摘要
The micro-gripper is an essential device in micro-manipulation. A new micro-gripper fabrication process using MEMS technology is developed for a robotic micro-manipulation system. The mechanical stiffness of this gripper is analyzed with the Pseudo-Rigid Body Model to estimate the grip force of these micro-grippers of various scales and materials. The validity of the proposed model is verified by simulations and experiments. An experimental robotic micro-manipulation system consisting of this micro-gripper and a precision manipulator is implemented, and an actual gripping test is conducted to evaluate the robotic manipulation system.
