Abstract
A powered exoskeleton device includes an external frame, operable to be secured to a limb of a user. An artificial joint body pivotal about a joint axis is connected to the external frame to transmit force through the external frame to the limb of the user. A transmission transfers force from an input motor to the artificial joint body. The transmission includes a crank, pivotally coupled to the artificial joint body about a crank axle rotatable about a crank axis. A primary compression spring is carried by the artificial joint body and is operably coupled to the crank. Movement of the input motor results in the crank transferring force to the artificial joint body about the crank axle and through the primary compression spring to cause the artificial joint body to pivot about the joint axis, thus aiding the user is moving the limb.
