This technology is a horizontal mobile unit consisting of first and second horizontal mobile modules, each equipped with a frame and a rail-moving component, connected by a vertical axis to allow for pivoting movement along horizontal rails installed on a building's exterior.
Painting, cleaning, and inspection of skyscrapers have traditionally relied on rope access or gondolas, exposing workers to fall risks from strong winds and gusts, while also resulting in significant variations in quality and cost based on worker skill. Existing exterior wall robots that use suction pads or magnets to adhere to walls require separate safety devices to prevent falls in case of malfunction and struggle to adapt to diverse curtain wall structures.
This technology connects two frames with a hinge and uses a restoring mechanism to straighten the modules, allowing them to travel continuously along curved rail sections. Each module features wheel units and drive components that follow the upper and lower rails, while guide wheels in the rail grooves and damper units between plates prevent derailment and absorb deviations. Applicable to skyscraper cleaning, curved curtain wall painting, and maintenance of non-standard buildings, this system eliminates fall risks from suction failure and enables autonomous operation on curved facades.
This invention was developed with support from the Korea Agency for Infrastructure Technology Advancement for the development of Built-in Guide type mobile/work mechanisms and platforms.
