ABSTRACT:
An articulation for a manipulation arm at one end of which a tool, e.g. a spray gun, is to be mounted has two supporting elements such as plates or rings which are intercoupled by connecting rods, and joints between the connecting rods and the supporting elements have at least two degrees of freedom. A preferred number of rods is three, and two of the joints may be pivotally mounted to one of the supporting element but a third is non-rotatably mounted. By independent angular driving of two of the coupling rods a wide range of articulation displacements may be caused as between the supporting elements and hence communicated to a tool mounted on one of them. Furthermore the attitude of the tool about an axis perpendicular to the ring may be controlled by a rotatable drive rod linking pivots disposed centrally of each supporting element.
