A Novel Bio-mimetic Wireless Micro Robot for Endoscope

Abstract

A novel bio-mimetic wireless micro robot for endoscope is developed.Its autonomous manner is earthworm-like and driven by linear actuators based on DC motor.It is different from the conventional micro robot endoscope that wireless module is used for communicating and power transfer.The fabricated micro robot system is detailedly described,including structure,micro robot locomotion principle,communication control module and wireless power transfer module.The experimental results show that the driving force of the linear actuator can reach to 2.55 N and supplying power is up to 480 mW DC power for receiving coil in the proposed system,which all fulfill the need of the micro robot system.The micro robot can creep reliably in the large intestine of pig and other contact environments.
