Robot Operation Authority Switching Across Multiple Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot systems face challenges in quickly and easily switching operation authority between terminals without re-registration, particularly in manufacturing sites and households, due to interference issues and the need for ID information re-entry, which can lead to operational delays and user difficulties.
Innovation Solution
A robot system that grants operation authority to a single operation terminal based on a predetermined authority code, allowing seamless switching without re-registering ID information, and includes features like authority code verification and cancellation processing to ensure safety and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ID information re-registration is required when switching operation terminals, then operation authority can be securely transferred, but time consumption and operational complexity increase
Solution Approach 1:
The robot controller pre-stores multiple ID information sets (including backup terminal IDs) in advance. When the primary operation terminal cannot be used, the controller automatically detects this and transfers authority to a pre-configured backup terminal without requiring re-registration, thus resolving the contradiction between security and time consumption
Solution Approach 2:
The robot controller autonomously performs the authority transfer process by automatically detecting terminal unavailability and switching to backup terminals using pre-stored ID information. This self-service mechanism eliminates the need for manual re-registration operations, reducing both time loss and operational complexity while maintaining security
2Adaptability or versatility
If multiple operation terminals can connect to the robot controller, then operational flexibility increases, but interference between terminals and control conflicts occur
Solution Approach 1:
The system dynamically manages terminal connection states by establishing clear active/standby relationships. The robot controller monitors terminal statuses and automatically activates pre-designated backup terminals when primary terminals become unavailable, enabling flexible switching while preventing simultaneous active connections that cause interference
Solution Approach 2:
The robot controller acts as an intermediary that manages the relationship between multiple terminals and the robot. It maintains an authority hierarchy where only one terminal can issue commands at a time, while backup terminals remain in standby mode with pre-configured authority, thus enabling flexibility without causing operational interference
3Reliability
If manual re-registration of ID information is required, then system security is maintained, but ease of operation decreases
Solution Approach 1:
ID information for backup terminals is registered and stored in advance in the robot controller. This preliminary configuration maintains system security by ensuring only authorized terminals can connect, while simultaneously improving ease of operation by eliminating the need for manual re-registration during terminal switching
Solution Approach 2:
The robot controller automatically manages the terminal switching process using pre-stored ID information. This self-service approach maintains security through automated authentication while greatly simplifying the user experience, as no manual intervention is needed during terminal transitions

AI summary
A robot system includes: a robot; a plurality of operation terminals that receive an input of a password for acquiring operation authority of the robot and an operation input for operating the robot from a user; and a robot controller communicable with the operation terminals. The robot controller drives, in a controlled manner, the robot according to operation from a single operation terminal among the operation terminals. The robot controller includes a password storage unit that stores a password for granting operation authority of the robot to the operation terminal. The robot controller further includes an operation authority grant processing unit that grants operation authority of the robot to a single operation terminal to which a proper predetermined password stored in the password storage unit is first input in a state in which operation authority of the robot is not granted to any operation terminal.
