Abstract: Devices and systems for performing an operation are provided. The system comprises a mobile platform comprising a frame having side supports and a rear support, side wheel assemblies coupled to the side supports, and a rear wheel assembly coupled to the rear support. The wheel assemblies each comprise wheels and a wheel frame, the wheel frame being pivotally connected to the side and rear supports. The system further comprises a first control system for controlling movement of the mobile platform and a manipulator element coupled to the mobile platform. The manipulator element is configured to removably connect to the mobile platform and to perform an operation. The manipulator element comprises a second control system for controlling the operation. The first control system and the second control system are configured to communicate to cause the mobile platform to move and to cause the manipulator element to perform the operation.

Abstract: Devices, systems and methods of performing a surface operation on a building are provided. The device comprises a plurality of cables removably coupled to a surface of a building, tower or bridge, each of the plurality of cables removably coupled at a different position on the surface; and a body coupled to the plurality of cables at an intersection of the plurality of cables. A length of each cable between the respective position on the surface and the body is automatically adjustable and a tension in each cable is maintained to move the body on the surface. The devices, systems, and methods can be used on buildings, tower, or bridges with complex geometries or irregular surfaces to for example, automatically clean the surface of the building.
