Simulation Analysis on the Bionic Micro Robot Operating in the Vascular Environment

Based on the motion principle of gastropod, a novel interventional minimal invasive robot which has the ability to run smoothly in the biological lumen with impulsive flowing liquid has been presented. Simulation models of the interventional micro robot operating in the straight or the bend blood vessels have been established with the software of Fluent. Blood flow distribution and the impact force acting on the robot by the impulsive blood flow have been simulated and calculated. All the results will provide strong proofs for the structure design and motion control of the micro robot.
