Robot Access Control Using Target Codes for Offline Licensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot as a service (RAAS) systems face challenges in efficiently managing and authenticating robot licenses, especially in offline environments, which affects the transparency, safety, and maintenance of robot operations.
Innovation Solution
A system and method for controlling robots that utilize a target code management scheme, where a robot control server generates and manages digital licenses based on user requests, using symmetric key encryption and different verification methods depending on the connection state between the robot and the server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If digital licenses are managed through cloud services, then license issuance and management efficiency is improved, but reliability deteriorates in offline environments where cloud connectivity is unavailable
Solution Approach 1:
The system performs preliminary actions by storing license information and authentication data in the robot control server before offline operation is needed. When the robot goes offline, it can still authenticate using pre-stored license data and target codes, eliminating the need for real-time cloud connectivity for basic authentication operations.
Solution Approach 2:
The patent introduces target codes as intermediaries that bridge the cloud-based license management system and offline robot operation. These target codes contain encoded license information that can be verified locally without cloud connectivity, while still maintaining the security and control of the centralized license management system.
2Reliability
If separate authentication schemes are used for online and offline services, then reliability is improved for each specific environment, but device complexity increases
Solution Approach 1:
The patent implements a universal target code-based authentication system that functions across both online and offline environments. The same target code structure and verification mechanism are used regardless of connectivity status, eliminating the need for separate authentication schemes while maintaining reliability in both contexts.
Solution Approach 2:
The system merges online and offline authentication into a unified process using target codes. The robot control server generates target codes that work for both cloud-connected and offline operations, combining the benefits of centralized license management with the flexibility of offline operation into a single authentication mechanism.
3Reliability
If traditional license management methods are used, then security is maintained through centralized control, but ease of operation deteriorates due to complex registration and authentication procedures
Solution Approach 1:
The system creates simplified copies of license information in the form of target codes that can be easily captured and verified. Instead of requiring users to manually input or manage complex license keys, the target code can be captured via camera or scanner, dramatically simplifying the registration process while maintaining the security of centralized license management.
Solution Approach 2:
The patent replaces manual license registration and authentication procedures with automated optical recognition systems. The robot's camera or scanner captures the target code, and the system automatically verifies it against the license database, eliminating the need for users to manually enter or manage complex authentication credentials.

AI summary
A system for controlling a robot and a method thereof include a robot control server, and a robot, wherein the robot control server may receive a request for issuance of a target code related to access authority to the robot from a user operating the robot, and wherein the robot may identify the target code input by the user, and receive a command from the user based on validity of the target code being verified.
