DESC:FIELD OF THE INVENTION
The present invention relates to the field of robots. More specifically, the present invention relates to the field of an automated wall climbing robot.

BACKGROUND OF THE INVENTION
Applications over any high wall surface including buildings, apartments has its own priorities. Applications such as construction, painting, window cleaning, advertisement banner hosting and the like requires skilled labours and practical on-site experience for such duties. Most of the buildings and apartments are above ten storey high and requires atleast four to six labours to execute a single operation. Furthermore, most of labours requires high end equipments to do such operations.

Most experienced professionals uses ropes and temporary hooks fixated on the buildings to do works such as cleaning windows, painting, fixing banner frames and the like. Moreover, while executing such operations, safety of labours are still uncertain and carrying heavy equipments seems impossible. Furthermore, fixing such tools over plain wall surfaces may leave cracks and irregular marks over wall surfaces, and such operations are impossible if the buildings are glass finished window surfaces.

To resolve the above said issue many existing inventions are developed to provide safety and facility to labours. Such existing inventions may provide a solutions to the above said issue and are referred in the prior art section. Patent application CN208391864U describes a fixture for wall holding applications. Said invention proposes a locking mechanical means to attach over side wall surfaces and provides a support for holding machine applications. The invention clearly explains a stationary holding apparatus and did not propose any lifting means to carry equipments. Moreover, the invention did not propose any automation based climbing apparatus over any flat surfaces.

United States patent application USD692898 describes a circular mount for flat wall surfaces. Said invention is a circular type fixture which can be temporarily fixated on the wall surfaces. The invention clearly states that a stationary circular fixture is fixated on flat wall surfaces, but the invention did not propose any automation based climbing apparatus and did not propose any lifting means.

Indian patent application 201937013599 describes a plate holding apparatus to support objects and apparatus. Said invention is fixated on flat surfaces preferably over walls using clamps. Even though said invention proposes a holding apparatus, it did not propose any dynamic based weight lifting means. Furthermore, the invention did not convey any automated machines for carrying equipments.

Even though there are fixtures and locking apparatus in existing inventions, there are no inventions proposed in the field of automated robot for carrying and lifting equipments. Moreover, there are no effective automated based climbing robot proposed for carry heavy equipments over flat wall surfaces. Therefore the present invention proposes a flat surface climbing robot which utilises suction cups and pressure valves. Furthermore, the present invention also proposes an automated lifting means for carrying weighted objects over the flat surfaces easily and effectively.
