Abstract: An enhanced actuator assembly, such as for use in driving a joint member of a wearable robotic device, is characterized by electrical isolation of the motor from the transmission system output. An actuator assembly includes a motor and a transmission system that provides a speed reduction of a motor speed to an output speed. The transmission system includes a non-conductive material layer that electrically isolates the motor from an output of the transmission system. The transmission system may be a two-stage transmission system. A first stage of speed reduction of the transmission system may include a first rotating member, such as a first helical gear, attached to the output shaft of the motor that transmits power to a second rotating member, such as a second helical gear. The second rotating member has a diameter larger than a diameter of the first rotating member to form the first stage of speed reduction, and the non-conductive material layer is part of the second rotating member.

Abstract: A joint actuator assembly incudes a motor, a rotating driving member driven by the motor for driving a driven component, and a transmission assembly located between the motor and the rotating driving member that provides speed reduction from the motor to the rotating driving member. The rotating driving member includes a magnetic/electrical coupling comprising a magnetic coupling component configured to magnetically couple with an opposing magnetic coupling of the driven component, and an electrical element configured to provide an electrical connection to an opposing electrical element of the driven component. The actuator and driven component may be combined into a mobility device including a magnetic/electrical coupling system comprising a first magnetic/electrical coupling on the actuator assembly that magnetically and electrically couples to a second magnetic/electrical coupling on the driven component.

Abstract: A joint actuator assembly for a legged mobility device includes a motor that drives a joint connector for driving a joint of the mobility device, and a three-stage transmission of speed reduction to result in a high torque, low speed output. The first stage may include a small sprocket mechanically connected to the output shaft of the motor, and a large sprocket driven by a cable chain to provide the first speed reduction. The second stage may include a small central helical gear mechanically connected to the first stage output, and two opposing larger first and second outer helical gears that mesh with the central gear to provide the second speed reduction. The third stage may include a cable reel assembly including an output reel and a cable element that interconnects the output of the second stage and the output reel to provide the third speed reduction.
