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.
