Autonomous Mobile Robot Control Switching to Prevent Route Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous mobile robots, such as cleaning robots, often move along similar routes when operating in the same area, leading to inefficient cleaning due to the use of a single control algorithm, resulting in overlapping cleaning paths and reduced operational efficiency.
Innovation Solution
The implementation of an autonomous mobile apparatus that determines and switches between different control methods based on information from other robots, allowing each robot to use distinct algorithms for navigation, such as clockwise and counterclockwise routes, to ensure unique movement paths and improve operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single control algorithm is used for autonomous mobile robots, then the control system is simple, but the cleaning efficiency deteriorates due to overlapping paths
Solution Approach 1:
The patent applies dynamics by making the control algorithm selectable and changeable based on operational conditions. The autonomous mobile robot can dynamically switch between first and second control algorithms depending on the presence and actions of other robots, allowing the system to adapt its behavior for optimal cleaning efficiency while maintaining reasonable control complexity through structured decision-making rules.
2Adaptability or versatility
If multiple autonomous robots operate in the same area using the same control algorithm, then the deployment is simple, but the operational efficiency deteriorates due to route overlap
Solution Approach 1:
The patent implements feedback mechanisms where each autonomous mobile robot monitors and detects the presence, movement, and cleaning status of other robots in the same area. This feedback information is used to adjust the control algorithm selection, enabling robots to coordinate their paths and avoid overlapping routes, thereby maintaining high operational efficiency while allowing flexible multi-robot deployment.

AI summary
An autonomous mobile apparatus includes one or more memories and circuitry which, in operation, performs operations including determining a first control method or a second control method as a control method for controlling the autonomous mobile apparatus on the basis of information regarding another autonomous mobile apparatus, the first control method being a method for controlling the autonomous mobile apparatus or the other autonomous mobile apparatus such that the autonomous mobile apparatus or the other autonomous mobile apparatus autonomously moves in a certain area using a first control algorithm and the second control method being a method for controlling the autonomous mobile apparatus or the other autonomous mobile apparatus such that the autonomous mobile apparatus or the other autonomous mobile apparatus autonomously moves in the certain area using a second control algorithm, and autonomously moving the autonomous mobile apparatus using the determined control method.
