Abstract: A mechanism for polishing includes a polishing member, an eccentric member coupled to the polishing member, and a driving member coupled to the eccentric member. The driving member drives the eccentric member to rotate to move the polishing member to reciprocate in the one-dimensional direction, so that when a relative position between the polishing mechanism and the workpiece is fixed, the polishing member polishes a workpiece by translating a polishing surface. A method for the polishing process, applied by a polishing device, is also disclosed. By using the polishing mechanism, the entirety of the polishable surface of the workpiece can be covered, and collapsed edges of the workpiece are avoided.

Abstract: A toroidal actuator is responsive to a teleoperator for providing haptic feedback responsive to a curvature or articulated movement applied to a gripped object. The toroidal actuator surrounds an operator member such as a finger, and is responsive to pneumatic pressure for increasing telepresence force defined by resistance encounter against a teleoperated robotic claw. As the teleoperated claw grips an object, increased pneumatic pressure in the toroidal actuator tends to elongate the toroidal shape in a linear manner and oppose a curvature force applied by an inserted operator finger. Resistive force is based on soft sensing of the gripped object, thus the toroidal actuator applies an increasing resistive force to curvature as the robotic claw closes around a gripped object by solenoid regulated air pressure. A typical assembly includes at least 3 toroidal actuators for two digits and a thumb of an operator.
