1. Steering Motor Calibration
Autocalibration
Turn on robot and controller. With SWA flipped to down position, and VRA pushed to bottommost position, press KEY1.
Manual Calibration
Turn off robot and controller. While robot is turned off, adjust the position of the steering wheels. Using a long straight object to help straighten the wheels is generally sufficient.
