Abstract
A telescopic manipulation arm includes a module formed by two segments and a toggle joint. All movements of the toggle joint are transmitted across the module by identical mechanisms in such a way that the friction and inertia are the same for each movement. These mechanisms incorporate shafts positioned equidistantly of an axis in the lower segment and shafts positioned equidistantly of the axis in an upper segment. Shafts are provided for carrying identical pinions, which engage on identical toothed gears, and which are also engaged on substantially identical pinions rotatable with the shafts.
