for instruction
* on how to upgrade your OctoQuad's firmware.
*
* This basic sample shows how an OctoQuad can be used to read the position of three Odometry pods
* fitted with REV Thru-Bore encoders. For a more advanced example with additional OctoQuad
* capabilities, see the SensorOctoQuadAdv sample.
*
* This OpMode assumes the OctoQuad is attached to an I2C interface named "octoquad" in the robot config.
*
* The code assumes the first three OctoQuad inputs are connected as follows
* - Chan 0: for measuring forward motion on the left side of the robot.
* - Chan 1: for measuring forward motion on the right side of the robot.
* - Chan 2: for measuring Lateral (strafing) motion.
*
* The encoder values may be reset to zero by pressing the X (left most) button on Gamepad 1.
*
* This sample does not show how to interpret these readings, just how to obtain and display them.
*
* Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
* Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list
*
* See the sensor's product page: https://www.tindie.com/products/35114/

/*
* This OpMode illustrates how to use advanced features of the DigitalChickenLabs OctoQuad Quadrature
* Encoder & Pulse Width Interface Module. The OctoQuad has 8 input channels that can used to read
* either Quadrature Encoder signals (like with most FTC motors) or Pulse-Width style Absolute Encoder
* inputs (eg: REV Through Bore encoder pulse width output).
*
* This OpMode illustrates several of the more advanced features of an OctoQuad, including Pulse Width
* measurement and velocity measurement. For a more basic OpMode just showing how to read encoder
* inputs, see the SensorOctoQuad sample.
*
* This OpMode assumes the OctoQuad is attached to an I2C interface named "octoquad" in the robot config.
*
* One system that requires a lot of encoder inputs is a Swerve Drive system.
* Such a drive requires two encoders per drive module:
* One encoder for the Drive motor/wheel position.velocity, and one for Steer motor angle.
* The Drive motor requires a quadrature encoder, and the Steering motor requires an Absolute encoder.
*
* This sample will configure an OctoQuad for a swerve drive, as follows
* - Configure 4 Relative Quadrature Encoder inputs and 4 Absolute Pulse-Width Encoder inputs
* - Configure a velocity sample interval of 25 mSec
* - Configure a pulse width input range of 1-1024 uSec for a REV Encoder's Absolute Pulse output.
*
* An OctoSwerveDrive class will be created to initialize the OctoQuad, and manage 4 swerve modules.
* An OctoSwerveModule class will be created to configure and read a single swerve module.
*
* Wiring:
* The OctoQuad will be configured to accept Quadrature encoders on the first four channels and
* Absolute (pulse width) encoders on the last four channels.
*
* The standard encoder cable will connect each Driver Motor encoder to the OctoQuad. (channels 0-3)
*
* A modified version of the REV 6-4 pin cable (shipped with the encoder) connects the steering encoder
* to the OctoQuad. (channels 4-7)
*
* To connect the Absolute position signal from a REV Thru-Bore encoder to the OctoQuad, the
* Provided 6-pin to 4-pin cable will need to be modified.
* At the 6-pin connector end, move the yellow wire from its initial pin-3 position to the
* ABS pin-5 position. This can be done easily by using a small flathead screwdriver to lift the
* small white tab holding the metal wire crimp in place and gently pulling the wire out.
* See the OctoSwerveDrive() constructor below for the correct wheel/channel assignment.
*
* Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
* Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list
*
* See the sensor's product page: https://www.tindie.com/products/35114/

// firmware version 1.0, these values will be lost after a power cycle, so
// you will need to set them each time you power up the sensor. For example, if
// the sensor is mounted 5 inches to the left (negative X) and 10 inches
// forward (positive Y) of the center of the robot, and mounted 90 degrees
// clockwise (negative rotation) from the robot's orientation, the offset
// would be {-5, 10, -90}. These can be any value, even the angle can be

// need to set them each time you power up the sensor. They can be any value
// from 0.872 to 1.127 in increments of 0.001 (0.1%). It is recommended to
// first set both scalars to 1.0, then calibrate the angular scalar, then
// the linear scalar. To calibrate the angular scalar, spin the robot by
// multiple rotations (eg. 10) to get a precise error, then set the scalar
// to the inverse of the error. Remember that the angle wraps from -180 to
// 180 degrees, so for example, if after 10 rotations counterclockwise
// (positive rotation), the sensor reports -15 degrees, the required scalar
// would be 3600/3585 = 1.004. To calibrate the linear scalar, move the
// robot a known distance and measure the error; do this multiple times at
// multiple speeds to get an average, then set the linear scalar to the
// inverse of the error. For example, if you move the robot 100 inches and
// the sensor reports 103 inches, set the linear scalar to 100/103 = 0.971
myOtos.setLinearScalar(1.0);
myOtos.setAngularScalar(1.0);
// The IMU on the OTOS includes a gyroscope and accelerometer, which could
// have an offset. Note that as of firmware version 1.0, the calibration
// will be lost after a power cycle; the OTOS performs a quick calibration
// when it powers up, but it is recommended to perform a more thorough
// calibration at the start of all your OpModes. Note that the sensor must
// be completely stationary and flat during calibration! When calling
// calibrateImu(), you can specify the number of samples to take and whether
// to wait until the calibration is complete. If no parameters are provided,
// it will take 255 samples and wait until done; each sample takes about
// 2.4ms, so about 612ms total

// Reset the tracking algorithm - this resets the position to the origin,
// but can also be used to recover from some rare tracking errors

// After resetting the tracking, the OTOS will report that the robot is at

/*
* This OpMode illustrates how to use an external "hardware" class to modularize all the robot's sensors and actuators.
* This approach is very efficient because the same hardware class can be used by all of your teleop and autonomous OpModes
* without requiring many copy & paste operations. Once you have defined and tested the hardware class with one OpMode,
* it is instantly available to other OpModes.
*
* The real benefit of this approach is that as you tweak your robot hardware, you only need to make changes in ONE place (the Hardware Class).
* So, to be effective you should put as much or your hardware setup and access code as possible in the hardware class.
* Essentially anything you do with hardware in BOTH Teleop and Auto should likely go in the hardware class.
*
* The Hardware Class is created in a separate file, and then an "instance" of this class is created in each OpMode.
* In order for the class to do typical OpMode things (like send telemetry data) it must be passed a reference to the
* OpMode object when it's created, so it can access all core OpMode functions. This is illustrated below.
*
* In this concept sample, the hardware class file is called RobotHardware.java and it must accompany this sample OpMode.
* So, if you copy ConceptExternalHardwareClass.java into TeamCode (using Android Studio or OnBotJava) then RobotHardware.java
* must also be copied to the same location (maintaining its name).
*
* For comparison purposes, this sample and its accompanying hardware class duplicates the functionality of the
* RobotTelopPOV_Linear OpMode. It assumes three motors (left_drive, right_drive and arm) and two servos (left_hand and right_hand)
*
* View the RobotHardware.java class file for more details
*
* Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
* Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list
*
* In OnBot Java, add a new OpMode, select this sample, and select TeleOp.
* Also add another new file named RobotHardware.java, select the sample with that name, and select Not an OpMode.

## Caution
No Team-specific code should be placed or modified in this ``.../samples`` folder.
Samples should be Copied from here, and then Pasted into the team's
[/TeamCode/src/main/java/org/firstinspires/ftc/teamcode](../../../../../../../../../../TeamCode/src/main/java/org/firstinspires/ftc/teamcode)
folder, using the Android Studio cut and paste commands. This automatically changes all file and
class names to be consistent. From there, the sample can be modified to suit the team's needs.
For more detailed instructions see the /teamcode readme.
### Naming of Samples
To gain a better understanding of how the samples are organized, and how to interpret the
naming system, it will help to understand the conventions that were used during their creation.
These conventions are described (in detail) in the sample_conventions.md file in this folder.
To summarize: A range of different samples classes will reside in the java/external/samples.
The class names will follow a naming convention which indicates the purpose of each class.
The prefix of the name will be one of the following:
Basic: This is a minimally functional OpMode used to illustrate the skeleton/structure
of a particular style of OpMode. These are bare bones examples.
Sensor: This is a Sample OpMode that shows how to use a specific sensor.
It is not intended to drive a functioning robot, it is simply showing the minimal code
required to read and display the sensor values.
Robot: This is a Sample OpMode that assumes a simple two-motor (differential) drive base.
It may be used to provide a common baseline driving OpMode, or
to demonstrate how a particular sensor or concept can be used to navigate.
Concept: This is a sample OpMode that illustrates performing a specific function or concept.
These may be complex, but their operation should be explained clearly in the comments,
or the comments should reference an external doc, guide or tutorial.
Each OpMode should try to only demonstrate a single concept so they are easy to
locate based on their name. These OpModes may not produce a drivable robot.
After the prefix, other conventions will apply:
* Sensor class names are constructed as: Sensor - Company - Type
* Robot class names are constructed as: Robot - Mode - Action - OpModetype
* Concept class names are constructed as: Concept - Topic - OpModetype

## Sample Class/Opmode conventions
#### V 1.1.0 8/9/2017
This document defines the FTC Sample OpMode and Class conventions.
### OpMode Name
To gain a better understanding of how the samples are organized, and how to interpret the
naming system, it will help to understand the conventions that were used during their creation.
To summarize: A range of different samples classes will reside in the java/external/samples.
The class names will follow a naming convention which indicates the purpose of each class.
The prefix of the name will be one of the following:
Basic: This is a minimally functional OpMode used to illustrate the skeleton/structure
of a particular style of OpMode. These are bare bones examples.
Sensor: This is a Sample OpMode that shows how to use a specific sensor.
It is not intended to drive a functioning robot, it is simply showing the minimal code
required to read and display the sensor values.
Robot: This is a Sample OpMode that assumes a simple two-motor (differential) drive base.
It may be used to provide a common baseline driving OpMode, or
to demonstrate how a particular sensor or concept can be used to navigate.
Concept: This is a sample OpMode that illustrates performing a specific function or concept.
These may be complex, but their operation should be explained clearly in the comments,
or the comments should reference an external doc, guide or tutorial.
Each OpMode should try to only demonstrate a single concept so they are easy to
locate based on their name. These OpModes may not produce a drivable robot.
Utility: This sample type is provided as a useful tool, or aide, to perform some specific development task.
It is not expected to be something you would include in your own robot code.
To use the tool, comment out the @Disabled annotation and build the App.
Read the comments found in the sample for an explanation of its intended use.
After the prefix, other conventions will apply:
* Sensor class names should constructed as: Sensor - Company - Type
* Robot class names should be constructed as: Robot - Mode - Action - OpModetype
* Concept class names should be constructed as: Concept - Topic - OpModetype
### Sample OpMode Content/Style
Code is formatted as per the Google Style Guide:
https://google.github.io/styleguide/javaguide.html
With “Sensor” and “Hardware” samples, the code should demonstrate the essential function,
and not be embellished with too much additional “clever” code. If a sensor has special
addressing needs, or has a variety of modes or outputs, these should be demonstrated as
simply as possible.
Special programming methods, or robot control techniques should be reserved for “Concept” Samples,
and where possible, Samples should strive to only demonstrate a single concept,
eg: State machine coding, or a User Menu system, and not combine them into a single “all inclusive”
sample. This will prevent an “all inclusive” Sample being deleted just because one part of it
becomes obsolete.
### Device Configuration Names
The following device names are used in the external samples
** Motors:
left_drive
right_drive
left_arm
** Servos:
left_hand
right_hand
arm
claw
** Sensors:
sensor_color
sensor_ir
sensor_light
sensor_ods
sensor_range
sensor_touch
sensor_color_distance
sensor_digital
digin
digout
** Localization:
compass
gyro
imu
navx
### Device Object Names
Device Object names should use the same words as the device’s configuration name, but they
should be re-structured to be a suitable Java variable name. This should keep the same word order,
but adopt the style of beginning with a lower case letter, and then each subsequent word
starting with an upper case letter.
Eg: from the examples above: tool, leftMotor, rightClawServo, rearLightSensor.
Note: Sometimes it’s helpful to put the device type first, followed by the variant.
eg: motorLeft and motorRight, but this should only be done if the same word order
is used on the device configuration name.
### OpMode code Comments
Sample comments should read like normal code comments, that is, as an explanation of what the
sample code is doing. They should NOT be directives to the user,
like: “insert your joystick code here” as these comments typically aren’t
detailed enough to be useful. They also often get left in the code and become garbage.
Instead, an example of the joystick code should be shown with a comment describing what it is doing.
