Abstract:This paper reports a novel wireless robotic endoscope.Researches are carried out on the subsystems of wireless powering,communication and imaging.The tethering problem which prevents the robot from going further into the body is overcome by wireless power transmission.Power up to 800 mW can be transmitted at an efficiency of 3~8% based on the designed double closed-loop control strategy,laying a foundation for further research on non-invasive or minimal invasive devices.Vedio data inside the body can be transmitted outside via the miniature imaging device on the robot head at a frame rate of 30fps.The robot prototype is 12 mm in diameter and 150 mm in length.The results of in vitro porcine colon experiments show that this robotic endoscope is suitable for soft and slippery tissues.
