The toolholder head has two degrees of freedom of pivotal movement. The tool supported thereby is centered in a fixed point of focus irrespective of the position of the toolholder head and the tool can be adjusted without changing this point of focus merely by adjusting the toolholder head without adjusting other axes of movement of the robot.</p> |
