ABSTRACT:
Objects contacted by mechanical fingers cause shunts that are touched at a position to contact resistance strips. Sensing resistance remaining between the shunt contact and one end of the resistance strip indicates position of contact along the finger. Shapes and alignments of objects are sensed by comparing positional information along several fingers.
