Abstract
In this paper, we carried out a series of experiments and evaluations Motion Performance for a Magnetic Actuated Screw Jet Microrobot. Our system consists of three main parts, the power supply section, 3-axes Helmholtz coils are to provide a uniform controllable magnetic field; the simulated intestinal part, a 450mm long φ20mm liquid filled pipe; a screw jet microrobot, it consists an O-ring type neodymium magnet and screw structure. We have verified in previous papers that our magnetic actuated screw jet microrobot can run smoothly in a variety of liquid environments (extra degree of freedom that enables various advanced functions such as axial position control), in the following discussion, we will keep the other conditions unchanged, to evaluate the influence of changing the pitch of the screw of the speed. There are many factors affecting the speed, we will also evaluate the effects of viscosity coefficient of different liquids on the velocity.
