Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing serving robot systems are unable to provide sound information to customers using unique voices, resulting in a lack of personalization and human-like interaction.
Innovation Solution
A method and system for controlling serving robots that generate unique voices for each robot based on character determination and visual information, allowing the robots to provide personalized sound information to customers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If serving robots use uniformly set voice for sound information, then the system is simple and easy to implement, but the customer experience lacks personalization and human-like interaction
Solution Approach 1:
The patent applies parameter changes by modifying voice characteristics (pitch, tone, speed, volume) to create unique voices for different robots. The control server generates multiple voice parameters and applies them to different robots, enabling personalized sound information delivery without requiring complex hardware modifications. This resolves the contradiction by achieving adaptability through software-based parameter adjustment rather than hardware complexity.
2Adaptability or versatility
If serving robots generate unique voices for each robot, then customer experience is enhanced with human-like interaction, but the system complexity increases
Solution Approach 1:
The patent introduces a control server as an intermediary between the robot control systems and the voice generation process. The control server handles character determination, voice parameter generation, and visual information creation, offloading complexity from individual robots. This mediator approach enables unique voice capabilities while keeping the robot hardware relatively simple, as the complex processing occurs centrally on the server.
Solution Approach 2:
The patent uses copying by generating visual information (such as character images or avatars) that corresponds to each unique voice. Instead of creating entirely new hardware or complex software systems for each robot, the system copies and adapts base templates with different parameters to create unique identities. This reduces complexity while maintaining the ability to provide personalized human-like interaction.
3Reliability
If serving robots provide sound information with personalized characters, then customer satisfaction increases, but the processing time and system resources increase
Solution Approach 1:
The patent applies preliminary action by pre-generating and storing multiple voice parameters and visual information templates on the control server before they are needed. When a robot needs to provide sound information, the system retrieves and applies pre-prepared character data rather than generating everything in real-time. This reduces processing time while maintaining personalized quality, as the heavy computational work is done in advance.

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.
