Low cost implementation of pseudo arm by poly-finger tactual interface

This design presents a low cost implementation of an integrated polyfinger robotic arm equipped with a feedback sensor mechanism through strain gauge that is governed by discrete fuzzy algorithm. This work seeks to develop a robotic hand which can be combined with a high fidelity data glove interface to allow teleoperation tasks to be performed via wireless channel. So far we have successfully implemented our system on matlab and realized the position feedback of servo motor through NI labview for more accuracy. Since whole robotic arm “Chainfinger” is made from bike engine chain, simple dc motor and some feedback strain gauze and resistive sensor, it provide a low cost solution for disabled people and in hazardous environment as a commercial product.
