Examination Robot Path Teaching From Workpiece Result Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot systems lack an efficient method to automatically generate teaching information for examination robots to inspect workpieces that have undergone various types of work, such as welding, without increasing the workload of teaching the examination robot.
Innovation Solution
A teaching apparatus and method that obtain result information from the workpiece, either from the motion path of the work robot or the three-dimensional shape of the workpiece, to generate first teaching information specifying the motion path of the examination robot, allowing for automatic generation of examination-use paths that ensure the workpiece is within the examinable range of the examination device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If teaching information is manually programmed for the examination robot, then the examination robot can accurately inspect workpieces, but the teaching workload and time consumption increase significantly
Solution Approach 1:
The patent copies the motion path information from the work robot to generate examination robot teaching information. The teaching information generation unit creates examination-use motion paths by processing work-use motion path information, eliminating the need for manual programming while preserving examination accuracy through systematic transformation of the copied data.
2Productivity
If the examination robot uses a fixed motion path, then the teaching process is simplified, but the examination efficiency and coverage of work regions decrease
Solution Approach 1:
The patent segments the examination motion path into multiple examination-use motion paths corresponding to different work regions. The teaching information generation unit divides the overall examination task into region-specific paths, allowing the examination robot to efficiently cover all work areas while maintaining manageable complexity through systematic segmentation.
Solution Approach 2:
The patent implements dynamic motion paths that adapt to different work regions. The examination-use motion paths are generated to dynamically adjust the examination robot's trajectory based on the specific characteristics and positions of different work regions, optimizing examination efficiency without requiring overly complex fixed paths.
3Adaptability or versatility
If multiple examination devices are used to cover all work regions, then examination coverage is improved, but the system complexity and cost increase
Solution Approach 1:
The patent makes the examination robot multi-functional by enabling it to inspect multiple different work regions through generated motion paths. The single examination robot is equipped with the capability to perform examination tasks across various regions by processing motion path information, eliminating the need for multiple specialized examination devices while maintaining comprehensive coverage.
Data Source
AI summary
A teaching apparatus includes circuitry. The circuitry is configured to obtain result information corresponding to a position of a worked region on a workpiece. The circuitry is configured to generate first teaching information based on the result information. The first teaching information specifies a motion of an examination robot configured to examine the workpiece that has undergone work.
