Abstract
A method for controlling a motorized balancing transporter that has two wheels in contact with the ground in normal operation. A signal substantially proportional to the shaft velocity is produced, and, at a rate less than 200 times per second, a voltage is calculated based at least on the shaft velocity signal and a specified transporter velocity and a voltage is applied to the motor based on the calculated voltage. A method is also provided for yaw control of the motorized balancing transporter that includes calculating a command to a motor amplifier based on balancing requirements of the transporter and augmenting the command to the motor amplifier based on a specified direction of motion.
