Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot control methods fail to determine suitable operation sequences when robots perform tasks in a common workspace with other robots or workers, particularly in cooperative work scenarios.
Innovation Solution
A control device and method that generate operation sequences for robots based on recognition results of types and states of objects in the workspace, including other working bodies, to ensure effective cooperative work by abstracting dynamics and optimizing task execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a robot performs tasks in a common workspace with other robots or workers, then cooperative work capability is improved, but determining suitable operation sequences becomes difficult
Solution Approach 1:
The patent segments the complex cooperative work problem into distinct components: recognizing other working bodies, determining their operation sequences, and coordinating with them. The operation sequence determination is divided into specific steps including recognizing the other working body, determining its operation sequence based on recognition results, and generating the robot's own operation sequence considering the other working body's sequence. This segmentation makes the overall complex task manageable and solvable.
2Manufacturing precision
If the robot determines operation sequences considering other working bodies, then task execution accuracy is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by having the control device recognize other working bodies and determine their operation sequences before the robot executes its own tasks. The system performs recognition and sequence determination in advance, allowing the robot to plan its operations with full knowledge of the cooperative environment beforehand. This preliminary determination of operation sequences enables accurate task execution without time loss during actual execution, as all coordination decisions are made in advance.
