Aerial Drone Trail Reconnaissance for Off-Road Route Decisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles face challenges in traversing off-road trails due to varying conditions, such as debris and weather, leading to frustrating and potentially dangerous situations where they need to reverse or turn around.
Innovation Solution
An aerial drone equipped with image capture capabilities navigates ahead of the vehicle, analyzing trail conditions to determine if they are traversable (positive) or not (abandonment), generating sparse maps that highlight these conditions, and guiding the vehicle accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle operates on off-road trails with varying conditions, then the vehicle can access diverse terrain and explore different routes, but the vehicle may encounter untraversable sections requiring reverse operation or turning around, reducing operational efficiency and safety
Solution Approach 1:
The aerial drone performs preliminary reconnaissance of off-road trails ahead of the vehicle, capturing images and analyzing conditions before the vehicle reaches problematic sections. This advance information allows the vehicle operator to plan routes proactively, avoiding untraversable sections entirely rather than discovering them too late and having to reverse or turn around.
Solution Approach 2:
The aerial drone acts as an intermediary between the vehicle operator and the complex off-road environment. It captures images of trail conditions, processes them to identify traversable versus untraversable sections, and presents simplified route guidance to the operator. This intermediary system bridges the gap between the vehicle's limited direct observation capabilities and the complex, varying off-road conditions ahead.
2Speed
If the vehicle operator directly navigates off-road trails without advance information, then the operator can respond quickly to immediate conditions, but the operator cannot anticipate obstacles or plan optimal routes, leading to inefficient operations
Solution Approach 1:
The system performs preliminary action by having the aerial drone capture and analyze trail condition images before the vehicle reaches those sections. This advance information gathering and processing provides the operator with knowledge of upcoming obstacles, terrain difficulties, and safe passage points, enabling better route planning without slowing down vehicle traversal.
Solution Approach 2:
The system establishes a feedback loop where the aerial drone continuously monitors trail conditions ahead and relays information back to the vehicle operator in real-time or near real-time. This feedback mechanism allows the operator to adjust the vehicle's course and speed based on current trail conditions while maintaining forward momentum, avoiding the need to slow down for reconnaissance.
3Reliability
If the vehicle encounters untraversable sections requiring reverse operation, then the vehicle can eventually continue its journey, but the reverse operation creates dangerous situations and frustrates the occupant
Solution Approach 1:
The aerial drone performs preliminary reconnaissance to identify untraversable sections before the vehicle reaches them. By providing advance warning of obstacles such as fallen trees, rocks, or difficult terrain, the system allows the operator to plan alternative routes or prepare appropriate应对措施, avoiding the need for reverse operation entirely and maintaining continuous forward progress.
Solution Approach 2:
The system applies preliminary anti-action by preemptively identifying and avoiding untraversable sections before the vehicle encounters them. The aerial drone's advance detection and the operator's proactive route planning create a countermeasure that prevents the harmful situation of reverse operation from occurring in the first place, rather than merely responding to problems after they arise.
Data Source
AI summary
A system includes a processor and a memory in communication with the processor. The memory includes instructions that cause the processor to determine, based on images of an off-road trail captured by an aerial drone in communication with a vehicle, whether the off-road trail has a positive condition indicating that the vehicle can traverse the off-road trail or an abandonment condition indicating that the vehicle cannot traverse the off-road trail. Depending on the determination, the processor either controls the aerial drone to navigate along the off-road trail or controls the aerial drone to navigate to a different off-road trail.
