Embodiment Construction

[0039] Such as Picture 1-1 and Figure 1-2 As shown, the wheel-leg type multi-functional corridor cleaning robot designed by the present invention includes a spoke-type wheel set dual-purpose for leveling roads and climbing stairs; a wheel-leg combination mechanism is designed; rotating brush cleaning, rolling brush cleaning, and dust suction are designed. Cleaning integrated cleaning module; designed the lifting mechanism and translation mechanism used to control the operation of the cleaning device; designed the control system based on STM32. The change state of level road state and climbing stair state is shown in the figure.

[0040] In the present invention, the four wheels of the spoke-type wheel set are all composed of a ball bearing drive motor 23, two spokes 2, 3 and a thrust ball bearing 1 in the middle, and the outer spokes of the front wheel and the rear wheel are driven by the motor. 3 rotation, the wheel set can switch the shape of the wheel set according to the...

Abstract

The invention discloses a multifunctional wheel-leg type stair sweeping robot which solves the problems that an existing robot is short of intelligence, instable in climbing, insufficient in climbing ability, low in sweeping efficiency and the like in a stair region with a complex environment. The robot comprises a machine body, a front walking wheel, a rear walking wheel, a sweeping module and a control system. The sweeping module comprises a power device, a rotary brush arranged on the front portion, a middle rolling brush arranged in the middle, a dust collector and a trash bin, wherein the dust collector and the trash bin are arranged behind the rolling brush, and the dust collector is communicated with the trash bin. The robot is also provided with a horizontal movement mechanism and a lifting mechanism, wherein the lifting mechanism is mounted on the machine body, the horizontal movement mechanism is mounted on the lifting mechanism, and a sweeping mechanism is mounted on the horizontal movement mechanism. The wheel-leg type stair sweeping robot is reasonable in structure, stable in climbing, high in climbing power, good in operating performance, high in sweeping efficiency, simple and practical.

Description

Technical field: [0001] The invention belongs to the field of robots and automatic control, in particular to a corridor cleaning robot which can complete the cleaning work in complex environment areas such as corridors. [0002] Background technique: [0003] There has been quite a long history for the research on the stair-climbing robot, and the existing stair-climbing robots are mainly divided into following four types: planetary wheel type, crawler type, leg-foot type and parallel four-bar mechanism type. [0004] Planetary wheel type: Under the premise of satisfying certain terrain adaptability, the mobile robot can give full play to the advantages of flexible movement and simple control. However, due to the unreasonable structure of the traditional planetary wheel set, the efficiency is not high when climbing stairs, and the overall stability of the robot is stable during operation. Sex is hard to secure. [0005] Crawler type: Crawler type climbing mechanism is w...
