Robot Door Traversal Control for Congestion-Free Passage Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional automation technology, congestion often occurs when multiple robots need to pass through a passage with doors, leading to low efficiency in robot access.
Innovation Solution
A robot traversal method that determines the present door corresponding to a target robot in a transition area and controls it to be opened, allowing the robot to pass through smoothly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple robots share a common passage with doors, then resource utilization is improved, but congestion occurs and access efficiency deteriorates
Solution Approach 1:
The passage is segmented into multiple transition areas by dividing it with doors. Each transition area can be independently controlled and managed, allowing robots to pass through different segments simultaneously without causing congestion. The door control device manages each segment separately, improving overall passage utilization while maintaining efficient robot access.
2Ease of operation
If doors are installed in transition areas to partition passages, then passage management is improved, but robot traversal complexity increases
Solution Approach 1:
The door control device automatically detects robot presence in transition areas using detection devices and autonomously controls door opening/closing operations. The system serves itself by making decisions based on detected robot positions and traversal needs, reducing manual intervention complexity while improving passage management efficiency.
3Reliability
If doors remain closed to maintain partitioning, then passage security is improved, but robot access speed decreases
Solution Approach 1:
The door states are made dynamic rather than static. Doors automatically transition between closed and open states based on real-time robot detection and traversal requirements. When robots are detected in transition areas, the corresponding doors open to allow passage; when no robots are present, doors remain closed to maintain partitioning. This dynamic adjustment maintains security while enabling fast robot access.

AI summary
A robot traversal method includes: when a target robot travels to a transition area, determining a present door corresponding to the target robot in the transition area; and controlling the present door to be opened and passing through the present door.
