Mobile Robot Recovery Priority Control in Facility Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot control systems do not effectively prioritize recovery operations for mobile robots in a recovery requiring state, leading to potential delays in urgent recovery situations.
Innovation Solution
A robot control system that detects mobile robots in a recovery requiring state and notifies relevant personnel of their recovery priorities, allowing for preferential start of recovery operations on robots with the highest priority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile robots are managed without recovery priority determination, then the system is simpler to operate, but recovery of urgent robots is delayed
Solution Approach 1:
The control device determines recovery priorities in advance before actual recovery operations are needed. By pre-establishing priority levels based on robot function, position, and task importance, the system prepares recovery sequences ahead of time, ensuring urgent robots are recovered first without delaying response time
Solution Approach 2:
The control device continuously monitors robot operational states and dynamically adjusts recovery priorities based on real-time information. When a robot enters a recovery requiring state, the system evaluates current conditions and provides feedback on priority levels, allowing operators to make informed decisions about recovery sequencing
2Productivity
If recovery priorities are determined and notified for multiple robots, then recovery efficiency is improved, but the control system becomes more complex
Solution Approach 1:
The control device segments the fleet of mobile robots into distinct priority groups based on recovery urgency. By dividing robots into priority levels (e.g., high, medium, low), the system manages complexity through categorization, allowing operators to focus on high-priority robots first while systematically addressing lower-priority ones
Solution Approach 2:
The control device uses multiple parameters (robot function, current position, task importance) to determine and adjust recovery priorities. By changing priority parameters dynamically based on these factors, the system optimizes recovery efficiency without requiring overly complex control mechanisms
3Reliability
If all mobile robots are recovered simultaneously, then overall system availability is improved, but urgent recovery tasks are delayed
Solution Approach 1:
The control device pre-determines recovery sequences by evaluating robot priorities before recovery operations begin. By establishing a prioritized recovery schedule in advance, the system ensures urgent robots are addressed first while planning for subsequent recovery of less critical robots, balancing immediate needs with overall availability
Solution Approach 2:
The control device dynamically adjusts recovery priorities based on changing operational conditions. As robots are recovered and operational states change, the system re-evaluates priorities to maintain optimal recovery sequencing, ensuring urgent tasks remain prioritized while working toward comprehensive system availability

AI summary
A robot control system according to the present embodiment includes a plurality of mobile robots that moves autonomously in a facility and a control device that controls the mobile robots. When the control device detects that two or more of the mobile robots are in a recovery requiring state, the control device notifies that the two or more mobile robots are in the recovery requiring state, together with priorities of the two or more mobile robots.
