Robot Control Mode Switching for Safe Anomaly Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting security anomalies in robots operating in public places fail to determine an appropriate response, potentially causing more damage by simply stopping the robot when an attack is detected, as the control state at the time of detection may not be safe.
Innovation Solution
A control mode switching apparatus and method that analyze communication messages to detect anomalies such as user, robot, and environment issues, calculating a score for each type of anomaly to switch the robot to a safer control mode based on these scores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot stops immediately when an anomaly is detected, then the security risk is reduced, but the robot may cause more damage due to abrupt stopping in certain control states
Solution Approach 1:
The patent implements dynamic control mode switching based on real-time anomaly detection results. Instead of a fixed stop response, the system dynamically adjusts the robot's control state by selecting from multiple control modes (autonomous, remote, manual) according to the detected anomaly type and severity, thereby adaptively balancing security requirements with operational safety
Solution Approach 2:
The system changes the control mode parameter in response to detected anomalies. By monitoring anomaly detection results and switching between different control modes (autonomous control, remote control, manual control), the system modifies its operational parameters to appropriate responses rather than always stopping, thus preventing unnecessary damage while maintaining security
2Productivity
If the robot continues operating in the current control mode when an anomaly is detected, then operational continuity is maintained, but security risks increase
Solution Approach 1:
The patent establishes a feedback mechanism where anomaly detection results are continuously monitored and fed back to the control mode switching apparatus. This feedback loop enables the system to adjust control modes based on real-time security状况, maintaining operational continuity when safe while switching modes when security risks are detected
Solution Approach 2:
The control mode is dynamically adjusted based on anomaly detection feedback. The system transitions between autonomous, remote, and manual control modes according to the detected anomaly type and severity, enabling flexible response that maintains productivity when safe while ensuring security when needed
3Adaptability or versatility
If multiple control modes are implemented for anomaly response, then appropriate response can be selected, but system complexity increases
Solution Approach 1:
The patent segments the anomaly response into distinct control modes (autonomous control mode, remote control mode, manual control mode). Each mode represents a segmented response strategy for different anomaly scenarios, making the complex decision-making process more manageable and systematic
Solution Approach 2:
The control mode switching apparatus serves multiple functions: it detects anomalies, evaluates security risks, determines appropriate responses, and switches between different control modes. This multi-functional design consolidates what could be separate complex systems into a single integrated apparatus, managing overall system complexity

AI summary
A control mode switching apparatus switches a control mode of a robot. The control mode includes at least two of a remote control mode, a manual control mode, and an autonomous control mode. The control mode switching apparatus includes: an anomaly detector that, based on a communication message on a control network in the robot and the control mode, obtains a detection result of at least one anomaly among a user anomaly caused by user control, a robot anomaly caused by the control network, an operating environment anomaly caused by an operating environment of the robot, and an application anomaly caused by an application; and a switcher that calculates, for each type of anomaly detected, a score indicating a likelihood that the type is a cause of the anomaly in the robot, and switches the control mode based on the score calculated.
