Abstract: A length adjustable robotic limb comprises a first joint assembly, a second joint assembly, and a structural member extending between the first joint assembly and the second joint assembly, the structural member defining a longitudinal axis. An adjustable interface can be provided between the structural member and one of the first and second joint assemblies. The adjustable interface can facilitate adjustment of a length between the first and second joint assemblies. A rotational interface between the structural member and one of the first and second joint assemblies can facilitate relative rotation between the first joint assembly and the second joint assembly about the longitudinal axis in a degree of freedom corresponding to medial/lateral rotation of a portion of a human limb.

Abstract: A robotic joint system is provided that facilitates efficient movement of a ground-contacting robotic system, such as during a gait cycle. The robotic joint system can comprise a first support member, a second support member, and a joint assembly rotatably coupling the first support member to the second support member about an axis of rotation. The joint assembly can comprise a passive actuation system coupled between the first and second support members. The passive actuation system can comprise a passive actuator operable to store energy and to release energy to apply a torque to the joint assembly and the first and second support members, and a length adapter coupled to the passive actuator operable to selectively direct the output of the stored energy of the passive actuator.

Abstract: A robotic joint system with integrated safety can include a first support member, a second support member, and a tunable actuator joint assembly including a joint having an axis of rotation about which the first support member and the second support member rotate. The tunable actuator joint assembly can include a primary actuator and a quasi-passive linear pneumatic actuator coupled between the first and second support members. The quasi-passive linear pneumatic actuator can comprise an active state in which the quasi-passive linear pneumatic actuator stores energy upon a first rotation of the first and second support members and releases energy upon a second rotation of the first and second support members opposite the first rotation, and an inactive state that facilitates return of the first and second support members to a default position.
