Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods fail to effectively post-install a data collection function on existing robot controllers to arbitrarily select and collect various data on robot operations, limiting the accuracy of lifetime and fault diagnoses of drive mechanisms.
Innovation Solution
A data collection system with a data collection condition setting unit and a data storage unit, housed in a shared memory substrate that can be mounted on an expansion slot of the robot controller, allowing for customizable data collection and transmission of robot operation data via a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a WEB server is implemented inside a robot controller to gather data via communication networks, then data collection capability is improved, but the ability to post-install arbitrary data collection functions on existing controllers deteriorates
Solution Approach 1:
The data collection system is segmented into a removable substrate that can be independently mounted on the robot controller. This substrate contains the data collection condition setting unit and data storage unit, separating the data collection functionality from the main controller architecture. This segmentation enables post-installation of data collection functions without modifying the core controller system, thereby maintaining adaptability while achieving automation.
Solution Approach 2:
The substrate is designed with universal compatibility to be mounted on existing robot controllers through standard expansion slots. The data collection condition setting unit can arbitrarily select and collect various types of robot operation data, making the system multi-functional and adaptable to different data collection needs without requiring controller-specific implementations.
2Reliability
If data collection functions are built into the robot controller, then data collection reliability is improved, but the ease of post-installation on existing controllers deteriorates
Solution Approach 1:
By segmenting the data collection function into a separate mountable substrate, the system achieves reliable data collection through dedicated hardware while maintaining ease of post-installation. The substrate can be physically installed on existing controllers without requiring complex integration work, combining reliability with installation simplicity.
3Measurement precision
If arbitrary data selection and collection is enabled, then diagnostic accuracy is improved, but system complexity deteriorates
Solution Approach 1:
The data collection condition setting unit is extracted as a separate functional module on the substrate, allowing arbitrary selection of robot operation data for collection. This extraction enables high diagnostic accuracy through selective data collection while containing system complexity within the modular substrate rather than distributing it throughout the entire controller system.
Data Source
AI summary
This system is a data collection system collecting a robot operation-related data/signal from a robot controller. The data collection system includes a data collection condition setting unit setting a collection condition of the robot operation-related data/signal from the robot controller and a data storage unit storing the robot operation-related data/signal collected from the robot controller. A shared memory inside which the data storage unit and the data collection condition setting unit are formed is formed in a substrate which can be mounted on an expansion slot of the robot controller. According to this system, a data collection function can be post-installed to an existing robot controller so as to arbitrarily select and collect various data on the robot operation.
