Design and Development of Low-Cost Three Degree of freedom Force Sensor

This paper describes a force sensor using metallic piezoresistive transducer for measuring the force originated by the physical interaction of the rigid body or arm incorporated autonomous vehicles in x, y and z co-ordinates [Fx, Fy and Fz]. It explains a theory, design and construction of single axis and multi-axis force/torque sensor. Here presents a novel idea for design a three degree of freedom force sensor which has wide application in the area of robotics, automation system and medical equipment. This force sensor has robust, low-cost, and small in size, easy to manufacture. It impedes the equipment from the damage. Used ANSYS software to analyze stress and strain of aluminum elastic body. Then practically implemented the design for verification of results.
