Robot Motion Limit Sets for Scene-Based Parameter Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot control systems require users to manually set numerous limit parameters for various scenes, increasing workload without considering factors like human cooperation and environmental conditions, leading to inefficiencies and potential safety risks.
Innovation Solution
A robot control system with a processor and memory that sets limit parameters based on input, utilizing a main parameter set and dependent sub-parameter sets, reducing the need for individual parameter setting across multiple scenes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users individually set limit parameters for each scene, then the robot motion can be precisely controlled for each specific scene, but the user workload increases significantly due to the enormous number of scenes
Solution Approach 1:
The patent segments the limit parameters into two distinct groups: common parameters that apply across multiple scenes and scene-specific parameters that are unique to each scene. This segmentation allows users to set common parameters once and reuse them across multiple scenes, significantly reducing the user workload while maintaining precise motion control for each specific scene through the scene-specific parameters.
Solution Approach 2:
The patent creates common parameter sets that can be universally applied across multiple scenes. These common parameters serve multiple functions by being reusable in different scene contexts, eliminating the need for users to re-set identical parameters for each scene while ensuring consistent motion control standards are maintained across all scenes that share these parameters.
2Reliability
If limit parameters are set for all possible scenes, then comprehensive motion control is achieved, but the system complexity increases due to the enormous number of scenes
Solution Approach 1:
The patent divides the parameter sets into common parameters and scene-specific parameters, creating a hierarchical structure that reduces system complexity. This segmentation allows the system to manage comprehensive motion control coverage without requiring separate complete parameter sets for every scene, as common parameters can be shared across multiple scenes.
Solution Approach 2:
The patent merges the common parameters across multiple scenes into a single reusable parameter set. This combining approach reduces the overall system complexity by eliminating redundancy, while still maintaining comprehensive motion control coverage through the combination of common and scene-specific parameters.
3Adaptability or versatility
If scene-specific parameters are introduced, then the adaptability to different scenes is improved, but the parameter set structure becomes more complex
Solution Approach 1:
The patent segments parameters into common and scene-specific categories, creating a structured hierarchy that improves scene adaptability while managing complexity. This segmentation allows the system to easily adapt to different scenes by selecting appropriate common parameter sets and configuring only the necessary scene-specific parameters, rather than managing entirely separate parameter sets for each scene.
Solution Approach 2:
The patent creates a dynamic parameter structure where the composition of parameter sets can flexibly adapt to different scenes. Users can dynamically select and combine common parameter sets with scene-specific parameters based on the actual scene requirements, providing high adaptability while maintaining a manageable structure through the common/scene-specific distinction.
