Micro-Robot for Endoscope Based on Wireless Power Transfer

This paper proposes a new prototype of wireless micro-robot system for endoscope. The micro-robot we have fabricated and tested is able to propel itself in the intestine canal of pig in an autonomous manner by earthworm locomotion. It is different from the conventional micro-robot endoscope that wireless module is used for communicating and power transfer being up to 480 mW of DC power for receiving coil in the proposed system. The system composes of wireless communications module, personal computer, micro-robot, wireless power transfer controller and wireless power transfer coil. The experimental results show that the driving voltage of micro-robot is stable which fulfils the need of the micro-robot system. The micro-robot can creep reliably in the rubber canal and the intestinal canal of pig.
