Mobile Robot Head Display for Personalized Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional guidance systems in public places, such as airports and department stores, are limited in providing personalized information and services, as they are unidirectional and often require user interaction, which can be inconvenient for those with difficulty using multimedia devices.
Innovation Solution
A mobile robot equipped with a rotatable human-like head display, RGBD sensors, and a control unit that allows for voice command recognition and autonomous navigation, enabling it to provide personalized guidance and services while moving through public spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional electronic boards and guide boards are used for providing information, then information can be displayed to users, but the system cannot meet individual user demands and provides only unidirectional information transfer
Solution Approach 1:
The mobile robot system incorporates sensors to detect user presence, position, and interaction preferences, enabling the system to receive feedback about user needs and adjust information delivery accordingly. The robot can sense user direction, pause to allow information intake, and adapt its guidance based on observed user behavior, transforming the unidirectional information flow into a bidirectional interactive system.
Solution Approach 2:
The robot system autonomously navigates to users, positions itself optimally for interaction, and automatically provides personalized guidance information without requiring user manipulation of complex interfaces. The system serves itself by autonomously detecting user needs, moving to appropriate locations, and delivering customized information based on sensor input, eliminating the need for users to operate complex kiosk interfaces.
2Adaptability or versatility
If kiosks with multimedia devices are introduced for user interaction, then information can be provided in a more engaging manner, but users with difficulty using multimedia devices find it inconvenient
Solution Approach 1:
The mobile robot serves as an intermediary between the information system and the user, particularly for users who struggle with direct multimedia device operation. Instead of requiring users to directly interact with complex kiosk interfaces, the robot mediates by autonomously navigating to users, displaying information on its own display unit, and providing guidance through voice and visual cues, thereby simplifying the interaction interface for less tech-savvy users.
Solution Approach 2:
The system replaces complex mechanical interaction interfaces (touch screens, buttons, keyboards) with more accessible communication channels. The robot uses voice output for information delivery, visual displays for guidance, and automatic positioning through autonomous navigation, substituting the need for users to physically interact with complex multimedia devices with more intuitive and accessible communication methods.
3Ease of operation
If a mobile robot is designed to provide personalized guidance services, then user convenience and accessibility are enhanced, but the device complexity increases
Solution Approach 1:
The mobile robot is designed as a multi-functional platform that integrates navigation, sensing, information display, and communication capabilities into a single autonomous system. The same robot can provide guidance to different types of users in various public spaces, handling diverse tasks from basic information delivery to complex route guidance, thereby amortizing the complexity across multiple functions and use cases rather than requiring separate specialized systems.

AI summary
A method of operating a mobile robot includes displaying, on a display unit, a photographing menu including a first photographing item for allowing the mobile robot to perform a specific motion for photographing and a second photographing item for allowing the mobile robot to photograph a user, displaying a screen for guiding a motion setting of the mobile robot on the display unit when the first photographing item is selected, performing, by the mobile robot, a corresponding motion based on an input motion setting for a first reference time when the motion setting of the mobile robot is input, and displaying a result screen on the display unit after the first reference time has elapsed.
