STAIR CLIMBER ROBOT AND ITS WORKING PRINCIPLES

A robot that can effortlessly climb up and down stairs, as well as easily traverse uneven terrain, Stairs have traditionally been something of a nemesis to robots, and there is considerable footage of robots failing in the attempt, resolving this issue, allowing robots’ domain to expand beyond the ground floor, the ability to climb stairs and navigate human environments has been a major challenge for mobile robots, Traditional approaches of tackling this problem are too slow, require complex controls, and are too expensive for most applications.

A robot which moves freely in a building has to be adapted to an environment made for humans. On its way it may encounter small obstacles (up to 4 cm of height, e.g. door steps, sills etc.) and stairs. These stairs often have nosings or ledges and sometimes open risers. The slope of indoor stairs can vary between 25° and 42°. Sometimes you will find in residential buildings even steeper stairs, especially spiral stairs. In public buildings stairs often have a rise s of 17cm and a run a of 29cm (slope approx. 30°)

Wheeled rovers are the optimal solutions for well structured environment like roads or habitations. But off-the road, their efficiency is very dependent on the typical size of encountered obstacles that have to be overcome in a standard Motion mode. Which can typically overcome obstacles of their wheel size, if friction is high enough. Adding real climbing abilities to a wheeled rover requires the use of a special strategy and often implies dedicated actuators or complex control procedure.

The stair climber will be more helpful to the handicapped and worker because the wheelchair handicapped people used and the worker which they used the trolley are very limited in mobility. Besides, lots of budget is spent in construction to work out a special path. Sometimes it is hard or even impossible to build a path for old existing buildings. Thus, regular wheelchairs and trolley have problem entering these buildings. A stair climber which will help handicapped and workers to go over obstacles and staircase
