Each of the heads comprise an annular sector of the flexure hub, and the first and second stationary heads are interleaved between the first and second rotatable heads. The device may also include a stationary housing coupled to the first stationary head and the second stationary head of the flexure hub. The device may also include a first sensor positioned adjacent to the first rotatable head of the flexure hub, and a second sensor positioned adjacent to the second rotatable head of the flexure hub. The device may also include a rotatable housing coupled to the first rotatable head and the second rotatable head of the flexure hub.

Abstract: Examples described here include a device that has a housing defining a cavity, and a force sensor. The device also includes a first hydraulic actuator positioned in the cavity, and a second hydraulic actuator positioned in the cavity. The first and second hydraulic actuators move between respectively relaxing modes and thrusting modes along respective longitudinal axes. The longitudinal axis of the first hydraulic actuator is substantially parallel to the longitudinal axis of the second hydraulic actuator. The device also includes a first actuated member coupled to the first hydraulic actuator, and a second actuated member coupled to the second hydraulic actuator.

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 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).
