Simon Monk presents several Raspberry Pi robotics components including the RaspiRobotBoard motor controller board and Chronos EZ-430 programmable sensor board. He demonstrates a basic robot chassis controlled with the RaspiRobotBoard using crude PWM for motor speed control. Finally, he provides his contact information and advertises several of his books for sale.
