Remote Robot Control with Restricted Secondary Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ensuring safety when an operator remotely operates a robot system, particularly when using secondary operation terminals that may be operated by less experienced users.
Innovation Solution
Implementing a robot system with a primary operation terminal for overall control and a secondary operation terminal with restricted capabilities, ensuring that operations performed by the secondary terminal are limited compared to the primary, thereby preventing unsafe actions by less experienced operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple operation terminals are provided for remote operation of the robot, then the ease of operation is improved, but the safety deteriorates due to potential erroneous operations by less experienced users
Solution Approach 1:
The patent applies local quality by providing different operation terminals with different functional capabilities. The first operation terminal provides full operation capabilities, while the second operation terminal provides only restricted operation capabilities. This allows each terminal to be optimized for its specific use case, improving ease of operation for monitoring tasks while maintaining safety through restricted capabilities for less experienced users.
Solution Approach 2:
The patent segments the operation terminal functionality into two distinct terminals: a first operation terminal with full control capabilities and a second operation terminal with restricted capabilities. This segmentation allows the system to serve multiple operational needs simultaneously while preventing unsafe operations through the restricted terminal's limited functionality.
2Adaptability or versatility
If full operation capabilities are provided to all terminals, then the adaptability is improved, but the safety deteriorates due to increased risk of erroneous operations
Solution Approach 1:
The patent implements local quality by assigning different operational adaptability levels to different terminals. The first operation terminal maintains full adaptability for comprehensive robot control, while the second operation terminal has restricted adaptability suitable for monitoring and basic operations. This resolves the contradiction by providing adaptability where needed while maintaining safety through restricted access elsewhere.
Solution Approach 2:
The patent segments operational adaptability across multiple terminals, allowing the system as a whole to be highly adaptable while individual terminals have appropriate capability restrictions. This enables the system to adapt to different operational scenarios without compromising safety, as each terminal's adaptability is matched to its intended use case.
3Reliability
If restricted operations are implemented on secondary terminals, then the safety is improved, but the ease of operation deteriorates due to limited functionality
Solution Approach 1:
The patent applies local quality by ensuring that the second operation terminal, which is used for monitoring and basic operations, has restricted but sufficient functionality for its specific purpose. The restriction is not arbitrary but tailored to the terminal's intended use, maintaining ease of operation for appropriate tasks while ensuring safety through capability limitations.
Solution Approach 2:
The patent segments operational capabilities so that the second terminal provides ease of operation for monitoring and communication tasks without requiring full robot control capabilities. This segmentation ensures that users can easily perform their specific tasks while the system maintains safety through the inherent capability restrictions.
4Reliability
If different operation capabilities are assigned to different terminals, then the safety is improved, but the device complexity increases due to multiple terminal configurations
Solution Approach 1:
The patent segments the operation terminal system into two distinct terminals with clearly defined capability sets. This segmentation, while creating multiple configurations, actually simplifies the overall system architecture by providing clear separation of concerns and well-defined interfaces, making the complexity manageable and the safety restrictions enforceable.
Solution Approach 2:
The patent applies universality by designing the operation terminals to handle multiple functions (monitoring, communication, control) within their respective capability boundaries. This multi-functionality reduces the need for additional specialized devices, managing device complexity while maintaining safety through the universal design patterns applied to both terminals.

AI summary
A first exemplary aspect is a robot system includes: a robot configured to perform a predetermined operation; a first operation terminal configured to remotely operate the robot; and a second operation terminal configured to remotely operate the robot, the second operation terminal being provided separately from the first operation terminal. An operation capable of being performed by the second terminal to operate the robot is restricted as compared with that performed by the first operation terminal.
