Augmented Reality Display for Robot Motion Area Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators cannot visually recognize the motion area of a robot, leading to potential errors in entering the area and reducing working efficiency.
Innovation Solution
An augmented reality display device comprising a camera, display unit, and display control unit that displays an image of the robot and its motion area, using three-dimensional recognition models and real-time data to generate an augmented reality image, allowing operators to visually check the robot's motion area and trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety monitoring control is performed by setting motion area around the operator, then safety is improved, but working efficiency deteriorates due to operator errors
Solution Approach 1:
The patent introduces an augmented reality display as an intermediary between the robot system and the operator. The display overlays visual information about the robot's motion area and trajectory onto the operator's field of view, serving as a mediator that communicates robot status without requiring the operator to actively monitor or interpret raw sensor data.
Solution Approach 2:
The system implements feedback by displaying real-time information about the robot's motion area and trajectory to the operator. This allows the operator to see the robot's planned path and current position, enabling them to understand when it is safe to enter the motion area and when to wait, thus reducing unnecessary stops.
2Ease of operation
If operator enters motion area without visual recognition, then ease of operation is maintained, but safety deteriorates due to accidental entry
Solution Approach 1:
The augmented reality display uses color-coded visualization to indicate the robot's motion area and trajectory. Different colors represent different states (e.g., active motion area, safe zones, trajectory path), providing intuitive visual cues that allow operators to quickly understand robot status without complex interfaces or training.
Solution Approach 2:
The patent adds a visual dimension to safety monitoring by overlaying augmented reality graphics onto the operator's natural field of view. Instead of requiring the operator to look at separate monitors or control panels, the motion area and trajectory information is displayed in the same spatial dimension where the operator works, making safety information as accessible as the physical environment itself.
3Device complexity
If robot motion area is not visualized, then device complexity is reduced, but information availability deteriorates
Solution Approach 1:
The system creates a visual copy or representation of the robot's motion area and trajectory and displays it through augmented reality. Instead of requiring complex physical markers or changing the actual environment, the patent generates a digital overlay that replicates the spatial information about where the robot will move, providing complete information availability without adding physical complexity to the robot system.
