A multiarm automatic manipulator robot structure includes a fixed location support 10 which carries three locational arms 12, 14, 16, being hingedly connected to each other at their location of convergence to support a workhead 20, the screw type driving means 12a, 14a, and 16a each being independently operable to drive its respective arm in an axial direction, each of the arms being rigid in the sense that no part of the arm is hingedly connected to another part, so that the forces derived from a payload weight subject the arms primarily only to compression or tension. |
