Presets
A differential-drive robot steers by spinning its two wheels at different speeds — like a tank. Equal speeds go straight, a difference curves the path, and opposite speeds spin in place. Its forward speed is the average of the wheels and its turn rate is their difference over the wheelbase.

Reading this result: The faster right wheel pushes the robot into an arc that curves toward the slower left side, with radius set by how close the two speeds are.
