Mechanical arm system for maintaining building facade with irregular facade

Abstract

The invention provides a mechanical arm system for maintaining a building facade with an irregular facade. The mechanical arm system includes a platform connected to at least four pairs of cables that place the platform at a distance from the building facade; at least one mechanical arm located on the platform, wherein each mechanical arm further comprises an adapter located at the far end of the mechanical arm, and each adapter is used for fixing and manipulating a building facade maintenance tool; an actuator for driving the cable to move the platform to any position along the building facade; and a controller connected with the actuator, wherein the controller is used for indicating the actuator to drive the cable and controlling the movement of the mechanical arm. Any position deviation on the platform can be compensated through positioning or moving of the mechanical arm.

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 948,778, filed December 16, 2019, and U.S. Non-Provisional Application No. 17 / 120,302, filed December 14, 2020, the disclosures of which are incorporated by reference into this article. technical field [0003] The present invention generally relates to a robotic arm system for building facade maintenance operations. More specifically, the robotic arm system has a platform that includes one or more robotic arms mounted on the platform that can be used for cleaning windows and / or exterior walls, repairing, or painting with various tools. Background technique [0004] Operations on building facades such as cleaning windows and painting are expensive and dangerous operations for the construction industry. For high-rise buildings above thirty stories, the most common method of operation is a rope or gondola based system, or by using ropes / cables to t...

AI Technical Summary

Problems solved by technology

There are two parts to be aware of with such existing exterior maintenance solutions: First, these methods often involve spraying water, using paint, or rolling brushes, but these techniques have not been widely accepted by the construction industry because they do not adequately clean or paint building surfaces

Second, such mobile robotic arms can only operate well on flat or near-flat surfaces, on more complex surfaces or when building facades have any prominent features (e.g. box windows, oriel windows, and curved glass walls) are difficult to perform
