Mobile Robot Motion Mode Permission Control for Safe Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile robot control systems lack a mechanism to ensure safe motion mode changes by directly verifying permission before executing requests, potentially leading to unsafe operations.
Innovation Solution
A method and apparatus for controlling mobile robots that involve receiving a motion mode change request, determining if the robot has permission to move based on predefined models or information, and sending confirmation to change the motion mode only if permission is granted, using over-the-air technology for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If motion mode change requests are executed directly without permission verification, then the robot responds quickly to commands, but unsafe operations may occur
Solution Approach 1:
The system performs preliminary permission verification before executing motion mode changes. The server checks whether the robot is authorized to transition to the requested motion mode using a permission model that evaluates robot identification, current state, and environment information. This advance verification ensures safety while maintaining responsive operation.
2Reliability
If permission verification mechanisms are implemented, then operation safety is improved, but system complexity increases
Solution Approach 1:
The system introduces a server as an intermediary between the robot and motion mode change requests. The server hosts the permission model and handles verification logic centrally, preventing the robot itself from becoming complex. This distributed architecture separates safety-critical verification from execution, simplifying the robot's control system while ensuring reliable operation.
3Reliability
If real-time monitoring and verification are performed, then motion safety is enhanced, but communication overhead increases
Solution Approach 1:
The system performs partial verification by selectively evaluating only the necessary parameters for permission determination. The permission model checks robot identification, current motion mode, and environment information only when motion mode changes are requested, rather than continuously monitoring all parameters. This reduces communication overhead while maintaining safety for critical transitions.

AI summary
A method, an apparatus and a control system for controlling a mobile robot are provided. The method includes: receiving a motion mode change request sent by a target mobile robot, the motion mode change request including motion mode information, and the motion mode information being information of a motion mode to be obtained by change requested by the target mobile robot; determining whether the target mobile robot has a permission to move in the motion mode; and sending motion confirmation information for the motion mode change request to the target mobile robot to control the target mobile robot to move in the motion mode, in response to determining that the target mobile robot has the permission.
