Mobile Body Control Modes for User Following and Position-Ahead Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile body control technologies for robots and self-propelled vehicles lack advanced features to assist human movement in crowded areas like amusement facilities, commercial spaces, and airports, with a need for improved usability, safety, and adaptability in guiding and following users.
Innovation Solution
A mobile body control device equipped with processors and memory that acquires sensor information, sets control modes, and controls travel based on detected persons, allowing the mobile body to follow users or move to designated points, with features like vein authentication, machine learning for behavior prediction, and multiple operational modes for enhanced usability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile body travels together with the specific person in follow mode, then the assistance in movement is improved, but the ability to position itself before the user is lost
Solution Approach 1:
The mobile body dynamically switches between follow mode and position-ahead mode based on user needs. The system transitions from a static single-mode operation to a dynamic multi-mode operation, allowing the mobile body to adapt its behavior (traveling with user vs. positioning before user) to provide versatile assistance.
2Measurement precision
If the mobile body moves to a designated point before the user, then the positioning accuracy is improved, but the real-time following capability is reduced
Solution Approach 1:
The mobile body performs preliminary positioning action by moving to the designated point before the user arrives. This preliminary action ensures accurate positioning in advance, allowing the system to maintain both high positioning accuracy and respond quickly when the user approaches, as the mobile body is already in the correct position.
3Adaptability or versatility
If multiple control modes are implemented, then the adaptability to different user needs is improved, but the system complexity increases
Solution Approach 1:
The mobile body is designed with multi-functionality by integrating both follow mode and position-ahead mode capabilities into a single system. This universal design allows one mobile body to serve multiple purposes (real-time following and advance positioning) without requiring separate specialized systems, thereby managing complexity while maintaining versatility.
4Ease of operation
If the mobile body follows the user in crowded areas, then the movement guidance is improved, but the safety risk increases
Solution Approach 1:
The mobile body performs preliminary positioning at a designated point before the user in crowded areas. This advance positioning allows the mobile body to be ready and wait safely at a predetermined location, reducing the risk of collision in crowded environments while still providing movement guidance when the user arrives.

AI summary
A mobile body control device acquires sensor information for recognizing an object around a mobile body, the sensor information including a captured image, sets one of a plurality of control modes, and controls traveling of the mobile body based on the set control mode and a result of detection of a specific person based on the sensor information. In a case where a first mode is set, the device controls the traveling of the mobile body in such a way that the mobile body travels together with the specific person when the person is walking. In a case where a second mode is set, the device controls the traveling of the mobile body in such a way that the mobile body moves to a point designated by the specific person before starting the first mode.
