SHERIDAN, WYOMING – Feb. 19, 2025 – Aurrigo International has unveiled a significant software update designed to bolster the performance of its autonomous vehicles in challenging weather conditions, specifically heavy rain and snow. This advancement addresses a critical hurdle for airports seeking to implement autonomous solutions for baggage and cargo handling. The new rainfall algorithm enables the vehicles to distinguish between raindrops and other objects, maintaining operational capability even in precipitation rates of up to 50mm per hour.
Overcoming the Challenges of Wet Weather
“Traditionally, very heavy rain has presented a significant problem for autonomous vehicles, particularly for lidar detection and navigation,” explained Simon Brewerton, chief technical officer at Aurrigo International. “Using this technology rely on the reflection feedback of laser beams for localization and object recognition and, in intense weather, the scattering and absorption of laser beams by raindrops can lead to distorted signals, compromising the vehicle’s ability to accurately perceive its surroundings.”
The software update, coupled with new protective housing for the lidar sensors, empowers Aurrigo’s Auto-DollyTug to transport baggage and cargo efficiently and safely, even in weather conditions that would typically disrupt manual operations. The software has undergone rigorous testing, including both simulated and real-world heavy rainfall, validated by both observation and rain meter readings.
Key Features of the Enhanced Software
The new software incorporates two key innovations. First, the rain filtering process is divided into five spatial zones surrounding the vehicle. This zonal approach allows for more precise identification and filtering of raindrops, minimizing interference with the lidar system. Second, the software addresses the challenge of detecting low-lying obstacles and reflective surfaces, which can be obscured by the filtering process. This has been achieved by adjusting field height settings and incorporating “near field” low profiles.
Real-World Testing and Airport Integration
Sam Layton, regional VP Singapore at Aurrigo International, discussed the rigorous testing conducted at a leading international airport. “The tests we did at a leading international airport had to prove the Auto-DollyTug could operate autonomously with no ghost or intermittent stops, react to a box and person injected into the vehicle’s path and safely navigate a T-junction airside with oncoming traffic left and right.” These tests demonstrated the Auto-DollyTug’s ability to navigate complex airport environments safely and reliably, even in adverse weather.
The Future of Airport Automation
Aurrigo’s advancements are crucial for the future of airport automation. “Automated equipment will be needed for baggage and cargo servicing, catering, water and refuelling. Our vehicles – Auto-DollyTug and Auto-Cargo – unlock the ULD and cargo pallet servicing pieces of that puzzle respectively. Our enhancement, together with other advanced systems, mean flight schedules will be maintained while reducing risk of injury to airside workers, two key priorities for airlines, and airport and ground support operators,” Layton added.
Benefits for Airlines and Airports
The improved all-weather capability of Aurrigo’s autonomous vehicles offers significant benefits to airlines and airports. By ensuring consistent operation regardless of weather conditions, these vehicles contribute to maintaining flight schedules and minimizing delays. Furthermore, they enhance safety by reducing the risk of injuries to airside workers, particularly in hazardous weather. The Auto-DollyTug and Auto-Cargo represent a significant step towards a more efficient and safer future for airport operations. This technology promises to streamline baggage and cargo handling, ultimately leading to improved passenger experiences and operational efficiency for airlines and airports worldwide. Aurrigo International's commitment to innovation and its focus on addressing real-world challenges position the company as a leader in the development of autonomous solutions for the aviation industry. The company continues to refine its technology and collaborate with airports to implement these solutions effectively.
