Abstract
An apparatus for moving an operating head automatically through programmed functions using a telescoping arm assembly. The operating head and arm assembly are mounted on a base and are normally capable of motions about or along several axes, including linear extension and retraction relative to the base. The telescoping arm assembly includes a main carriage mounted on the base, an intermediate carriage mounted on the main carriage, and a head carriage supporting the operating head and mounted on the intermediate carriage for telescoping movement relative to the main carriage. The operating head is connected to the head carriage by a wrist joint for pivotal movement about a wrist tip axis, and even for additional rotary movement about a wrist roll axis, the control of the respective movements being accomplished for example, by chain and sprocket mechanisms in order to control the wrist movements continuously, even during the telescoping extension and retraction movement of the carriages.
