Mobile Robot Control System for Dynamic Safety Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot control systems fail to ensure consistent safety for the surroundings of mobile robots, as safety depends on the operator, leading to variability in safety measures.
Innovation Solution
A control system that uses processors to recognize features around an operation interface and adjust operation limitations based on predetermined conditions, such as the presence of non-staff members or children, to maintain consistent safety by imposing or relaxing limitations and potentially stopping the robot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operation interface is made accessible to all users, then ease of operation is improved, but safety reliability deteriorates due to variability in operator competence
Solution Approach 1:
The operation limitation is made dynamic by automatically adjusting it based on the recognized feature of the mobile body. The control unit changes the operation limitation according to whether the mobile body is identified as a staff member or non-staff member, allowing the system to adapt safety levels in real-time rather than using fixed limitations
Solution Approach 2:
The system changes the parameter of operation limitation based on the recognized feature of the mobile body. When a non-staff member or child is detected, the operation limitation is imposed or increased; when a staff member is detected, the limitation is relaxed or removed, thereby maintaining safety while allowing flexible operation
2Reliability
If operation limitation is imposed to ensure safety, then safety reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The operation limitation is dynamically adjusted based on the recognized feature of the mobile body. The system automatically relaxes limitations when staff members are present and imposes them when non-staff members or children are detected, optimizing both safety and operational convenience in different contexts
Solution Approach 2:
The system performs automatic recognition and judgment of the mobile body's feature without requiring manual input from the operator. The control unit autonomously determines whether to impose operation limitation based on the recognized feature, eliminating the need for operators to manually adjust safety settings

AI summary
A control system includes one or more processors configured to perform system control for controlling a system including a mobile robot configured to move autonomously and to be operated by a user based on a feature of a mobile body present around an operation interface configured to operate the mobile robot. The system control includes change control for changing operation limitation on the operation interface when the feature satisfies a predetermined condition.
