Serving Robot Character Control for Personalized Voice Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing serving robots provide sound information using a uniformly set voice, failing to offer unique voices and thus lack the personal touch of human service.
Innovation Solution
A method to control serving robots by generating multiple characters with distinct voices and visual information, allowing differentiation among robots based on their roles and surroundings, enhancing the perceived human-like service experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a uniformly set voice is used for all serving robots, then the system is simple to manage, but the customer experience lacks personalization and human-like service perception
Solution Approach 1:
The patent segments the monolithic voice system into individual character modules for each robot. Each serving robot is assigned a unique character with distinct voice properties (pitch, tone, speaking style), allowing personalized communication while maintaining manageable system complexity through modular character design
Solution Approach 2:
The patent changes voice parameters (pitch, tone, speaking style) to create distinct characters for different robots. By adjusting these acoustic parameters, each robot develops a unique voice identity that enhances personalization without requiring complete system redesign
2Ease of operation
If each serving robot has a unique voice character, then the customer experience becomes more personalized and human-like, but the system complexity increases due to multiple character management requirements
Solution Approach 1:
The patent creates simplified digital character models that replicate human voice characteristics. Each robot's character is a copy of essential human communication traits (pitch, tone, style) stored as configurable parameters, enabling realistic interaction without complex human-level cognitive systems
Solution Approach 2:
The character system serves multiple functions simultaneously: it provides unique voice identification, conveys emotional tone, establishes robot personality, and enables differentiated customer interaction. This multi-functionality reduces the need for separate systems for each purpose
3Adaptability or versatility
If serving robots are grouped by role with different characters, then the service differentiation is improved, but the character generation and assignment process becomes more complex
Solution Approach 1:
The patent pre-defines character templates associated with specific robot roles (e.g., formal characters for waiters, friendly characters for guides). During system deployment, characters are automatically assigned based on robot function, eliminating the need for manual customization and simplifying the deployment process

AI summary
A method for controlling a serving robot is provided. The method includes the steps of: generating at least one character on the basis of at least one property related to a voice, and determining a character to be applied to a serving robot from among the at least one generated character; and generating at least one piece of visual information corresponding to the determined character, and determining a piece of visual information to be applied to the serving robot from among the at least one generated piece of visual information.
