Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot performs automatic work using stored operational information, then productivity is improved, but adaptability deteriorates when work targets or environments change
Solution Approach 1:
The system introduces feedback by detecting actual robot operations and environmental information during automatic work, comparing them with stored operational information, and automatically correcting deviations. This feedback loop enables the robot to adapt to changes in work targets or environments while maintaining automatic operation efficiency.
2Manufacturing precision
If teaching information is corrected manually through direct teaching or programming, then accuracy is improved, but loss of time increases due to repeated corrections
Solution Approach 1:
The system enables self-service by allowing the robot to automatically detect operational deviations and environmental changes during automatic work, and autonomously correct its operational information without requiring manual intervention. This self-correction capability maintains high accuracy while eliminating time-consuming manual re-teaching.
3Reliability
If the robot operates strictly according to taught information, then reliability is improved for consistent reproduction, but adaptability worsens when defects are discovered
Solution Approach 1:
The system applies dynamics by making the operational information flexible and updateable during execution. While the robot maintains consistent reproduction of taught operations for reliability, the system dynamically allows real-time detection and correction of operational information when defects are discovered or environmental changes occur, balancing consistency with adaptability.

AI summary
A robot control device includes a memory part configured to store storing operational information for causing the robot to perform a given operation, and a processing part configured to control operation of the robot by using the storing operational information as automatic operational information for causing the robot to perform an automatic work. The processing part is adapted to accept manipulational information for correcting the operation of the robot performing the automatic work using the automatic operational information, from a manipulating device, control the robot to perform operation corrected from the operation related to the automatic operational information, and store in the memory part corrected operational information for causing the robot to perform the corrected operation as the storing operational information. The manipulating device outputs to the processing part the manipulational information based on first operational information indicative of the operation of the manipulating device.
