Warehouse Robot Queue Control for Collision-Free Workflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Warehouse Management Systems (WMS) require significant time, labor, and energy due to inefficient management of warehouse operations without optimal consideration of geospatial factors and lack of regulated autonomous elements, leading to issues like collisions and traffic jams among robots.
Innovation Solution
A system and method for queueing robots in a warehouse environment based on workflow optimization instructions, using central processors to direct robots to adjacent queuing positions and prevent collisions, optimizing time, labor, and energy requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If robots are employed for warehouse operations without optimal direction considering geospatial factors, then automation is achieved, but collisions and traffic jams occur
Solution Approach 1:
The system performs preliminary actions by establishing queue positions for robots before they arrive at potential collision zones. The control system calculates and assigns specific queue positions to robots based on their current locations and destinations, preventing collisions before they can occur. This proactive queue management ensures robots maintain safe distances and coordinated movement patterns throughout warehouse operations.
2Productivity
If robots operate without centralized queue management, then operational flexibility is maintained, but traffic jams and obstructions form
Solution Approach 1:
The queue management system dynamically adjusts robot queue positions and movement instructions in real-time based on changing warehouse conditions. As robots complete tasks, move to new destinations, or encounter obstacles, the control system recalculates optimal queue positions and provides updated navigation instructions. This dynamic approach maintains continuous workflow and prevents traffic jams while minimizing robot waiting time.
3Device complexity
If traditional WMS processes are used without geospatial optimization, then simplicity is maintained, but time and energy consumption increase
Solution Approach 1:
The system applies local quality optimization by considering the specific geospatial characteristics of different warehouse locations when directing robot movements. The control system analyzes the warehouse layout, identifying optimal pathways, queue positions, and traffic flow patterns based on local conditions such as aisle widths, storage rack configurations, and high-traffic areas. This localized optimization reduces unnecessary robot travel distances and energy consumption while maintaining operational efficiency.

AI summary
A system and method are described that provide for queueing robot operations in a warehouse environment based on workflow optimization instructions. In one example of the system/method of the present invention, a control system causes certain robots to queue proximate to one another to permit resources to be obtained, transported, deposited, etc. without the robots crashing into one another (or into other objects), or forming traffic jams. A robot may remain at an assigned queue position at least until another position assigned to the robot becomes available.
