ARTICULATION A ROTULE POUR BRAS POLYARTICULE

摘要

A ball-and-socket joint for a multiarticulate arm includes two cylindrical bodies forming phalanges each ending in a pair of jaws which contact a hollow sphere limited by two parallel planes essentially equidistant from the center of the sphere, with the hollow central part of the cylindrical bodies and of the sphere serving as a passage for the device for synchronizing the movements of the phalanges.
