Guide Robot Device with Variable Display Direction for Multi-Person Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide robots can only efficiently guide one person to a destination at a time and lack sufficient detail in complex routes, posing challenges in understanding and safety, especially in preventing traffic accidents.
Innovation Solution
A guide robot system comprising multiple robots with a guide display unit, moving unit, destination position setting, unguided person position detection, and guide position calculation, allowing for efficient guidance of multiple persons with variable direction displays and communication between robots to relay guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one robot guides one person at a time, then the guidance is personalized and secure, but the efficiency is low and the number of persons guided per unit time is limited
Solution Approach 1:
The guidance process is segmented into two distinct modes: accompaniment mode for security-critical situations and map indication mode for efficiency. The system divides functionality between detailed real-time guidance (when needed) and overview route display (for general guidance), allowing one robot to serve multiple persons simultaneously through the map indication function while maintaining security through accompaniment when required
Solution Approach 2:
The robot dynamically switches between accompaniment mode and map indication mode based on route complexity and security requirements. The guidance approach is not static but adapts in real-time, transitioning from detailed real-time tracking for complex routes to efficient map-based indication for simple routes, optimizing both security and productivity
2Productivity
If the route is displayed on a map without accompanying the visitor, then the number of persons guided increases, but the guidance becomes difficult to understand for complex routes
Solution Approach 1:
The system applies different guidance qualities to different situations: comprehensive real-time accompaniment for complex routes where understanding is difficult, and simplified map indication for simple routes where ease of understanding is achieved through visual overview. The guidance quality is localized to match the specific route characteristics and user needs
3Reliability
If simple tracing is used to protect security, then the person is protected from traffic accidents, but detailed guidance is insufficient for complex routes
Solution Approach 1:
The robot dynamically adjusts the level of guidance detail based on route complexity assessment. For simple routes, basic tracing provides sufficient security protection. For complex routes, the system automatically transitions to detailed map indication with turn-by-turn directions, ensuring both security and comprehensive guidance information are maintained

AI summary
A guide robot device including a guide display unit for displaying the guide information to an unguided person and a moving unit adapted to move with the guide display unit mounted thereon is disclosed. The guide robot device further includes the guide display unit variable in the direction of the guide information, a destination position setting unit for setting the destination position of the unguided person, an unguided person position detection unit for detecting the position of the unguided person, and a guide position calculation unit for calculating the guide position as related to the destination position, the detected position of the unguided person and the distance from the guide robot device to the unguided person. The guide robot device is moved to the calculated guide position and the direction of the guide information determined.
