The invention relates to a mechanically-electrically integrated home stairs porter robotics system which is driven by electric power, can go up and down the stairs and can carry heavy objects. The home stairs porter robotics system is composed of a driven running and steering system work chamber 3 at the upper part, a braced strut supporting frame system work chamber 4 at the middle part and an electric drive running controlling system work chamber 2 at the lower part. In China, stairs hand banisters composed of concrete iron, cement and wooden banisters are commonly installed in low buildings without elevators and below eight floors, and the home stairs porter robotics system uses and goes along the stairs hand banisters to trippingly go up and down the stairs. Senior citizens with inconvenience in walk or patients can sit on the robotics system conveniently to go up and down the stairs, and the robotics system can also carry hundreds of kilograms of heavy objects to go up and down the stairs, thus the mechanically-electrically integrated home stairs porter robotics system of the invention can be a piece of new equipment quite appropriate for removers, property management companies and construction companies.
