Robot Teaching Visualization of Position and Attitude States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot teaching systems fail to effectively display the position and attitude of a robot operating according to a working program, making it difficult for operators to easily confirm these parameters, especially in simulator environments.
Innovation Solution
A robot teaching system that includes a robot position and attitude calculation unit, an imaginary robot information generation unit, a teaching instruction selection unit, and a display unit, which calculates and displays the positions and attitudes of a robot corresponding to teaching instructions and points between them, allowing for easy confirmation through various display modes such as still images or animations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pseudo robot is operated in a simulator environment, then the robot operation can be simulated without operating the actual robot, but it is not possible to easily ascertain the positions and attitudes of the robot corresponding to respective teaching instructions
Solution Approach 1:
The patent creates a virtual robot that replicates the appearance and movement of the actual robot in the simulator environment. This virtual copy displays the robot's position and attitude information, allowing operators to easily ascertain robot states without directly observing the actual robot or dealing with complex coordinate data.
Solution Approach 2:
The patent introduces a virtual robot as an intermediary between the actual robot and the operator. This intermediary visually represents the robot's position and attitude in an easily understandable format, bridging the gap between the simulator environment and the operator's need for clear position information.
2Loss of information
If the operation track of the robot is displayed, then the robot's movement path can be visualized, but the position and attitude of the robot at specific teaching instructions are not displayed
Solution Approach 1:
Instead of modifying the existing display system to show additional position and attitude data, the patent creates a visual copy of the robot that inherently displays its position and attitude through its rendered appearance in the simulator environment.
Solution Approach 2:
The patent replaces complex data representation methods with a visual rendering approach. Instead of using technical displays showing numerical position and attitude data, the system uses graphical rendering of the virtual robot to convey this information intuitively.

AI summary
A robot teaching system includes: a robot position and attitude calculation unit that calculates positions and attitudes of a robot corresponding to respective teaching instructions and points between the respective teaching instructions included in a working program for operating the robot; an imaginary robot information generation unit that generates imaginary robot information corresponding to the respective teaching instructions and the points between the respective teaching instructions on a basis of the positions and attitudes of the robot; a teaching instruction selection unit that selects at least one of the respective teaching instructions included in the working program; and a display unit that displays the imaginary robot information on a basis of the selected teaching instruction. The robot teaching system is able to easily confirm the position and attitude of the robot in an arbitrary teaching instruction of the working program.
