Control method and apparatus for rotation of side brush, and storage medium and electronic apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning apparatuses, such as sweeping robots, face challenges in accurately controlling the rotational speed of their side brushes, leading to inefficient cleaning due to either knocking away small obstacles at high speeds or inadequate cleaning at low speeds.
Innovation Solution
A method and apparatus that dynamically adjust the rotational speed of the side brush based on the working mode and detected obstacles, using size and type information to determine optimal speeds for effective cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the side brush rotation is controlled only by wheel rotation speed, then the control system is simple, but the side brush cannot adapt to different operating states (walking vs. cleaning) leading to poor cleaning performance or excessive wear
Solution Approach 1:
The side brush rotation control is changed from a static relationship (fixed ratio to wheel speed) to a dynamic control system that adjusts rotation speed based on real-time detection of operating state. The controller dynamically modifies the rotation speed according to whether the robot is walking or cleaning, enabling adaptation to different operating conditions while maintaining a relatively simple overall system architecture.
2Reliability
If the side brush rotates at high speed during walking, then the brush is ready for cleaning, but energy is wasted and the brush wears prematurely
Solution Approach 1:
The side brush is rotated at a first (lower) speed during walking to maintain basic readiness without excessive rotation. The system performs preliminary preparation by keeping the brush rotating at a moderate level, sufficient for its function but conserving energy and reducing wear. When cleaning mode is detected, the rotation speed increases to the second (higher) speed for optimal cleaning performance.
3Productivity
If the side brush rotation speed is not adjusted during cleaning, then the control system remains simple, but cleaning performance deteriorates when wheel speed changes
Solution Approach 1:
The controller continuously monitors the operating state (walking or cleaning) and adjusts the side brush rotation speed accordingly. During cleaning operations, the system detects when the main wheel rotation speed changes and automatically adjusts the side brush speed to maintain optimal cleaning performance. This feedback mechanism ensures consistent cleaning effectiveness across varying operating conditions while keeping the control logic relatively straightforward.

AI summary
Method, apparatus, storage medium, and electronic device for controlling rotation of a side brush are provided. The method may include obtaining a working mode of a cleaning apparatus when the cleaning apparatus is working (S202); determining a target rotational speed of the side brush of the cleaning apparatus according to the working mode of the cleaning apparatus and information of an obstacle detected by the cleaning apparatus in an area currently being cleaned (S204); and controlling the side brush of the cleaning apparatus to rotate at the target rotational speed (S206). The problem of low accuracy of controlling the rotational speed of the side brush by the cleaning apparatus in the related art is solved, thereby realizing the effect of improving the accuracy of controlling the rotational speed of the side brush by the cleaning apparatus.
