Robot Video Confirmation Using Synchronized Model and Camera Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robots in wafer processing facilities often generate errors, necessitating quick identification and resolution, but data transfer and communication restrictions hinder effective troubleshooting.
Innovation Solution
A video confirmation computer that displays a side-by-side model and video of the robot's operation, synchronized with a communication log, enabling intuitive understanding of the robot's posture and errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transfer and communication with external networks are restricted to maintain information management security, then system security is improved, but the ability to quickly identify and resolve robot errors deteriorates
Solution Approach 1:
The system creates a virtual copy of the robot's operational environment by generating a two-dimensional or three-dimensional model that reproduces the robot's posture and movements. This model is displayed alongside actual camera footage, allowing operators to analyze robot operations and identify errors without requiring external network communication or data transfer, thus maintaining security while enabling effective troubleshooting.
2Device complexity
If traditional separate display methods are used for robot operational data and video footage, then system complexity is reduced, but the operator's understanding of robot situation deteriorates
Solution Approach 1:
The system merges the display of robot operational data (two-dimensional or three-dimensional models showing robot posture) with actual video footage from cameras attached to the robot. Both the model area and video area are displayed side by side on the same screen, allowing operators to simultaneously view both the reconstructed robot model and actual camera footage, thereby achieving comprehensive understanding without significantly increasing system complexity.
Data Source
AI summary
A video confirmation computer for confirming video related to robot operation includes a storage unit and a processor. The storage unit stores information on the position of the electric motor that drives a link body of the robot received from the controller of the robot and information on the video obtained by a camera attached to the robot. The processor makes at least one of the video confirmation computer itself and a computer connected to the video confirmation computer display a model area and a video area side by side. In the model area, a two-dimensional or three-dimensional model reproducing the posture of the robot is displayed by computer graphics. In the video area, the video is displayed.
