ABSTRACT:
A manipulator robot, particularly for transferring sheet metal elements from one pressing station to the next pressing station of a pressing line, includes a manipulating arm articulated to a base structure which is rotatably mounted for swivelling about a vertical axis on one end of a support lever the opposite end of which is rotatably mounted above a vertical axis on a fixed base. Electric drive motors are provided for effecting rotation of the support lever and of the base structure of the manipulating arm at speeds having a controlled ratio to each other and in opposite directions so as to move the element to be conveyed along a desired path at any desired speed and acceleration. An element pickup device is secured to the free end of the manipulating arm by means of a wrist joint which allows the pickup device to rotate about a longitudinal and a transverse axis of the manipulating arm.
