| The human gastrointestinal tract disease is a chronic disease, it has a high mortality and high morbidity characteristics. At present, the use of endoscopy is the main way to diagnose gastrointestinal diseases, in this way patients will withstand extreme discomfort and pain. In this paper, a micro-robot, designed to check the gastrointestinal tract, to solve the shortcomings that traditional gastrointestinal endoscopy brought.In this paper, the use of wireless technology to provide electrical power for the micro robott, and the wireless energy supply technology is mainly based on the principle of electromagnetic induction. The transmitting coil using a Helmholtz coil, the receiving coil using a three-dimensional orthogonal coil.In the receiving circuit also adds a rectifying circuit, the last three output terminals in parallel mode to provide power to the load. In order to improve the efficiency of wireless energy transfer, so the transmitting circuit and the receiving circuit shoud be resonanting up at the same frequency.After a careful analysis of the movement mode of the robot, and a careful analysis of the robot common drive mode, to finalize the imitation inchworm's movement is the movement of micro-robot. Imitation inchworm's movement is driven by a drive DC motor.The micro-robot control circuits are studied in detail. The control signal from the PC through the serial port is passed to the external transmitting signal control module, and the external transmitting signal control module transmits it wirelessly. In this way, the control signal is received by the receiving signal control module. After further processing, the control signal could control the movement of the robot.Finally, in order to verify the effectiveness of the system, do a confirmatory test. When the voltage of the LC circuit that composed by transmitting coils and receiving coils is 12V, the resonant frequency is 433Hz, transmit power is 12.5W, The power receiving coils can receive at least 380mW power. |
