Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user identification methods for robot operations are vulnerable to spoofing, as ID cards and passwords can be compromised, posing safety risks during robot operations.
Innovation Solution
A machine learning device constructs a learning model for authenticating operators by acquiring operation data from a training operation panel, including movement and shape measurements, and uses supervised learning to identify operators, preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ID card or password authentication is used, then user identification can be implemented, but safety is compromised when ID cards are lent or passwords are revealed
Solution Approach 1:
The patent replaces traditional mechanical/authentication-based identification systems (ID cards, passwords) with a biometric recognition system that uses machine learning models to analyze operation patterns, body movement, and operational characteristics. This substitution eliminates the vulnerability of physical authentication media while providing more reliable safety assurance through unique biological characteristics.
Solution Approach 2:
The system utilizes the operator's own operational behavior and body characteristics as the authentication mechanism. Instead of relying on external authentication tools that can be compromised, the system leverages the operator's unique operational patterns and physical characteristics inherent to their interaction with the control device, making authentication inherent to the operator rather than dependent on external credentials.
2Reliability
If traditional ID authentication is used, then operation authorization can be granted, but spoofing of operators cannot be prevented
Solution Approach 1:
The patent replaces static authentication methods (ID cards, passwords) with dynamic biometric analysis that continuously monitors operational patterns, body movement, and interaction characteristics. This substitution provides more accurate authentication by verifying the operator's unique behavioral and physical characteristics rather than relying on static credentials that can be spoofed.
Solution Approach 2:
The system continuously monitors and analyzes operational patterns, providing real-time feedback on authentication status. The machine learning model processes ongoing operational data to verify operator identity throughout the operation process, not just at the initial authentication stage, thereby preventing spoofing while maintaining ease of operation.
3Measurement precision
If supervised learning with operation data is used, then operator identification accuracy is improved, but data processing complexity increases
Solution Approach 1:
The patent implements a two-stage approach where a machine learning model is constructed in advance through supervised learning using labeled operation data. This preliminary action creates a trained model that can then perform rapid, accurate identification during actual operation. The complex data processing and model training are performed beforehand, allowing for efficient real-time authentication without excessive complexity during operational use.
Data Source
AI summary
A machine learning device capable of preventing spoofing of an operator to secure safety during an operation of a robot is provided. A machine learning device includes: an input data acquisition means that acquires, as input data, operation data including a measurement value related to a movement of at least a portion of a body of the operator and a shape of the body, detected when the operator is caused to perform a predetermined operation associated with a training operation panel of the robot controller; a label acquisition means that acquires identification information of the operator as a label; and a learning means that constructs a learning model that performs user identification for authenticating operators of the robot controller by performing supervised learning using a pair of the input data and the label as training data.
