Cylindrical Robot Operation Unit with Groove-Protrusion Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot operation systems face challenges in stable attachment and operation of touch panel monitors due to arm attitudes, leading to difficulties in direct teaching, especially when the monitor is hard to view.
Innovation Solution
A robot operation apparatus with a cylindrical operation unit, communication unit, and detachable attachment means, featuring a rotation stopping portion with nonslip protrusions that securely attach to the robot's outer surface, allowing for stable operation regardless of arm curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch panel monitor is detachably attached to the arm near the robot, then the direct teaching can be performed near the robot, but the monitor becomes difficult to view when the arm attitude changes
Solution Approach 1:
The operation unit is designed to rotate together with the arm when the arm attitude changes, maintaining a fixed relative position between the operation unit and the arm. This dynamic rotation ensures the monitor remains accessible and viewable regardless of arm position, resolving the contradiction between proximity for operation and viewability across different attitudes.
2Adaptability or versatility
If the operation unit is detachably attached to the cylindrical outer surface of the robot, then the attachment position can be adjusted, but rotation and backlash occur during operation
Solution Approach 1:
The attachment system is divided into separate components: a groove formed in the cylindrical outer surface and a corresponding protrusion on the operation unit. This segmentation allows the operation unit to be detached and reattached at different positions while the groove-protrusion interface prevents rotation and backlash, simultaneously achieving position flexibility and attachment stability.
Solution Approach 2:
The groove acts as an intermediary structure between the robot's outer surface and the operation unit. This intermediate feature provides both the flexibility for detachable repositioning and the mechanical constraint to eliminate rotation and backlash, resolving the contradiction between adaptability and reliability.
3Reliability
If the operation unit is firmly attached to the arm, then stability is improved, but the attachment structure becomes more complex
Solution Approach 1:
Instead of making the entire attachment structure complex, the invention applies a simple groove-protrusion feature locally at the attachment interface. This localized feature provides firm attachment and eliminates rotation without requiring complex mechanisms throughout the entire attachment system, achieving stability while maintaining simplicity.

AI summary
A collaborative robot operation apparatus includes an operation unit that is operated by an operator in direct teaching of a robot including a cylindrical outer surface at least in a part, a communication unit that communicates operation information to the operation unit, to a control apparatus of the robot, and an attachment portion that detachably attaches the operation unit on the outer surface of the robot. The operation unit includes a rotation stopping portion between the outer surface of the robot and the operation unit.
