Abstract
An articulated mechanism for use as an articulated arm of an industrial robot, for example, includes a plurality of arms interconnecting articulations having respective fluid pressure angular displacement motors for angularly displacing the arms relatively to each other. The motors have sidewalls forming working chambers, where an inner surface of the sidewall is exposed to working fluid pressure tending to bow the sidewall outward, and an outer surface of the sidewall has a plurality of counteracting pressure chambers which apply a counteracting pressure force against the sidewall to oppose the outward bowing force, the counteracting pressure force increasing in pressure surface area as the piston is displaced within the motor chamber.
