Mobile Robot Light Signaling for User Operation Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing control systems for mobile robots that can autonomously move, users may fail to notice when their operation is either desirable or not, leading to inappropriate or delayed actions.
Innovation Solution
A control system that uses a light emission unit to emit different light patterns based on predetermined conditions, recommending or not recommending user operations, allowing users to visually recognize when their intervention is necessary or unnecessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile robot operates autonomously without visual indicators, then the device complexity is reduced, but the user cannot promptly notice when operation is desirable or not desirable
Solution Approach 1:
The patent applies color changes through a light emission unit that displays different colors (e.g., green for desirable operation, red for not desirable) to provide intuitive visual feedback to users about whether their operation is appropriate, thereby improving user awareness without significantly increasing system complexity
Solution Approach 2:
The light emission unit serves as an intermediary between the autonomous mobile robot system and the user, translating complex system states into simple visual signals that indicate whether user intervention is desirable, thus bridging the information gap without requiring direct system complexity increases
2Loss of information
If the mobile robot provides detailed operation recommendations, then the information completeness is improved, but the loss of time for user decision-making increases
Solution Approach 1:
The patent segments information presentation into distinct visual patterns (different colors, blinking modes, or light positions) that encode different operation recommendations, allowing users to quickly distinguish between various operational states without processing lengthy text descriptions, thus reducing decision time while maintaining information completeness
Solution Approach 2:
The light emission unit employs periodic actions such as blinking or pulsing patterns to convey different types of operation recommendations, where the rhythm and pattern of light changes provide intuitive temporal cues that help users rapidly understand the urgency and nature of recommended operations without requiring detailed analysis

AI summary
A control system is configured to execute system control of controlling a system including a mobile robot that is configured to autonomously move and on which a user operation is executed. The system includes a light emission unit. The control system includes one or more processors. The one or more processors are configured to execute the system control. The system control includes light emission control of causing the light emission unit to emit light in different light emission patterns associated with each of a plurality of predetermined conditions. At least one of the plurality of predetermined conditions is a recommendation condition that is a predetermined condition for recommending a user operation on the mobile robot or a non-recommendation condition that is a predetermined condition for not recommending a user operation on the mobile robot.
