Laser-Guided Robot Path Control for High-Speed Obstacle Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot navigation systems require significant computing power for path generation and obstacle avoidance, limiting travel speed due to the need for continuous sensor data processing and recalculating routes in real-time.
Innovation Solution
A main server controls laser irradiation to guide a robot along a pre-calculated path, using a camera module to identify the robot's location and transmit the path to a laser irradiation module, allowing the robot to move at high speed without sensing external obstacles or recalculating routes in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot uses built-in sensors to sense obstacles and calculate paths in real-time, then the robot can autonomously navigate, but the computational burden increases and travel speed decreases
Solution Approach 1:
The patent extracts the path calculation function from the robot and relocates it to an external server. The robot only needs to execute pre-calculated paths, removing the need for complex onboard computing resources while maintaining navigation capability. This resolves the contradiction by reducing computational burden on the robot without sacrificing productivity.
Solution Approach 2:
The patent implements preliminary path calculation by the external server before the robot executes the path. The server calculates the optimal path in advance based on map data and robot location, so the robot does not need to perform real-time calculations during movement. This preliminary action enables high-speed travel without computational delays.
2Adaptability or versatility
If the robot recalculates routes in real-time to avoid obstacles, then the robot can adapt to dynamic environments, but the travel speed is limited due to continuous computation
Solution Approach 1:
The patent introduces an external server as an intermediary between the robot and the path calculation process. The server handles all path calculation and obstacle avoidance planning, receiving robot location data and returning updated paths. This intermediary approach allows the robot to maintain high speed while still adapting to dynamic environments through server-based recalculation.
3Reliability
If the robot is equipped with various sensors to sense obstacles, then the robot can navigate autonomously, but the device complexity and computing resources required increase
Solution Approach 1:
The patent extracts the complex path planning and obstacle avoidance calculation functions from the robot's onboard systems and relocates them to an external server. The robot retains only the essential sensors needed for basic localization and follows pre-calculated paths, significantly reducing device complexity while maintaining reliable autonomous navigation through server-based intelligence.
