Triangular wheel train stair climbing vehicle

Abstract

In order to overcome the defects in the prior art, the triangular wheel train stair climbing vehicle is provided. A triangular wheel type robot is adopted, and a transmission system is stable in operation, low in noise, safe, reliable, not large in overall size and small in weight; each system is independently driven, and the control is flexible and convenient; a triangular wheel train type systemis adopted, so that the stair climbing vehicle can move in various environments, and the movement on the flat ground, the slope surface and the step surface can be easily realized; the stair climbingvehicle adopts an independent steering system, so that the turning radius is reduced, and turning in a narrow space is facilitated. The triangular wheel train stair climbing vehicle provided by the invention comprises a frame control part, a triangular wheel part, a sliding platform part and a bearing supporting part. A triangular support module in the frame control part is connected with a central shaft in the triangular wheel part, a stable tripod in the frame control part is connected with a support plate in the sliding platform part, and a traction rod in the sliding platform part is connected with a support frame in the bearing supporting part.

Description

technical field [0001] The invention relates to the field of mobile robots, in particular to a triangular gear train stair climbing vehicle. Background technique [0002] Due to physical reasons, it is inconvenient for the elderly to travel. Taking public transportation and other means of travel is very crowded due to the number of people, which is easy to cause physical injury. Some balance cars designed now are difficult to operate and require too much balance of the human body, so they are not suitable for the elderly. , In addition, it can only be used on flat ground. We designed a stair climbing planetary wheel balance car for the elderly, which has a high safety factor and is easy to operate. It can help the elderly climb stairs, which greatly facilitates the elderly to travel. In recent years, with the vigorous development of computer technology, the speed of calculation and data transmission has been greatly improved. Based on this hardware, many intelligent algorit...

AI Technical Summary

Problems solved by technology

and wear resistance are poor

Although the pneumatic wheel has good driving stability and obstacle-surmounting ability, its environmental adaptability is poor, so it cannot be applied to the stair climbing vehicle

Metal elastic wheels have good climbing performance, wear resistance, environmental adaptability, mechanical reliability, and obstacle-crossing ability, but their steering performance is poor.

Elliptical wheels, hemispherical wheels and hubless wheels have good climbing and obstacle performance and wear resistance, but their driving stability is poor and their mechanical reliability is the lowest.
