Robot Sensor Abnormality Return Control for Faster Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In robot systems, detecting and addressing abnormalities in the operation of conveying devices and robots is time-consuming, prolonging the boot-up time due to the difficulty in identifying and correcting issues without manual intervention.
Innovation Solution
A robot system with an integrated abnormality detection processing unit that automatically returns the robot to the position of the detected abnormality and stops, allowing operators to perform adjustments efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot system operates at high speed with repeated image capture and detection processing, then productivity is improved, but it becomes difficult for operators to check processing at each position, leading to increased teaching and adjustment time when abnormalities occur
Solution Approach 1:
The robot controller automatically returns the robot to the position where the abnormality occurred before operator intervention is needed. This preliminary action of automatic return eliminates the time-consuming manual movement of the robot to the problem spot, directly reducing teaching and adjustment time while maintaining high-speed operation capabilities
2Productivity
If the robot system operates continuously at high speed, then productivity is improved, but the boot-up time is lengthened when abnormalities need to be addressed
Solution Approach 1:
The robot system performs self-service by automatically returning to the abnormality position without requiring operator intervention for position recovery. This self-service capability reduces the boot-up time when abnormalities occur, as the system can quickly reset itself while maintaining continuous high-speed operation during normal production
3Measurement precision
If manual checking and adjustment of each position is performed, then operational accuracy is maintained, but the complexity of operation increases and time is lost
Solution Approach 1:
The system uses feedback from the sensor to automatically determine when an abnormality has occurred and to control the robot's return to the specific position where the abnormality was detected. This feedback mechanism maintains detection accuracy while eliminating the need for manual checking of each position, thereby reducing operational complexity and time
