A Control Method for Robot Fingers with Three-Axis Force Sensor

Abstract

This paper proposed a new grasping method for robot fingers with three-axis force sensors. When a robot hand with two fingers is grasping an object, such as an egg, two closed loops with negative feedback in force-control system are start. When grasping force of the two fingers are equal reference force, dynamic balance is reached. Once tiny sliding between egg and finger occurred, force feedback start immediately, dynamic balance is reached again. In this way, our robot hand can firmly grasps eggs, even if vibration added on the robot hand.
