/*
|
||||
* 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
