Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient methods for unmanned ground robots to determine and prevent obstruction of pedestrian traffic, particularly in environments with complex pedestrian dynamics and limited communication infrastructure.
Innovation Solution
The proposed solution involves a method and system where unmanned ground robots, equipped with transceivers, processors, and memory, determine if they obstruct pedestrian traffic and decide on operations to prevent obstruction, such as group driving with other robots, modifying their driving paths, or pausing their operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If unmanned ground robots operate independently without coordination, then device complexity is reduced, but pedestrian traffic obstruction increases
Solution Approach 1:
The patent merges multiple unmanned ground robots into a coordinated group that operates collectively. The robots share positional information and coordinate their movements through wireless communication, transforming individual independent operations into a unified group behavior that reduces pedestrian obstruction while maintaining manageable system complexity through modular architecture.
2Reliability
If unmanned ground robots perform real-time pedestrian detection and path adjustment, then pedestrian safety is improved, but processing time and computational load increase
Solution Approach 1:
The patent implements preliminary action by having robots continuously share positional information and predict potential obstruction scenarios before they occur. The system pre-calculates safe paths and coordinates movements in advance, allowing robots to respond to pedestrian presence more quickly and safely without excessive processing delays during critical moments.
Solution Approach 2:
The patent employs feedback mechanisms where robots continuously monitor pedestrian positions, detect potential obstructions, and adjust their paths in real-time based on sensor data and communication with other robots. This closed-loop control system improves pedestrian safety by enabling dynamic response to changing conditions while optimizing processing efficiency through selective attention to critical threats.
3Productivity
If multiple robots operate in the same area without coordination, then productivity is maintained, but traffic obstruction and safety risks increase
Solution Approach 1:
The patent applies dynamics by enabling robots to flexibly adjust their operational patterns based on real-time conditions. When pedestrian presence is detected, robots dynamically modify their paths, speeds, and coordination strategies while maintaining overall mission objectives. This dynamic adaptation allows the system to preserve productivity during low-traffic periods while automatically reducing obstruction risks during high-traffic periods through coordinated behavior changes.
