Robot Teaching Device Switching Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing robot systems, operators face difficulties in efficiently switching between multiple teaching devices that can execute active tasks, as they need to manually manage and disconnect active tasks, requiring a deep understanding of the internal functions of the robot control device.
Innovation Solution
A robot system where the robot control device automatically stops one teaching device from executing active tasks and establishes communication with another teaching device to allow seamless task switching, including the option to maintain passive task execution and permit or deny connection requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If one teaching device is connected to the robot control device for executing active tasks, then active task execution is enabled, but switching to another teaching device requires manual disconnection and reconnection operations
Solution Approach 1:
The robot control device preliminarily determines whether an active task is currently being executed by another teaching device before establishing a new connection. This preliminary check and automatic disconnection action eliminates the need for manual intervention, allowing operators to switch teaching devices simply by connecting without worrying about existing active task connections.
2Reliability
If manual disconnection of active tasks is required before switching teaching devices, then communication conflict is prevented, but operator understanding of internal functions is required
Solution Approach 1:
The robot control device performs self-service by automatically detecting active task execution status and autonomously disconnecting the previous teaching device when a new connection is attempted. This eliminates the need for operators to understand internal communication protocols or manually manage active task states, while still ensuring reliable conflict prevention.
3Ease of operation
If automatic disconnection is implemented when switching teaching devices, then switching simplicity is improved, but passive task execution may be interrupted
Solution Approach 1:
The patent segments task execution into two independent categories: active tasks (robot operation) and passive tasks (monitoring, display). When switching teaching devices, only active tasks are automatically disconnected, while passive tasks continue to run. This segmentation allows simple switching operations without interrupting background monitoring and display functions.

AI summary
It is assumed that when a first teaching device is communicating with an active task unit in a robot control device, a second teaching device transmits a request to connect to the active task unit, to the robot control device. In such a case, the robot control device is configured to stop the first teaching device executing active tasks, and establish communication between the second teaching device and the active task unit of the robot control device which allows active tasks to be executed thereby.
