Abstract
An artificial skeletal mechanism having a central rigid inverted T-shaped link and a pair of elastic tubular actuators on either side of the link, each actuator having an inner chamber for receiving a pressure fluid serving to pretension it. Each actuator has one end articulated to one end of the cross bar of the T so that they are antagonistically pretensioned. The artificial skeletal mechanism is intended to transform the contraction of one actuator, following extension of the other, into rotation of the link which is articulated at the free end of its long bar.
