A motor driver is configured to control a motor output of at least one motor, the motor output coupled to at least one clutch input. A mode selector module is configured to receive signals representative of at least one movement parameter of the end effector, the mode selector module selecting a mode between at least the controlled slippage mode and the combined mode of the clutch driver based on the signals, and switching the selected mode based on the signals. A movement controller controls the clutch driver and the motor driver to displace the end effector based on at least one of the selected mode and on commanded movements of the end effector for the end effector to achieve the commanded movements.

摘要： An actuator system has a power source, an output member, a first fluidic coupling and a second fluidic coupling. The fluidic couplings generate a variable amount of torque transmission. A transmission operatively couples the fluidic couplings to the power source and to the output member in at least first load path and a second load path, the first load path and the second load path being parallel to one another, the first load path including the first fluidic coupling, the second load path including the second fluidic coupling. The fluidic couplings are operable for torque from the power source to be transmitted solely via the first load path, solely via the second load path, and cumulatively via the first load path and the second load path.
