Robot Safety Parameter Switching for Faster Verification Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot control devices require cumbersome and repetitive parameter adjustments, particularly when changing the operating area or speed limits, necessitating frequent password inputs, which complicates the parameter adjustment process.
Innovation Solution
A robot control device with a function control unit that switches between safety and verification modes, allowing parameter adjustments in verification mode without password input, and securely applies verified parameters to safety mode with password confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password protection is implemented for parameter changes in safety function, then safety and security are improved, but operation complexity and adjustment time increase
Solution Approach 1:
The system divides parameter management into two distinct modes: verification mode for parameter adjustment and safety mode for protected operation. This segmentation allows password protection to be applied only where needed (safety mode) while enabling free adjustment in verification mode, thus resolving the contradiction between safety and ease of operation.
Solution Approach 2:
Parameter adjustments are performed in advance in verification mode before being applied to the safety function. This preliminary action allows all necessary adjustments to be made without password prompts during critical safety operations, improving both ease of operation and safety.
2Reliability
If parameter adjustment requires password input, then security is improved, but productivity and efficiency decrease
Solution Approach 1:
The system dynamically switches between verification mode (no password required) and safety mode (password protected) based on the operational context. This dynamic behavior allows efficient parameter adjustment when needed while maintaining security during safety-critical operations, resolving the productivity-security contradiction.
3Adaptability or versatility
If trial and error adjustment is allowed for robot parameters, then adaptability is improved, but time consumption increases
Solution Approach 1:
Multiple parameter adjustments can be prepared and verified in verification mode without time pressure or security interruptions. Once verified, these parameters are applied in safety mode, eliminating the need for repeated trial-and-error cycles during time-critical safety operations.

AI summary
The purpose of the present invention is to provide a robot control device capable of efficiently adjusting a parameter. This robot control device comprises: a first application unit that applies a setting parameter to a first safety parameter for verification in a verification mode; a first update unit that updates, on the basis of the first safety parameter, first safety information related to the robot in a verification function in the verification mode; a copy unit that copies the setting parameter; a second application unit that, after switching from the verification mode to the safety mode by a switch unit, applies the setting parameter copied by the copy unit to a second safety parameter; and a second update unit that updates, on the basis of the second safety parameter, second safety information related to the robot in a safety function in the safety mode.
