AI Technical Summary

Technical Problem

Existing wheeled stair-climbing robots suffer from problems such as insufficient power, poor climbing stability, inability to integrate cleaning components, and insufficient lateral movement performance in stairwell scenarios, making it difficult to meet the cleaning and position adjustment needs in complex environments.

Method used

Design a stair-climbing robot that uses two sets of climbing components and a horizontal drive component, combined with infrared sensors and control components, to achieve three separate vertical movements, enabling it to climb stairs smoothly and quickly, and achieve thorough cleaning by installing a vacuuming device.

Benefits of technology

It enables robots to climb and clean stairs efficiently and stably, and can flexibly and accurately adjust their position to complete the adsorption of garbage on stairs without dead angles. The structure is simple and reliable.

Abstract

The invention provides a stair climbing robot and a stair climbing control method thereof, and relates to the technical field of robots. Comprising a machine body, a first climbing assembly, a second climbing assembly, a control assembly and a power supply; the machine body comprises a frame body, two optical axis sets are vertically arranged on the frame body, and a climbing driving assembly, a frame body driving assembly and a clamping base used for installing a dust suction device are arranged at the bottom of the frame body; the first climbing assembly is connected with the machine body through one optical axis set, the second climbing assembly is connected with the machine body through the other optical axis set, and the first climbing assembly and the second climbing assembly can move in the height direction of the optical axis sets. The climbing driving assembly is used for controlling the first climbing assembly and the second climbing assembly to move; the first climbing assembly and the second climbing assembly are each provided with a horizontal driving assembly and a sensing assembly. The stair climbing robot is novel in structure, easy to control, high in stability and capable of stably, rapidly and efficiently achieving continuous lifting or descending of multiple steps and achieving the function of going up and down stairs.
