Non invasive micro robotic colonoscope can be applied in health care to find the malignant tumor in its early stage. This project presented a novel squirm robot prototype with 13 mm diameter, 105 mm length, and 22.3 g weight. The robot is actuated by three linear motors which are composed of micro motor, turbine-worm, and wire wrapping-sliding mechanism. This linear actuators are featured with the...
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...
This paper reports a novel wireless powered bionic microrobot, which is supposed to be used as an endoscope. The detection system is detailedly described, including microrobot structure, wireless power transmission system, RF communication and imaging module. Earthworm-like multi-segment squirm mechanism is designed and manufactured driven by dc motors. Double closed-loop control strategy ensures...
