Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot control devices are not easily interchangeable across different models or versions, requiring manual adjustment for firmware, application software, and individual variability, limiting flexibility and efficiency in robot replacements and upgrades.
Innovation Solution
A robot control device with a verification process at startup that compares essential data sets stored in non-volatile memory and RAM, overwriting mismatched data to ensure seamless replacement and compatibility, regardless of firmware or application software versions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If robot control devices are prepared for each model with model-specific configuration information, then control accuracy for each model is improved, but device complexity and difficulty of replacement increase
Solution Approach 1:
The patent creates a universal robot control device that can control multiple robot models by separating common control functions (stored in the robot control device) from model-specific configuration information (stored in the robot itself). This allows one control device to serve multiple models without sacrificing control accuracy.
Solution Approach 2:
The patent extracts model-specific configuration information from the robot control device and places it in the robot's storage unit. This separation removes the burden of model-specific data from the control device, enabling universal compatibility while maintaining precise control through retained common control programs.
2Measurement precision
If model-specific configuration information is stored in the robot control device, then control accuracy is improved, but ease of operation and replacement are worsened
Solution Approach 1:
The robot automatically provides its own model-specific configuration information from its internal storage unit when connected to the control device. This self-service approach eliminates the need for operators to manually input or transfer configuration data, making replacement straightforward while maintaining control accuracy through automatic data retrieval.
3Measurement precision
If individual variability data is stored in the robot control device, then control precision for individual robots is improved, but ease of operation and flexibility are worsened
Solution Approach 1:
The patent extracts individual variability data (such as offset values) from the robot control device and stores it in the robot's storage unit. This allows the control device to remain generic and easy to replace, while each robot carries its own customization data, maintaining control precision without operational complexity.
4Reliability
If robot control devices are designed for specific models, then reliability for intended use is improved, but adaptability to different models is worsened
Solution Approach 1:
The patent designs the robot control device to be universal across multiple models by retaining only common control functions, while model-specific adaptations are handled by the robot's own stored configuration information. This achieves both reliability through proven common control logic and adaptability through model-specific data provided by the robot itself.
Data Source
AI summary
A group of programs and data necessary to control the robot is referred to as an essential data set, the essential data set already stored in a non-volatile memory provided in a robot and the essential data set stored in a non-volatile storage unit of a robot control device are compared at a start-up of the robot control device, and when a mismatch is detected, the essential data set stored in the robot control device is overwritten with the essential data set on the robot side.
