Robot Teaching and Manual Correction During Automatic Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot teaching methods require significant operator effort and time, especially when changes are needed in the work target or environment, leading to potential operational failures and reduced accuracy, and correcting robot operations is burdensome using traditional remote control teaching pendants.
Innovation Solution
A robot system comprising a robot main body with multiple joints, a control device, and an operating device that includes a teaching device for positional and angular information input and a manipulator for manual operation correction, allowing for reduced operator workload and easy correction of preset operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If teaching is performed by remote control using a teaching pendant, then the robot can be taught positional information and angular information, but the operator's workload increases and the teaching process becomes time-consuming
Solution Approach 1:
The patent replaces the mechanical teaching pendant operation with an optical/image processing system. The imaging device captures images of the workpiece, and image processing automatically extracts position coordinates, substituting the manual mechanical input method with an automated visual recognition system.
Solution Approach 2:
The system enables self-service teaching by allowing the robot to automatically acquire position information through image processing. The workpiece itself provides the teaching information through its visual features, eliminating the need for operator intervention in coordinate input.
2Measurement precision
If teaching is performed by remote control using a teaching pendant, then the robot can be taught positional information and angular information, but the complexity of the teaching operation increases
Solution Approach 1:
The patent replaces the mechanical teaching pendant operation with an optical/image processing system. The imaging device captures images of the workpiece, and image processing automatically extracts position coordinates, substituting the manual mechanical input method with an automated visual recognition system.
Solution Approach 2:
The system creates a visual copy (image) of the workpiece and extracts teaching information from this copy rather than requiring direct manual measurement and input. This copying approach simplifies the teaching operation by working with image data instead of physical measurements.
3Adaptability or versatility
If the robot operation needs to be corrected after teaching, then the teaching information can be changed, but the correction process requires significant time and labor
Solution Approach 1:
The system creates a visual copy (image) of the workpiece and extracts teaching information from this copy rather than requiring direct manual measurement and input. This copying approach simplifies the teaching operation by working with image data instead of physical measurements.
Solution Approach 2:
The system allows dynamic adjustment of teaching information by enabling operators to modify position coordinates based on image data or recapture images for correction, making the correction process flexible and adaptable rather than requiring complete re-teaching.
4Adaptability or versatility
