Stair case cleaning robot: Design considerations and a case study

Using robots for cleaning surface, glass, rooms etc. are not new and are in the field of research for more than a decade. But when it comes to stair case cleaning, we see that the research area is only few years old. The main reason is the enormous difference is design mechanism when it comes to vertical climbing robots compared to the robots that move over surface. These robots function in 3-D space where as surface cleaning robots function in 2-D space which is comparatively easier to design and implement compared to the 3-D space robots. In this work, we present various design considerations for vertical climbing robots to be used in stair case cleaning. We also present a case study with the design of one such robot that functions in 3-D space, the implementation, the testing, and the performance. The test results are very encouraging for a possible good quality design outcome which can serve the intended purpose.
