Robot Controller Autonomous Positioning with Human Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The aging workforce and shortage of skilled operators in robotics have led to a concern for the manual operation of robots, which requires expert judgment, limiting the diversification of available operators.
Innovation Solution
A controller system that enables robots to autonomously perform tasks by acquiring state information, determining work positions, and transmitting selection requests to an operation terminal, allowing the robot to operate autonomously based on user-selected positions via a communication network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control is used for robot operations requiring judgment, then operation quality is maintained, but operator shortage and aging limit availability
Solution Approach 1:
The patent segments the robot operation into two parts: autonomous positioning operations performed by the robot itself, and judgment-based selection operations performed by the human operator. This segmentation allows the system to leverage both automated efficiency and human judgment capability, resolving the contradiction between operator availability and automation capability.
Solution Approach 2:
The robot performs self-positioning and self-operation based on position information received from the operator, without requiring continuous manual control. This self-service approach enables the robot to autonomously execute tasks while the operator only needs to provide high-level guidance, thereby increasing operator availability while maintaining automation.
2Extent of automation
If autonomous control is implemented, then operator diversification is enabled, but judgment-based operations require human intervention
Solution Approach 1:
The patent introduces a communication terminal as an intermediary between the operator and the robot. The terminal receives position information from the operator, transmits it to the robot, and receives operation results back. This intermediary simplifies the control interface while enabling autonomous operation, resolving the contradiction between automation capability and control system complexity.
3Measurement precision
If full manual control is used, then judgment accuracy is maintained, but operation time increases
Solution Approach 1:
The patent applies partial automation where the robot autonomously performs the time-consuming positioning and execution operations, while the operator performs only the critical judgment-based selection of position information. This partial action approach maintains judgment accuracy while significantly reducing operation time.

AI summary
A controller that performs a control in which a robot autonomously performs a given work includes a first processor. The first processor performs processing including acquiring state information including a state of a workpiece that is a work target while performing the given work, determining candidates of a work position of the workpiece based on the state information, transmitting a selection request for requesting a selection of the work position from the candidates of the work position to an operation terminal, the operation terminal being connected data-communicably with the first processor via a communication network, and when information on a selected position that is the selected work position is received from the operation terminal, causing the robot to operate autonomously according to the selected position.
