A hexapod, for example, a hexapod used to position a tool with respect to a part to be machined, includes two spaced plates interconnected by six articulated and extensible legs. The two plates, including a base plate and a mobile plate, and the six legs are joined for varying, at will, the relative position of the mobile plate with respect to that of the base plate. The hexapod further includes a device for reducing and/or compensating for stresses on the elements of the hexapod, which can be a mechanical device, such as a jack, coupling a fixed surface with the periphery of the mobile plate and/or logic (in software) for defining at least one force-limiting criterion. |
