Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If VR-based control system is implemented for industrial robots, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent creates a virtual copy (Cyber model) of the industrial robot and its workspace that mirrors the physical system in real-time. This virtual model allows operators to interact with a simplified digital representation rather than the complex physical robot directly, achieving ease of operation while the complexity is managed in the virtual domain
Solution Approach 2:
The VR system acts as an intermediary layer between the operator and the industrial robot. The Cyber model serves as a mediator that translates simple VR controller inputs into complex robot motion commands, shielding the operator from the underlying system complexity while maintaining real-time control
2Manufacturing precision
If digital simulation environment is used for path planning and collision detection, then manufacturing precision is improved, but productivity decreases
Solution Approach 1:
The patent establishes continuous real-time bidirectional communication between the VR system and the industrial robot controller. Path planning and collision detection occur continuously in the virtual environment during robot operation, eliminating separate programming and debugging phases while maintaining manufacturing precision through ongoing virtual-physical synchronization
Solution Approach 2:
The system performs preliminary path planning and collision detection in the virtual Cyber model before executing motions in the physical robot. By pre-validating trajectories in the virtual environment, the system ensures manufacturing precision while reducing trial-and-error debugging time, thereby improving productivity
3Manufacturing precision
If command set planning and compilation process is implemented, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical programming approaches with a virtual reality-based interaction system. Instead of manually planning and compiling command sets through complex programming interfaces, operators directly manipulate the virtual robot model with intuitive VR controllers, achieving manufacturing precision through visual feedback while eliminating programming complexity
Data Source
AI summary
A real-time control system for industrial robots based on virtual reality (VR), including: a VR headset, a VR controller, a model construction module, a motion control module, a data communication system and a robot controller. Through the VR controller, a user can touch and drag an end of the gripper to move the robot in the Cyber environment. When the gripper moves into a bounding box of a control point, the data communication system is triggered, and a communication code corresponding to the control point is sent to the robot controller via a Unity engine script. After receiving the code, the robot controller sends the corresponding motion command such that the robot such that the robot moves in real time according to the control data.
