Robot Path Error Visualization for Industrial Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial robots often experience process errors during workpiece processing, such as insufficient paint flow, which are difficult to diagnose due to their occurrence along a preprogrammed path, making it hard to identify the cause visually.
Innovation Solution
A method and system that store information about error locations along the robot path and generate a visualization of the robot path and errors in relation to the workpiece, allowing users to reprogram the path and identify fault causes, including three-dimensional visualizations to enhance diagnosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If error log list is presented as printed list or on display connected to process controller, then error information is provided to user, but user cannot easily identify the location and cause of errors along robot path
Solution Approach 1:
The patent transforms error location data from a one-dimensional list format into a two-dimensional visual representation by overlaying error markers on a graphical display of the robot path. This allows users to see the spatial distribution of errors along the path, making it immediately apparent where errors occur without having to search through text logs or correlate timestamps with physical locations.
2Extent of automation
If robot path is preprogrammed and errors occur during processing, then processing automation is achieved, but errors repeatedly occur at same position making cause hard to find
Solution Approach 1:
The system provides visual feedback by displaying error locations overlaid on the robot path graphic. When errors occur during automated processing, their positions are marked on the path display, giving immediate feedback about where problems occur. This enables operators to quickly identify patterns, such as errors consistently occurring at specific locations, and determine whether the issue is related to tool position, workpiece features, or path programming.
Data Source
AI summary
A system for visualizing process errors that occur in connection with processing a workpiece by means of a process tool and an industrial robot moving the tool along a path in relation to the workpiece during the processing. The system is configured to store information on process errors and information on where on the robot path the error occurred upon detecting the process errors and to present a visualization of the robot path and the position of the stored errors in relation to the robot path.
