Tank Drive

Tank drive is a control scheme for controlling the drivetrain. With this, the controller's left joystick controls the left side of the robot, while the right joystick controls the right side of the robot.

This control scheme is very easy to code, but can be unintuitive for an inexperienced driver. Some drivers prefer this control scheme due to it's increased level of control.
