ABSTRACT:
A robotic joint wherein an elongated support member attached at one end to a base has the other end thereof pivotally attached to one end of a lever, the other end of the lever extending away from the support member. A tension strip extends along the support member and over the other end of the lever, the ends of the tension strip being attached to the base on opposite sides of the support member. A pair of bladders positioned between the tension strip and the support member on opposite sides thereof can be inflated to apply a tensile force to the strip and cause the lever to pivot, carring with it a finger which is attached to the lever.
