    Abstract: An example robotic joint may include a first cam and a second cam. The robotic joint may also include a first actuator configured to contact the first cam, a second actuator configured to contact the first cam, a third actuator configured to contact the second cam, and a fourth actuator configured to contact the second cam. The robotic joint may also include a first coupling link configured to couple the first cam to a first drive shaft link, and a second coupling link configured to couple the second cam to a second drive shaft link. The robotic joint may also include a drive shaft rigidly coupled to the first drive shaft link and the second drive shaft link, wherein the drive shaft rotates about a first pivot axis when the first and third actuators and the second and fourth actuators act in concert.

    Abstract: The present disclosure relates to a system that uses linear actuators to generate a torque on a shaft. In an example implementation, a system may include a shaft and an attached cam. The cam includes an involute portion. The system also includes a first linear actuator and a second linear actuator configured to move along a first axis and a second axis, respectively. The linear actuators are configured to detachably couple to the cam based on at least a reference angle of the shaft. That is, as the shaft rotates about its rotational axis at the reference angle, the first and the second linear actuators may couple to, and decouple from, various portions of the cam. As the linear actuators couple to, and decouple from, the various portions of the cam, different rotational torques and/or different ranges of such torques may be imparted onto the shaft.

    Abstract: Example joints for a robotic device are provided. An example robotic joint may include an upper portion, a lower portion, and a connecting link positioned between the upper portion and the lower portion. The upper portion may be coupled to the connecting link via a first revolute joint, and the lower portion may be coupled to the connecting link via a second revolute joint. The robotic joint may also include an actuator having a first end coupled to the upper portion and a second end coupled to the connecting link, where the actuator is configured to apply a torque to the connecting link. The robotic joint may also include a coupling element configured to transfer the torque applied to the connecting link into a rotational motion of the lower portion about the second revolute joint.

    Abstract: Example embodiments may relate to a robotic system that includes a hydraulic actuator and an electric actuator both coupled to a joint of the robotic system. Operation of the actuators may be based on various factors such as based on desired joint parameters. For instance, such desired joint parameters may include a desired output torque/force of the joint, a desired output velocity of the joint, a desired acceleration of the joint, and/or a desired joint angle, among other possibilities. Given a model of power consumption as well as a model of the actuators, the robotic system may determine operating parameters such as hydraulic and electric operating parameters as well as power system parameters, among others. The robotic system may then control operation of the actuators, using the determined operating parameters, to obtain the desired joint parameters such that power dissipation in the system is minimized (i.e., maximizing actuation efficiency).
