Abstract (en)
The invention concerns a control system for a remote-controlled working machine (1) equipped with a manoeuvrable arm (10), in particular a demolition robot for demolition work, that is intended to carry at the free end of its arm a tool (14, 16), whereby the control system comprises a control unit (4) intended for the remote control of the working machine, whereby an operator (3) is in connection, either by cable or wirelessly, with a control computer (25) that is a component of a hydraulic control circuit (22) for the working machine, and which control unit includes a pair of control sticks (4a, 4b) and associated buttons and knobs that through their influence allow the working machine to be switched into different functional or working modes, whereby the manoeuvrable arm can be caused to carry out desired motions through a number of operating means (31, 32, 33, 34) that are driven hydraulically, that are arranged at the manoeuvrable arm, and that can be influenced by means of the said control sticks (4a, 4b). For an improved efficiency and ease of use, the working machine (1) can be switched through the control unit (4) between two different working modes, including: a first mode for manual operation in which the operator (3) controls the motion of the manoeuvrable arm (10) through direct influence of the relevant control sticks (4a, 4b) of the control unit (4), and a second mode for semi-automatic or fully automatic operation in which the operator (3), on influence of any one of the control sticks (4a, 4b), causes the manoeuvrable arm to move following a predetermined course through the synchronised control of at least two of the operating means (31, 32) of the manoeuvrable arm following a valve control curve (26a, 26b) for each one of these and stored as software in the control computer (25).
