Virtual Robot Teaching for Safe Motion Observation and Point Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teaching systems for robots struggle to accurately generate teaching points due to the user's distance from the robot, making it difficult to observe the robot's motion and generate appropriate teaching points.
Innovation Solution
A teaching system that includes a teaching point generator, an operator, an image generator, and a display, which creates a virtual image of a robot in a virtual space, allowing the user to operate the virtual robot and generate teaching points based on its position in the virtual space.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the user is located away from the robot, then the safety of the user is improved, but the ability to observe the robot's motion is worsened
Solution Approach 1:
The patent creates a virtual robot that is a digital copy of the physical robot, allowing the user to observe and interact with the copy from a safe distance. The virtual robot replicates the motion and behavior of the physical robot, enabling effective observation without requiring physical proximity that would compromise safety.
Solution Approach 2:
The patent transitions the observation interface from physical space to virtual/digital space. By displaying the virtual robot on a screen or in a virtual environment, the user can observe robot motion from multiple angles and distances that are not constrained by physical space limitations, maintaining safety while improving observation capability.
2Object-affected harmful factors
If the user is located away from the robot, then the safety of the user is improved, but the accuracy of generating teaching points is worsened
Solution Approach 1:
The virtual robot serves as an accurate digital replica that preserves all motion characteristics and positional data of the physical robot. This copying enables precise teaching point generation through virtual interaction, achieving the same measurement precision as direct physical interaction would provide, while maintaining user safety at a distance.
Solution Approach 2:
The system provides real-time feedback by synchronizing the virtual robot's motion with the physical robot's motion. This feedback loop ensures that teaching points generated in the virtual environment accurately reflect the physical robot's actual position and orientation, maintaining high precision despite the user's physical distance from the robot.

AI summary
A teaching system includes a teaching point generator that generates a teaching point of a robot; an operator that is operated by a user; an image generator that generates a VR image in which a virtual robot corresponding to the robot is placed in a VR space; and a display that displays the VR image. The image generator generates the VR image in which the virtual robot moves in accordance with operation to the operator. The teaching point generator generates a teaching point corresponding to a position of the virtual robot in the VR space generated by the image generator.
