Mobile Robot Position Tracking for Cooperative Multi-Robot Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in coordinating the operation of multiple mobile robots within an area, particularly in ensuring they operate in conjunction without collisions and effectively performing different cleaning tasks like dry and wet cleaning.
Innovation Solution
Mobile robots use position confirmation methods, including marker irradiation and signal transmission, to calculate and follow the position of other robots, allowing them to cooperate and clean efficiently without collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed pointer is used to determine robot position, then position determination is simple, but multiple robots cannot operate in conjunction with each other
Solution Approach 1:
The pointer is changed from a fixed position to a movable one that follows the leading robot. This dynamic adjustment allows the pointer to continuously indicate the position of the leading robot, enabling the following robot to track and maintain a predetermined distance while allowing cooperative operation between multiple robots.
2Ease of operation
If a user moves the pointer to guide robot position, then robot can move to specific position, but it is difficult to apply to multiple robots and absolute position cannot be confirmed
Solution Approach 1:
The leading robot automatically becomes the moving pointer for the following robot. The leading robot's position indication function is utilized by the following robot for positioning, eliminating the need for separate user-controlled pointers for each robot and enabling automatic cooperative positioning.
3Productivity
If multiple robots operate independently in an area, then each robot can perform its function, but collisions occur and cooperative cleaning is not achieved
Solution Approach 1:
The following robot continuously detects the position of the leading robot through the moving pointer and adjusts its position to maintain a predetermined distance. This feedback mechanism ensures that the following robot stays at a safe distance from the leading robot, preventing collisions while enabling cooperative operation.

AI summary
In a mobile robot and a control method therefor according to the present disclosure, a plurality of mobile robots located in an area confirm the positions of other mobile robots and operate in cooperation with each other to cooperatively clean then area. One mobile robot moves to follow the position of another mobile robot, so that the mobile robots with different cleaning types cooperate to clean the area. Accordingly, the plurality of mobile robots can cooperatively perform cleaning without colliding within one area, and by combining or changing a plurality of position detection methods as needed, the position of another mobile robot can be easily calculated and the cleaning efficiency is greatly improved.
