The measurement system of energy consumption is designed for clothes model legs using robot control technology.The DC motor’s speed is regulated by PWM speed regulation

and the swing guide bar is drived by the worm gear reducer.Then the model legs swing is drived forward and backward in normal step.The measurement circuit transfer the voltage and current of the DC motor and the model steps number to the host computer to process datas to achieve measurement of power and steps number of the robot.The experiments show the system has high measurement precision

good repetitivity.It is the basis of the further research on the principle and evaluation system of the clothes energy consumption.
