Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile body control technologies for robots and self-propelled vehicles in environments like airports and amusement facilities lack advanced features for assisting user movement with improved usability and safety, particularly in crowded areas and varying terrain.
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, adjusting speed, trajectory, and positional relationships to provide leading, follow, guide, and delivery modes, enhancing user assistance and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile body travels in crowded areas to assist user movement, then usability and user assistance are improved, but collision risk and safety hazards increase
Solution Approach 1:
The mobile body dynamically adjusts its traveling speed based on detected crowd density and user movement patterns. The control unit modifies speed parameters in real-time to maintain safe distances while continuing to assist user movement, resolving the contradiction between providing assistance and avoiding collisions.
Solution Approach 2:
The system continuously monitors sensor information about surrounding objects and user position, feeding this data back to the control unit. Based on this feedback, the control unit adjusts traveling parameters to prevent collisions while maintaining assistance functionality, thereby resolving the safety-usability contradiction.
2Reliability
If the mobile body adjusts traveling speed and trajectory frequently to navigate crowded areas, then collision avoidance and safety are improved, but control complexity and energy consumption increase
Solution Approach 1:
The control unit adjusts key traveling parameters (speed, trajectory) based on detected environmental conditions and user needs. By systematically modifying these parameters in response to sensor feedback, the system achieves reliable collision avoidance while managing control complexity through parameter-based adaptation rather than complex structural changes.
3Device complexity
If the mobile body maintains a fixed positional relationship with the user, then control simplicity is improved, but adaptability to different user needs and environments deteriorates
Solution Approach 1:
The mobile body transitions from fixed positional relationships to dynamic positioning that adapts to different user needs and environmental conditions. The control unit continuously adjusts the positional relationship based on sensor information and detected user requirements, enabling versatile assistance while maintaining relatively simple control logic through dynamic adaptation.

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 obtained by capturing a periphery of the mobile body, and sets one of a plurality of control modes. The device 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. The device controls the traveling of the mobile body in such a way that the mobile body travels based on a traveling speed of the mobile body, generation of a traveling trajectory of the mobile body, and a positional relationship between the specific person and the mobile body for the control mode.
