Abstract: The present disclosure relates to a vehicular work machine (10) that is adapted for handling at least two different interchangeable tools (4). The machine (10) also comprises a user control device (11) and a water supply arrangement (31) that is adapted to distribute water for retaining dust that is created when a tool (4) is used, The water supply arrangement (31) comprises a controllable valve (24) that is arranged to control the flow of the water that is distributed via at least one nozzle (29). The user control device (11) is arranged for selection of a desired tool, where at least one selectable tool is associated with a certain predefined water setting. Each water setting relates to a certain relative flow of distributed water during a certain time that is related to the time said tool (4) is chosen and performing a certain work procedure, and/or to the time said tool (4) is chosen and ready to perform a certain work procedure.

Abstract: A remote demolition robot (10) comprising a controller (17), drive means (14), an arm member (11) movably arranged on a tower (10a) rotatably arranged on a body (11b) of the remote demolition robot (10) and a remote control (22) for providing commands, that are interpreted by the controller (17) causing the controller (17) to control the operation of the remote demolition robot (10), wherein the remote control (22) comprises a first joystick (24a) and a second joystick (24b), wherein the remote control (22) is characterized in that each joystick (24) is provided with a thumb control switch (26).

Abstract: A remote controlled demolition robot (10) comprising a controller (17) and at least one control switch (24, 25, 26) for providing a control signal that is received by the controller (17), wherein the controller (17) is configured to control the operation of a corresponding robot part (10a, 11, 14, 15). The controller (17) is further configured to: receive a pressure sensor reading from a pressure sensor (13b) for a proportional hydraulic valve (13a), said pressure sensor reading indicating a standby pressure; provide the control signal to the valve (13a); and increase a signal level of the control signal provided to the valve (13a) until a change in the pressure is detected; determine a starting offset for the valve (13a), said starting offset corresponding to the current signal level of the control signal.
