Guide Robot Speed Matching for Visually Impaired Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional guide robots for visually impaired individuals often have fixed moving speeds, making it difficult for them to adapt to different walking speeds or user preferences, which can lead to discomfort and inefficiency in navigation.
Innovation Solution
A guide robot equipped with a speed sensor to detect the user's walking speed and a driving device to adjust its speed accordingly, along with additional features like a handle control system, voice recognition, obstacle avoidance, and environmental mapping, ensuring the robot moves in sync with the user and provides assistance through voice reminders and remote communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the guide robot uses a fixed moving speed, then the device complexity is reduced, but the adaptability to different user walking speeds deteriorates
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed speed system to a dynamic speed adjustment system. The robot incorporates a speed sensor to detect user walking speed and a driving device to automatically adjust its moving speed in real-time, making the system adaptive to different user needs while managing complexity through automated control
Solution Approach 2:
The patent implements parameter changes by modifying the speed parameter from a fixed value to a variable that can be adjusted based on detected user walking speed. The driving device changes the robot's moving speed parameter dynamically to match the user's pace, improving adaptability without requiring complex manual intervention
2Ease of operation
If the guide robot automatically adjusts speed to match user walking speed, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the robot to automatically detect user walking speed and adjust its own moving speed without user intervention. The speed sensor and driving device work together to make the system self-regulating, improving ease of operation while the automated control manages the added complexity
Solution Approach 2:
The patent implements feedback through the speed sensor that continuously monitors user walking speed and provides information to the driving device. This closed-loop feedback system allows the robot to automatically adjust its speed to match the user's pace, improving ease of operation while managing complexity through automated control algorithms
