Hydraulic Levelling Control System Technology of Brick-Laying Robot

The article presents a hydraulic control system for the auto-levelling of a mobile bricklaying robot platform. To stabilize the position of the robotic bricklaying system, four extendable hydraulic supporting legs were used. For the correct operation of the robot, its horizontal position is important. To control the self-levelling process, the system uses a two-axis tilt sensor and proportional directional control valves. After the target practical test, the results show that this method is a simple and reliable adjustment and perfectly realizes the precise and fast levelling of the hydraulic platform of the bricklaying robot. It can also be used for other multi-point automatic levelling systems.
