Mobile Robot Path Planning With Travel Guidelines for Safe Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing public place guidance systems, such as electric signboards and kiosks, fail to provide personalized and efficient guidance services, particularly for individuals with difficulty using multimedia devices, and lack the ability to dynamically respond to user needs.
Innovation Solution
A moving robot system that receives user input for a guidance destination, creates a global route, and generates left and right travel guidelines to create a safe and optimal guidance route, utilizing a topological map and divided maps to improve service efficiency and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a kiosk provides information and services using multimedia devices, then information delivery capability is improved, but ease of operation deteriorates for users with difficulty using multimedia devices
Solution Approach 1:
The robot autonomously approaches users, detects their needs, and provides guidance information without requiring users to operate the kiosk. The system performs self-service by actively seeking out users who need assistance rather than waiting for user initiation.
Solution Approach 2:
The patent replaces the static mechanical kiosk interface with a mobile robotic system equipped with sensors and navigation capabilities. This substitution allows the system to dynamically approach users and provide information without requiring user interaction with complex multimedia controls.
2Loss of information
If electric signboards and guide information display boards provide information to users, then information delivery is improved, but adaptability to individual user needs deteriorates
Solution Approach 1:
The robot uses sensors to detect user presence, position, and potential needs, then adjusts its behavior and information delivery accordingly. This feedback loop enables the system to adapt to individual user situations rather than providing uniform information to all passersby.
Solution Approach 2:
The system transitions from static display boards to a dynamic mobile robot that can change its position, orientation, and information content based on real-time user needs. The robot dynamically adjusts its service provision based on detected user characteristics and situational context.
3Measurement precision
If a robot provides guidance services with detailed route planning, then guidance accuracy is improved, but computation time increases
Solution Approach 1:
The patent divides the global route into multiple local routes with intermediate destinations. This segmentation allows the system to compute and execute shorter, simpler path segments rather than calculating one complete complex route, reducing computation time while maintaining guidance accuracy through progressive destination updates.

AI summary
A mobile robot operation method according to an aspect of the present invention includes: a step for receiving a guidance destination input; a step for generating a global path to the received guidance destination; a step for generating a left travel guideline and a right travel guideline on the left side and the right side of the generated global path; and a step for generating a local path within a travelable range between the left travel guideline and the right travel guideline. Accordingly, the robot operation method may generate a safe and optimal guidance path when providing a guidance service.
