Design and analysis of artificial microrobot propulsion mechanism using multiple flagella

Nowadays, studies of the interventional microrobots have been hot topics in the field of medical devices. The ultimate goal of medical microrobots is to reach currently inaccessible areas of the human body and carry out a host of complex operations such as minimally invasive surgery (MIS), highly localized drug delivery and opening up the blood vessels. Miniature, safe and energy efficient propulsion systems hold the key to mature this technology. In this paper, a prototype of microrobot based on the motion principle of living microorganisms is presented. The properties of this propulsive mechanism are estimated by modeling the dynamics of the swimming methods. And to adjust the rotation direction of the four flexible tails, the propulsion forces and the function of opening up the blood vessels will be generated.
