To realize long work hours of a humanoid robot without cable

a control system using distributed power is designed.Humanoid robot joint motor drives with separate power supply of dynamic power and digital way.Dynamic power mainly supply for motor

while the digital power mainly supply for the control chip.So that the control system use distributed power scheme

that is to say

a battery pack supply for a number of digital electric part of joint drive

while dynamic electric of each joint drive is supplied by a single battery pack.The feasibility of this method is verified in multi-motor control system.It becomes possible to work long time for humanoid robot.
