1Quantity of substance
If multiple working robots share a common charging base, then facility cost is reduced, but waiting time increases due to resource contention
Solution Approach 1:
The motion control part calculates and determines charging schedules in advance before the robots actually need to charge. By predicting robot positions, work completion times, and battery states, the system pre-arranges charging time slots for each robot, allowing them to charge sequentially without idle waiting. This transforms reactive resource contention into proactive resource allocation.
Solution Approach 2:
The charging schedule is not fixed but dynamically adjusted based on real-time robot positions, work progress, and battery states. The motion control part continuously monitors robot status and recalculates charging schedules to optimize the use of the single charging base, adapting to changing conditions rather than following a rigid timetable.
2Ease of operation
If multiple working robots operate autonomously without coordination, then operational flexibility is improved, but collision risk and work interference increase
Solution Approach 1:
The motion information sharing part creates a communication feedback loop where all robots continuously share their positions, speeds, and work status with each other and with the management device. This real-time information exchange allows each robot to adjust its autonomous operations based on the current state of the field and other robots, maintaining operational flexibility while preventing collisions and work interference through coordinated awareness.
Solution Approach 2:
The central management device acts as an intermediary that receives motion information from all robots, processes this data to determine optimal motion control for each robot, and then issues coordinated commands. This intermediary layer enables autonomous robots to work together harmoniously by mediating their interactions and resolving potential conflicts before they occur.

AI summary
The present invention makes it possible, when a plurality of work robots perform work on one field, for each of the plurality of work robots to perform the individual work smoothly and efficiently. This work robot management system is for managing motions of each of a plurality of work robots that perform work on one field while autonomously traveling. This work robot management system comprises: a motion information sharing unit that shares information concerning the motions of each of the work robots; and a motion control unit that controls the motions of each of the work robots on the basis of the information shared by the motion information sharing unit. On the basis of information concerning at least one of the motions of each of the work robots, motions of the other work robots that perform work, different from the at least one of the motions of each of the work robots, are controlled.
