Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot control methods do not effectively address cooperative work scenarios where robots need to perform tasks in a common workspace with other robots or workers, lacking synchronization and coordination mechanisms.
Innovation Solution
A control device and method that generates operation sequences based on prediction results from other working bodies, synchronizing robot operations with those of other entities through an operation sequence generation unit and synchronization management unit to ensure coordinated task execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a robot performs tasks in a common workspace with other robots or workers without synchronization mechanisms, then the robot can operate independently, but coordination and collaboration efficiency deteriorate
Solution Approach 1:
The patent introduces a synchronization mechanism that acts as an intermediary between the robot and other working bodies. This mechanism manages operation sequences and coordinates timing without requiring complex direct communication between all entities, thereby improving coordination efficiency while controlling system complexity through a centralized coordination approach
Solution Approach 2:
The synchronization mechanism dynamically adjusts operation sequences based on real-time predictions of other working bodies' actions. The system adapts the robot's operation timing and sequence dynamically rather than using fixed predetermined sequences, enabling flexible coordination in changing work environments
2Manufacturing precision
If the robot executes predetermined operation sequences without considering other working bodies, then the control process is simple, but task execution accuracy and timeliness worsen
Solution Approach 1:
The system performs preliminary prediction of other working bodies' operations before generating the robot's operation sequence. By anticipating future actions of other entities in advance, the synchronization mechanism can plan coordinated sequences that ensure accurate and timely task execution without requiring complex real-time reaction mechanisms
Solution Approach 2:
The operation sequence generation incorporates feedback from predictions about other working bodies' actions. The system continuously monitors and adjusts operation sequences based on predicted states and actions of other entities, ensuring that the robot's actions remain synchronized and accurate in dynamic cooperative scenarios
3Productivity
If the robot operates without synchronization with other working bodies, then the system is simple to implement, but cooperative work effectiveness deteriorates
Solution Approach 1:
The synchronization mechanism serves as an intermediary layer that manages coordination between the robot and other working bodies. It handles the complexity of cooperative work management centrally, allowing individual components to remain relatively simple while achieving effective collaboration through the mediating synchronization layer
Solution Approach 2:
The system uses prediction models that create virtual representations or copies of other working bodies' anticipated actions. By working with these predictive models rather than direct real-time interactions, the synchronization mechanism can coordinate effectively while managing complexity through simulated rather than direct coordination channels

AI summary
A control device 1C mainly includes an operation sequence generation means 16C and a synchronization management means 17C. The operation sequence generation means 16C is configured to generate, based on an operation prediction result R2a of another working body which performs cooperative work with a robot which executes a task, an operation sequence Sra to be executed by the robot. The synchronization management means 17C is configured to synchronize an operation executed by the robot during execution of the operation sequence Sra and an operation executed by the other working body.
