Cooperative Robot Coordination for Abnormal Event Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems rely on single robots for monitoring and responding to abnormal events, which limits their effectiveness in large areas and can be compromised by malfunctions, leading to high false alarm rates and incomplete event detection due to insufficient mobility and intelligence.
Innovation Solution
A method for coordinating multiple cooperative robots to detect and respond to abnormal events by forming instantly designated task teams and prioritizing tasks based on event severity and robot capabilities, ensuring effective event handling and conflict avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single robot is used for security patrol, then the system complexity is reduced, but the detected range and response effectiveness to abnormal events are limited
Solution Approach 1:
The security system is segmented into multiple independent robots instead of using a single robot. Each robot can autonomously detect and respond to abnormal events, thereby expanding the overall detected range while maintaining manageable system complexity through modular design.
Solution Approach 2:
Multiple robots are merged into a cooperative system where they share information and coordinate their actions. The robots combine their detection capabilities to cover larger areas and work together to eliminate abnormal events, achieving synergistic effects that exceed the sum of individual capabilities.
2Device complexity
If a single robot responds to abnormal events, then the device complexity is low, but the response time and effectiveness are insufficient when multiple sensors detect events simultaneously
Solution Approach 1:
The response task is segmented among multiple robots based on their locations and capabilities. When multiple sensors detect abnormal events, different robots can simultaneously respond to different events, reducing the overall response time and avoiding the bottleneck of a single robot having to travel to each location sequentially.
Solution Approach 2:
Multiple robots serve as copies of the same functional unit, each capable of independently detecting and responding to abnormal events. This redundancy ensures that response capabilities are distributed across the system, allowing parallel responses to multiple events and reducing response time.
3Adaptability or versatility
If task handover between robots is implemented, then the versatility of the system is improved, but the ability to effectively eliminate abnormal events is reduced since only one robot executes the task
Solution Approach 1:
Instead of handover where only one robot executes the task, the system merges multiple robots into a task team that executes the elimination task together. This collaborative approach maintains the adaptability of task assignment while significantly improving reliability by having multiple robots work together to eliminate abnormal events such as fires.

AI summary
A method for coordinating cooperative robots is provided. The method includes following steps. An abnormal event is detected by a sensor disposed in an environment or in a robot. The abnormal event is broadcasted to the cooperative robots. Each robot determines whether the priority of the abnormal event is higher than that of its currently executing task. If the answer is “yes,” whether function attributes of the robot meet attributes of the abnormal event is then determined. If the function attributes of the cooperative robot do not meet the attributes of the abnormal event, the robot broadcasts to acquire help from other robots, thereby constituting an instantly designated task team. The instantly designated task team goes to where the abnormal event takes place to process the abnormal event. After the abnormal event has been eliminated, the instantly designated task team is dismissed and these robots resume their original tasks.
