Collaborative Robot Control for Dominant-Hand and Height Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collaborative robot systems fail to efficiently adapt to individual human worker attributes, such as dominant hand or height, leading to reduced work efficiency and increased worker fatigue.
Innovation Solution
A robot system that includes a control device capable of selecting actions based on special information of the user, such as attributes like dominant hand or height, to optimize work efficiency and reduce fatigue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot system uses a fixed action sequence for all workers, then the control system remains simple, but work efficiency decreases and worker fatigue increases due to lack of adaptation to individual attributes
Solution Approach 1:
The system changes operational parameters by selecting different action sequences based on detected worker attributes (e.g., dominant hand, height). The control device stores multiple action sequences with different parameters and selects the appropriate sequence based on worker characteristics, thereby improving work efficiency without requiring a completely complex new system architecture
Solution Approach 2:
The robot system transitions from a static, fixed action sequence to a dynamic system that can adapt its behavior based on real-time detection of worker attributes. The control device dynamically selects action sequences based on worker characteristics, enabling the system to optimize performance for each individual worker while maintaining a manageable control structure
2Ease of operation
If the robot system adapts to individual worker attributes, then work efficiency improves, but the device complexity increases due to multiple action sequences and attribute detection requirements
Solution Approach 1:
The system performs self-configuration by automatically detecting worker attributes and selecting appropriate action sequences without requiring manual programming or complex setup procedures. The control device autonomously adapts to each worker's characteristics, improving ease of operation while keeping the control system relatively simple through automated decision-making
3Duration of action of moving object
If the robot system uses generic actions for all workers, then the control system remains simple, but worker fatigue increases during prolonged work periods
Solution Approach 1:
The system modifies operational parameters by selecting action sequences optimized for individual worker attributes. Different action sequences are stored with parameters tailored to specific worker characteristics (e.g., right-handed vs. left-handed workers), enabling the robot to maintain optimal performance over extended periods and reduce fatigue without requiring complete system redesign
