【Abstract】 A kind of driving mechanism of micro-robot utilizing the traction force produced by the rotation of screws was studied. The axial frictional pulling force and the minimum thickness of mucus film were analyzed and calculated in detail when rectangular or trapezoidal cylindrical screw was being adopted in microcomputer. Through comparing the parameters of moving characteristics of microcomputer with these two kinds of screws, the optimized structural parameters of microcomputer were obtained.更多还原
