Hydraulic directional valve, with mixed series (S) and parallel (P) hydraulic circuit consisting of two or more sections and one logic switching element (E, E1, E2), characterized in that said logic element (E, E1, E2) in neutral position involves connecting the series channel (S) of said mixed series and parallel hydraulic circuit with the branch downstream of pressure (P1), and at the same time isolates the pressure channel (P) of the parallel circuit and the discharge (T); when switching the distributor, the latter reaches a second position, which involves closing the channel (S) and simultaneously opening the parallel channel (P) towards the branch downstream of pressure (P1), and in this case channel (S) is set to discharge by the connection with (T); a control channel (1) copies the signal from the pressure channel (P) bringing it on one side of the logic element (E, E1, E2).

| This disclosure includes hydraulic apparatuses and methods for redundant actuation of a hydraulic device. Some apparatuses include a hydraulic device having a first hydraulic actuator and a second hydraulic actuator, wherein each of the first and second hydraulic actuators comprises at least a first hydraulic cavity, a second hydraulic cavity, and a piston. Some apparatuses also include a controller coupled to the hydraulic device. In some embodiments, the controller is configured to receive hydraulic fluid from a fluid source via at least two parallel hydraulic lines coupled to the controller, select a first hydraulic line of the at least two parallel hydraulic lines, and transfer the hydraulic fluid from the selected first hydraulic line to a first cavity of the first hydraulic actuator to apply pressure to a first piston to actuate the hydraulic device. | ||||||

| 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). | ||||||
