Suction Grinding Robot for Walls, Ceilings, and Complex Surfaces

The patent introduces a suction device that generates negative pressure to counteract the gravitational force acting on the grinding robot. This suction force acts as an anti-weight mechanism, enabling the robot to adhere to vertical and ceiling surfaces where dead weight alone would be insufficient. The suction device compensates for the weight force parallel to the surface, allowing the robot to maintain contact pressure for effective grinding on various surface orientations.

The grinding robot is equipped with a movement device that enables autonomous navigation and positioning on complex surfaces. The robot can independently adjust its position, orientation, and contact pressure using the suction device and movement mechanisms, eliminating the need for continuous manual guidance. This self-service capability allows the robot to handle complex geometries automatically while maintaining high surface finishing quality and significantly improving grinding efficiency.

The patent replaces the manual mechanical handling system with an automated robot system equipped with suction-based attachment and autonomous movement capabilities. Instead of relying on human operators to manually position and guide a heavy giraffe sander, the robot autonomously navigates the surface, maintains contact through suction force, and performs grinding operations. This substitution eliminates user effort while enabling coverage of large wall surfaces and complex geometries that would be difficult or impossible to reach manually.
