    Abstract: A robotic end-effector to provide conformal object interaction. The end-effector has at least one finger with an inner portion or engaging side and one or more degrees of freedom. A jamming conformal pad is on the inner portion of the at least one finger. The jamming conformal pad has a compliant configuration in which the jamming conformal pad is compliant and configured to distribute across a surface of an object and, if contoured, infiltrate into any variations (e.g., indentations) in the surface, defining a conformal engaging surface configured to match and mate with the surface. The jamming conformal pad has a stiff configuration in which the jamming conformal pad is stiff or relatively stiff as compared to the jamming conformal pad in the compliant configuration, and which substantially maintains a shape of the conformal engaging surface.

    Abstract: A clutched joint module comprising an output member and an input member rotatable relative to each other about an axis of rotation; a primary actuator operable to apply a primary torque to rotate the output member about the axis of rotation; and a clutch mechanism operable between an engaged state and a disengaged state to facilitate application of the primary torque. The clutch mechanism can comprise a plurality of plates and an actuator operable to compress the plurality of plates to cause the clutch mechanism to function in the engaged state. The actuator can be a ball-ramp clutch device. A quasi-passive elastic actuator can be coupled to the input member and can be operable, via the clutch mechanism, to release stored energy to apply an augmented torque to assist rotation of the output member. Associated methods and systems are disclosed.

    Abstract: A master robotic system for translating a force at a slave robotic system to the master robotic system comprises a plurality of master brake joints rotatably coupling a plurality of robotic links. Each master brake joint corresponds to a respective slave joint of a slave robotic system. Each master brake joint comprises a first braking component (e.g., sheet disk(s)) coupled to a first robotic link and a second braking component (e.g., sheet disk(s)) coupled to a second robotic link, and an actuator operable to act upon the first braking component and the second braking component, to generate a braking force between the first braking component and the second braking component, in response to a control signal corresponding to a sensed force sensed by the slave robotic system. The actuator can comprise a bi-directional actuator, or a cam, piezoelectric, dielectric, or hydraulic actuator, each having minimal power requirements to maximize the braking force of the master brake joint.

    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.
