Abstract: A robotic system for a robotic limb configured to recover energy for minimizing power consumption of the robotic system, comprising a first support member, a second support member, and a quasi-passive elastic actuator rotatably coupling the first and second support members to define a joint of the robotic system rotatable about an axis of rotation defining a degree of freedom. The quasi-passive elastic actuator can comprise a first vane device and a second vane device, the first vane device and second vane device being rotatable relative to each other within the housing and defining, at least in part, a compression chamber and an expansion chamber. The system can further comprise a valve assembly, the valve assembly comprising a valve device disposed through an opening of the first vane device along the axis of rotation, and a shunt circuit facilitating fluid flow between the compression and expansion chambers through the valve assembly. The valve assembly is operable to position the valve device in an open position to open the shunt circuit to place the quasi-passive elastic actuator in an inelastic state, and to position the valve device in a closed position to close the shunt circuit to place the quasi-passive elastic actuator in an elastic state.

Abstract: A method of facilitating switching of a quasi-passive elastic actuator of a tunable actuator joint module of a robotic system between an inelastic state and an elastic state comprising configuring a quasi-passive elastic actuator to be operable with a primary actuator of the tunable actuator joint module to selectively apply an augmented torque to assist the primary actuator in rotation of a joint of the tunable actuator joint module. The method further comprises configuring an elastic component of the quasi-passive actuator to comprise a first vane device and second vane device rotatable relative to each other within a housing, supporting a valve assembly about the axis of rotation of the joint through the first vane device, and configuring a shunt circuit to facilitate fluid flow between compression and expansion chambers through the valve assembly. The method can further comprise configuring the valve assembly with a valve device disposed in an opening of a shaft of the first vane device, the valve device being actuatable between an open position to open the shunt circuit and a closed position to close the shunt circuit.

Abstract: A robotic end-effector comprises a pair of members being movable with respect to one another and a bladder on at least one of the members. The bladder can comprise a filler within the bladder. The filler can comprise a plurality of jamming particles and a plurality of elongate resilient spacers. The jamming particles are operable to flow within the bladder and to contact and engage with the elongate resilient spacers where flow characteristics vary within the bladder. The bladder with the filler can comprise at least two configurations: a compliant configuration in which a shape of the bladder and filler are changeable, and a stiff configuration in which change in shape of the bladder and filler are resisted.

Abstract: A technology is described for redundant network communication in a robot. An example of the technology can include a main robotic controller and a robotic component including a local controller and a controlled component that is operable based on a data signal comprising control instructions executed by the local controller. A command can be sent between the main robotic controller and the local controller. The command can be encoded in a first data signal and a second data signal. The first data signal can be sent over a first network channel, and the second data signal can be sent over a second network channel. The first data signal and the second data signal can be configured to be redundant data signals for the local controller sent respectively over the first network channel and the second network channel.

Abstract: A method for operating a robotic joint of a robotic system comprising selectively operating a clutch mechanism of a clutched joint module in an engaged state to cause a quasi-passive elastic actuator to enter an elastic state, the clutched joint module operating about and defining a joint of the robotic system. The method comprising effecting a first rotation of the joint to cause the quasi-passive elastic actuator to store energy during at least a portion of the rotation of the joint. The method comprising effecting a second rotation of the joint and causing the stored energy from the quasi-passive elastic actuator to be released in the form of an augmented torque applied to an output member of the clutched joint module. The method comprising selectively operating the clutch mechanism in a disengaged state to cause the quasi-passive elastic actuator to enter an inelastic state. The method comprising effecting a third rotation of the joint, wherein the quasi-passive elastic actuator facilitates a free swing mode of the clutched joint module and the joint.
