Based on the locomotion principles of gastropoda,a novel interventional micro robot was presented,which has the ability to resist the attack of flowing blood.Based on the experimental data of healthy adults'artery near the heart,the simplified numerical models of the robot's operation environment were built.The main factors which affected the blood flow rate were analyzed.Also the ranges of the impulsive force produced by the blood stream when the robot operated in the arterial environment were calculated.According to the theoretical results,the needed friction forces applied to the robot's stationary unit were analyzed.All the researches will give the basis for the control of the micro robot.
