RESEARCH AND DESIGN OF THE MICROGRIPPER WITH RELEASE ADHESIVE OBJECT BASED ON VIBRATION

Abstract

Pick and place task are largely widespread operations in the industrial world, especially in micro world. At these scales, surface forces become dominating in comparison with volumic forces. Microgripper help the human do the task in the tiny world. The paper presented a gripper capable of autonomous release of micro objects. Release of adhered micro objects is achieved by vibration of end effectors. The vibratory motion of the end effectors is attributed by an impact bar embedded in a bistable mechanism. External force was applied to operate the gripper. Exploitation the bistable mechanism behaviour, the gripper requires no power input during gripping of objects. The compliant mechanism of the gripper help limitation the friction
and wear for its operation.
