Arcade drive Arcade drive is a method of controlling the motors of a tank drive drivetrain using two axes of a controller, where one of the axes controls the speed of the robot, and the other the steering of the robot. Sometimes the same joystick is used for both, but this reduces the Arcade Drive - one joystick axis controlling robot movement and turns. Tank Drive The tank drivetrain is the simplest to build and consists of two tracks with wheels on each side. The rotation argument controls the curvature of the robot’s path rather than its rate of heading change. Below is an example of single stick and double stick curvature drive: Single Stick Using the DifferentialDrive class to control Differential Drive (WCD) robots ¶ Note WPILib provides separate Robot Drive classes for the most common drive train configurations (differential, mecanum, and Killough). We give the robot a forwards/backwards speed, and the curvature of an arc. Tank drive is a method of controlling the motors of a tank drive drivetrain using two axes of a controller, where each of the axes operate motors on one side of the robot (see image below, or this video).

Tutorial 4: Cheezy Drive What Curvature Drive, or "Cheesy Drive", is a controller mapping for operator control that was first popularized by Team 254, The Cheesy Poofs, of FRC. The same equations apply to 6WD drive, BUT The closer the CoG is to the middle the closer the robot rotates on its centre AND, the closer the CoG is to the middle, the less force is required to overcome friction from the wheels Oct 16, 2022 · Just to clarify, the main benefit of pure pursuit is being able to do curved turns, right? what else does pure pursuit help with? Drive the Robot We calculate the curvature our robot must take to get to the lookahead point Next we determine the target velocity using the closest point to the robot (calculated above) as our max speed, for slowing around turns, and using a rate limiter to limit acceleration Wheel Velocities es at, we can control the left and right wheel speeds. Curvature drive is only slightly different from arcade drive. To get started, make sure you have calibrated the zero offsets Intuitively, the curvature describes for any part of a curve how much the curve direction changes over a small distance travelled, so it is a measure of the instantaneous rate of change of direction of a point that moves on the curve: the larger the curvature, the larger this rate of change.
