Manned stair-climbing robot and stair-climbing method thereof

Abstract

The invention discloses a manned stair-climbing robot. The robot comprises a chassis system, a driving system, a seat system, a buffer system and a control system. The chassis system comprises tracksand chain-type crawler belts, wherein driving motors are arranged on the chassis, one end of a seat is hinged to the chassis, the other end of the seat is in threaded fit with an adjusting screw, thebuffer system comprises a buffer motor, a buffer lead screw and a buffer supporting arm, buffer wheels are further arranged on the buffer supporting arm, and the control system is used for controllingthe rotating speeds and directions of the driving motors, an adjusting motor and the buffer motor. According to the robot, the chain-type crawler belts and the tracks are adopted, resistance is smallin the moving process, flat ground walking and stair climbing can be integrated, and a wheel-crawler mechanism is replaced. In order to prevent forward and backward overturning during stair climbing,a leveling buffer system is designed, and a buffer accurately connects the stair climbing machine to a slow-walking platform. The seat adjusting system is arranged, so that no matter how large the gradient of the staircase is, the seat is always kept in a horizontal state, and the riding comfort is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of stair-climbing machinery, and in particular relates to a manned stair-climbing robot and a stair-climbing method thereof. Background technique [0002] At present, nearly half of urban residents in China still live in buildings below 7 floors without elevators, and daily travel must first face the problem of climbing stairs. For young and middle-aged people, the burden is not big, but for the elderly or special groups, it brings great inconvenience. [0003] In order to cope with the above problems, a stair climbing machine has appeared, which can take people or wheelchairs upstairs. At present, there are many types of stair climbing machines in the market, including wheeled, rubber tracked, and wheel-tracked. However, the wheeled ones have poor balance, poor safety, and poor riding comfort during the process of going upstairs. It is easy to cause people in wheelchairs to fall from the wheelchair, and t...
