The present invention provides a remote control and a rocker device thereof, wherein a torsional spring is sleeved on each of a first rotating device and a second rotating device. When a handle is operated along a left-right direction of the X axis, the handle drives the second rotating device to move, and two legs of the torsional spring on the second rotating device are limited by a limiting block to generate reverse torsion. When the handle is released, the second rotating device resets under the action of the reverse torsion of the torsional spring, to bring the handle to the neutral position. A similar process is used for an operation along the Y axis. When the handle is operated along a direction other than the X axis and the Y axis, the handle drives the first rotating device and the second rotating device to move at the same time.

A magnetic locking actuator for a prosthetic or orthotic device is provided. The actuator includes a first component including one or more magnets and a second component including one or more magnets. The first and second components are coupled to separate portions of the device. The magnets allow for adjustment of a length of the actuator to adjust an angular orientation of the first and second portions of the device. When magnets in the second component are aligned with magnets in the first component having an opposite polarity, a position of the second component is fixed relative to the first component, locking the actuator. When magnets in the second component are not aligned with magnets in the first component having the opposite polarity, the position of the second component is adjustable relative to the first component, thereby allowing adjustment of the height of the actuator.
