ABSTRACT:
A device for operating an articulated arm of a large manipulator connected to a boom base. The large manipulator comprises an articulated boom (22), composed of three boom arms (23to27), the boom arms of which may each be pivoted around mutually parallel horizontal articulation axis (28to32), in a limited manner. Furthermore, a control device (74), for the boom displacement is provided, which may be controlled from a remote controller (50) over a data transmission path (68). The remote controller comprises a first and a second remote control device (60, 62), each of which may be adjusted in at least one main control direction and thereby providing an output signal (64, 66), while the control device (74) comprises a computer supported coordinate transformer (80), responsive to the output signal (64) from the first remote control device (60), by means of which the drive units (34to38) for the redundant articulation axes may be operated in the one main control direction (r) of the first remote control device (60), according to the pattern of a pre-determined path-angle relationship. According to the invention, in order to match the boom configuration to differing operating tasks, the control device (74) comprises a correction routine (84) based on the output signal (66) from the second remote control device (62), by means of which the drive unit of a selected articulation axis may be preferably operated in one of the main operating directions of the second remote control device (62).
