Wearable AR Guidance for UGV Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned ground vehicles (UGVs) frequently interfere with unspecified people on public or private roads, parks, or inside buildings, leading to frequent stops and compromised delivery efficiency in automated delivery services.
Innovation Solution
An interference controller apparatus and method that uses a controller server to generate and transmit signals to wearable AR glasses, displaying the UGV's path and danger zones, enabling users to avoid collisions without interrupting the UGV's travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UGVs are stopped each time to avoid collisions with people on roads, then collision safety is improved, but delivery productivity deteriorates due to frequent stops
Solution Approach 1:
Instead of stopping the UGV to avoid collisions, the invention inverts the approach by providing warning information to pedestrians through wearable devices. This allows the UGV to maintain its travel schedule while pedestrians are alerted to avoid the vehicle's path, thus resolving the contradiction between safety and productivity.
Solution Approach 2:
The invention introduces wearable devices as an intermediary between the UGV and pedestrians. The controller server communicates collision risk information to pedestrians via their wearable devices, enabling them to take evasive action without requiring the UGV to stop. This mediator approach maintains both safety and delivery efficiency.
2Productivity
If UGVs travel automatically on public roads without interruption, then delivery productivity is improved, but collision risk with unspecified people increases
Solution Approach 1:
The system performs preliminary action by notifying pedestrians of the approaching UGV before the vehicle reaches them. The controller server determines collision risk in advance and transmits warning information to wearable devices, allowing pedestrians to take preventive action and avoid collisions without interrupting the UGV's automated delivery route.
Solution Approach 2:
The invention implements feedback by continuously monitoring the positions of both the UGV and pedestrians, calculating collision risk, and providing real-time warning information to pedestrians. This feedback loop enables the UGV to travel automatically while maintaining safety through informed pedestrian behavior.

AI summary
An interference controller apparatus performs a process for acquiring a first position at which an unmanned ground vehicle is positioned and a second position at which a wearable device worn by a user is positioned, respectively; a process for acquiring route information indicating a route on which the unmanned ground vehicle is to travel; a process for generating a first signal for displaying a first image indicating a direction and a path that the unmanned ground vehicle is to travel based on the first position and the route information; a process for generating a second signal for displaying a second image indicating a zone where an entry of a user wearing the wearable device is to be restricted, based on the first position, the second position, and the route information; and a process for transmitting the first signal and the second signal to the wearable device.
