Abstract

Abstract: A reducer is designed for clamping mechanism to provide sufficient expanding force and the relatively slow expanding speed. The reduction ratio of the reducer is up to 489 to ensure a large output torque. In addition, the optimization experiment of the wireless power receiving coil is carried out. The influence of the dimension of the one-dimensional receiving coil and the number of winding wires on the receiving effiency is analyzed. The results show that the larger the core thickness is, the higher the receiving efficiency is, considering the total outer diameter of the core and the winding.

Key words: active gastrointestinal robot, clamping mechanism, reducer, wireless power receiving coil
