Robot Hand-Guiding Control with Integrated Enable Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot systems require operators to inconveniently manage separate hand-guiding and enable devices to ensure safety during hand-guiding operations, complicating the process and potentially compromising safety due to the need for simultaneous operation of multiple controls.
Innovation Solution
A robot system that integrates a mode designator to enable the enable device to function as both a hand-guiding and safety control mechanism, allowing for convenient and safe operation by designating the enable device to operate in hand-guiding or non-hand-guiding modes, thereby eliminating the need for separate controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate enable device and hand-guiding button are used to ensure safety, then safety is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines the enable device and hand-guiding button into a single integrated control unit. This unified device integrates the safety enable function and hand-guiding operation function, eliminating the need for separate controls while maintaining safety through integrated monitoring and control logic.
Solution Approach 2:
The integrated control unit serves multiple functions: it acts as both an enable device for safety monitoring and a hand-guiding button for robot control. This multi-functional design reduces the number of separate components needed while maintaining all necessary safety and operational capabilities.
2Reliability
If separate enable device and hand-guiding button are used, then safety monitoring is improved, but ease of operation deteriorates
Solution Approach 1:
The enable device and hand-guiding button are merged into a single control unit that performs both safety monitoring and hand-guiding operations. This integration allows the operator to perform both functions using one device, significantly improving ease of operation while maintaining safety monitoring capabilities.
3Reliability
If multiple controls must be pressed simultaneously, then safety is improved, but ease of operation deteriorates
Solution Approach 1:
The patent merges the enable device and hand-guiding button into a single integrated control unit. This eliminates the need for simultaneous pressing of multiple separate controls, as both functions are now accessible through one unified device, improving operational convenience while maintaining safety through integrated control logic.

AI summary
A robot system with a hand-guiding function is disclosed. The robot system selects the hand-guiding function or non-hand-guiding function of an enable device by a mode option mechanism during the operation of a teach mode or an automatic mode. When selecting the hand-guiding function, the enable device has both the enabling and the hand-guiding function to easily hand-guiding the robot to operate.
