Abstract

For the control of multiple servomotors in a humanoid robots, a communication system is proposed. In the system, DC electric power, command/response signals and a common clock signal for precise synchronous movement of the servomotors are transmitted via the same wiring with a multi-drop bus. Because of the bandwidth limitation, the common clock signal and the command/response signals overlap each other. It is confirmed that the coexistence of both signals is possible by using interference cancellation at the reception of command/response signals.
