Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot operating systems face difficulties in installing repeaters in new task execution regions, experiencing communication disconnections due to inappropriate repeater placement and the need for frequent reinstallation when the task robot's travel path changes.
Innovation Solution
Implementing a robot operating method that uses mobile relay robots to relay communication between the host device and the task robot, with the number of mobile relay robots determined by the longest distance and environmental factors, allowing for convenient installation and reinstallation as needed.

Engineering Contradiction Analysis
1Area of stationary object
If repeaters are installed to extend communication radius, then communication coverage is improved, but installation complexity and time increase
Solution Approach 1:
The mobile robot performs self-positioning and self-deployment as a repeater node. The robot autonomously navigates to optimal positions and establishes communication relays without human intervention, eliminating the need for manual repeater installation while extending communication coverage.
Solution Approach 2:
The system transitions from static repeater installation to dynamic mobile robot-based communication relay. The mobile robot can dynamically adjust its position and function as a moving repeater node, providing flexible communication coverage extension without permanent installation infrastructure.
2Reliability
If repeaters are installed in fixed positions, then communication stability is improved, but adaptability to path changes decreases
Solution Approach 1:
The mobile robot provides dynamic communication relay capability, allowing the system to adapt to changing task execution regions and robot travel paths. The mobile robot can relocate itself to maintain optimal communication positions, providing both stability through continuous connectivity and adaptability to environmental changes.
Solution Approach 2:
The mobile robot acts as a mobile intermediary communication node between the host device and the task execution environment. This intermediary can dynamically position itself to maintain communication links even when the primary robot's path changes, ensuring communication stability while adapting to new conditions.
3Area of stationary object
If manual communication tests are performed to find repeater positions, then communication coverage is optimized, but time consumption increases
Solution Approach 1:
The mobile robot autonomously performs position optimization without requiring manual communication tests. The robot uses its own sensing and navigation capabilities to determine optimal communication relay positions, eliminating the time-consuming process of repeated manual testing while achieving effective communication coverage.
Solution Approach 2:
The system replaces manual mechanical positioning and testing with automated mobile robot navigation and communication relay. The mobile robot uses automated control systems to optimize its position as a communication node, substituting the manual trial-and-error process with efficient automated positioning.
