Robot Control System Emotion Recognition Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integrated robot systems that combine conversation and service execution functions struggle to accurately recognize user emotions and provide appropriate services, as they often require a human-like shape for emotion extraction, limiting their service capabilities and user interaction.
Innovation Solution
A robot control system featuring humanoid conversation robots that can change body shape and lighting to express emotions, combined with service execution robots, allows for better emotion recognition and service provision through a network of sensors and a server, enabling accurate user request and emotion recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both conversation function and service execution function are integrated into one robot, then the robot can interact with users, but it is difficult to provide services accurately in accordance with user requests and emotions
Solution Approach 1:
The system divides the robot into two specialized types: humanoid conversation robots that excel at emotion recognition through human-like shapes and expressions, and service execution robots that perform tasks. This segmentation allows each robot type to optimize for its specific function, resolving the contradiction between service accuracy and emotion recognition accuracy that plagues integrated single-robot systems.
2Measurement precision
If the robot shape is changed to be closer to human shape for emotion extraction, then emotion recognition is improved, but the ability to provide various types of service is reduced
Solution Approach 1:
The patent segments the robot population into humanoid conversation robots with human-like shapes optimized for emotion recognition, and service execution robots with shapes optimized for specific tasks. This allows emotion recognition accuracy to be improved in conversation robots without compromising service capabilities in execution robots, as each type is specialized for its primary function.
Solution Approach 2:
The system creates a universal robot ecosystem where different robot types work together through a centralized control system. The humanoid conversation robots and service execution robots, along with other specialized robots, form a multi-functional system that can handle both emotional interaction and diverse service tasks through coordinated operation rather than requiring each individual robot to be universally capable.
3Adaptability or versatility
If various types of functions are incorporated into the robot to improve service execution function, then service capability is enhanced, but the robot shape becomes different from human shape making it difficult to recognize user emotion
Solution Approach 1:
The patent resolves this contradiction by segmenting functions across different robot types. Service execution robots incorporate specialized functions and shapes optimized for specific tasks, while humanoid conversation robots maintain human-like shapes for emotion recognition. The centralized control system coordinates these specialized robots, allowing the system as a whole to achieve both enhanced service execution and accurate emotion recognition without requiring each individual robot to possess all functions.

AI summary
A robot control system (10) includes a humanoid conversation robot (210, 230) that has a conversation with a user (50), at least one service execution robot (240, 260) that provides a service to the user, a recognition unit (222) that recognizes a request and an emotion of the user through the conversation between the user and the humanoid conversation robot, and a determination unit (407, 408) that determines a service which is to be provided to the user and a service execution robot which is to execute the service among the at least one service execution robot according to the request and the emotion of the user. The service execution robot determined by the determination unit executes the determined service.
