A remote controlled demolition robot (10) comprising a controller (17) and at least one actuator (12) controlled through a hydraulic system (400) comprising at least one valve (13a) connected to a corresponding actuator for a tool (11b) and a pump (410). The controller (17) is configured to operate in a first mode wherein the fluid flow is controlled through the at least one valve (13a), wherein said valve (13a) is a proportional valve, receive a pressure indication indicating a pressure in the hydraulic system (400) and determine if the pressure in the hydraulic system (400) is above a first mode threshold and/or if a pressure change fulfills a first mode condition, and if so operate in a second mode wherein the at least one valve (13a) is in an opened state and the fluid flow is controlled through the pump (410).
A remote controlled demolition robot comprising a controller and at least one actuator controlled through a hydraulic system comprising at least one valve connected to a corresponding actuator for a tool and a pump, wherein the controller is configured to:
A method for operating a remote controlled demolition robot comprising at least one actuator controlled through a hydraulic system comprising at least one valve connected to a corresponding actuator for a tool and a pump, wherein the method comprises:
