Adaptive control of hydraulic tool on remote controlled demolition robot
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).
