Robot Hand with a Sensor of Cloth Handring

Abstract

A robot or robot system is regarded as a general-purpose machine system that, like a human, can perform many tasks under conditions un-known a priori. In this paper, it was showed that a robot hand to handle pieces of cloth was manufactuerd for trial and plural functions of the hand was studied experimentally. The results obtained were as follows.(1) The robot hand was able to separate a piece of cloth (about 0.5mm in thickness) from a stack of pieces of cloth.(2) The output signal from the strain guage of the hand was considered to be nearly in proportion to the thickness of pieces of cloth (0.1 mm3.0mm in thickness, under a pressure of 2.5N/cm2) held by the hand and by the signal, it was possible to distinguish thickness of the pieces of cloth.(3) The tension of a piece of cloth could be controled between 0. 0 9-0.12N by the arm and the hand.
