Wireless Measurement and Control System for a Novel Bionic Micro-Robot

A measurement and control system based on magnetic field and radio signal is designed,which controls the magnetotactic bacterium-like micro-robot and measures its experimental parameters with wireless method.The measurement and control system consists of micro-robot posture measurement subsystem and micro-robot control subsystem.In the mea-surement subsystem,state of the micro-robot is obtained by processing the signal detected with magnetic sensors array in real time,and is compared with video tracking result.In the control subsystem,the speed of micro-robot is controlled by PWM(pulse-width modulation) signals of radio transmitter,and the orientation of the micro-robot is controlled by guide magnetic field.90º turning movement control is studied experimentally in the system.And results verify that the system can effectively control the bionic micro-robot.
