ABSTRACT:
This invention relates to a synchronous mechanical motor controller for use in robot applications requiring precise and repeatable movements. The synchronous motor controller is an arrangement of separate electric motors driving individual wheels and operating in harmony with each wheel through multiple bevel gear sets having independent servos. A shaft revolution counter allows the robot to learn and repeat its movements. An onboard radio receiver and transmitter allows an operator to remotely teach the robot its movements. The arrangement of electric motors, bevel gear sets, and servos allowing the robot to run straight, turn, or pivot as required and to accurately reverse its steps so as to return to the same point from which it started.
