3D Robot Simulation for Intuitive Off-Line Programming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-line programming for robots typically limits operators to a two-dimensional view, making it difficult to intuitively grasp the state of the robot system, which can lead to a lack of perspective and accuracy in creating operation programs.
Innovation Solution
A robot simulation device that displays a three-dimensional model of the robot system, including a robot, workpiece, and peripheral devices, using augmented reality to superimpose these models onto a real-space image, allowing operators to intuitively understand the system's state and create accurate operation programs through a head-mounted display or projector.

Engineering Contradiction Analysis
1Device complexity
If a two-dimensional screen is used to display the robot system model, then the device complexity is reduced, but the operator's ability to intuitively grasp the system state deteriorates
Solution Approach 1:
The patent transitions from a two-dimensional screen display to a three-dimensional holographic display, allowing the robot system model to be visualized in spatial depth. This dimensional change enables operators to view the robot, workpiece, and peripheral devices from multiple angles and perspectives, significantly improving intuitive understanding while maintaining manageable device complexity through software-based holographic rendering.
2Device complexity
If a two-dimensional screen is used for simulation display, then the device complexity is reduced, but the manufacturing precision of operation programs deteriorates
Solution Approach 1:
By implementing a three-dimensional holographic display, the system allows operators to accurately assess spatial relationships, robot positions, and workpiece interactions in a virtual environment that mirrors real-world geometry. This enhanced visualization precision enables more accurate programming of robot movements and operations, reducing errors in the generated operation programs.
3Ease of operation
If a three-dimensional holographic display is used, then the operator's intuitive understanding is improved, but the device complexity increases
Solution Approach 1:
The system creates a virtual holographic copy of the robot system, including the robot, workpiece, and peripheral devices, which can be displayed and manipulated without requiring physical three-dimensional hardware. This virtual copying approach achieves intuitive three-dimensional visualization while avoiding the complexity of specialized display hardware, as the holographic rendering is performed through software on standard computing devices.
4Manufacturing precision
If a three-dimensional holographic display is used, then the manufacturing precision of operation programs is improved, but the device complexity increases
Solution Approach 1:
The virtual holographic copy provides accurate spatial representation of the robot system, enabling precise programming of operation paths and positions. The software-based holographic rendering maintains high measurement precision for program creation while avoiding the need for complex specialized display hardware, thus achieving accurate operation programs without proportionally increasing device complexity.
