Robotic Arm Axis Visualization for Collision-Aware Collaboration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Human-robot collaboration is impaired due to involuntary monitoring of robotic arms and unexpected movements, leading to collisions and reduced cycle times.
Innovation Solution
A method and system that visually indicate imminent adjustments of a robotic arm's axis, particularly the axis closest to the base, to allow humans to focus on their tasks without constant observation, using visualization means such as LEDs to predict and display the axis's position and movement in the workspace.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If humans continuously monitor the robotic arm to ensure safety, then collision risk is reduced, but human concentration on the primary task deteriorates and cycle time increases
Solution Approach 1:
The system performs preliminary action by visually indicating the imminent adjustment of the robotic arm's axis before the movement occurs. The visualization means displays the current position and imminent position of the axis, allowing humans to anticipate movements in advance without needing to continuously monitor the robotic arm, thus maintaining safety while improving productivity
Solution Approach 2:
The visualization means acts as an intermediary between the robotic arm's control system and the human operator. It translates the robotic arm's internal state and planned movements into visual information that humans can easily perceive and understand, enabling safe collaboration without requiring constant human attention
2Reliability
If humans continuously observe the robotic arm movements, then safety is improved, but human concentration on their task deteriorates
Solution Approach 1:
The system provides advance visual information about the robotic arm's imminent movements through the visualization means. By showing the current position and predicted position of the axis before movement occurs, humans can mentally prepare and maintain concentration on their primary task while still being aware of robotic arm movements for safety
Solution Approach 2:
The visualization means provides continuous feedback to humans about the robotic arm's state and intended movements. This feedback loop allows humans to understand robotic arm behavior without active monitoring, improving safety while maintaining ease of operation

AI summary
A method for operating a robotic arm using a first visualization device includes visually indicating, on the robotic arm and/or in the workspace of the robotic arm and/or on a work surface below the robotic arm, an imminent adjustment of at least one axis of the robotic arm, in particular of at least one axis closest to the robotic arm base.
