On a blueberry farm outside of Tampa, Florida, on Monday, UPS tested the use of drones for residential delivery for the first time.

The logistics juggernaut specifically launched an octocopter, or multi-rotor drone, from the top of a delivery van. The drone delivered a package directly to a home, then returned to the van which had now moved down the road to a new location. The van pulled the drone down with robotic arms, to dock on its roof.

The drone used in Monday’s test was made by Ohio-based Workhorse Group Inc., already a UPS technology supplier. Workhorse builds commercial, hybrid electric trucks, batteries and develops aerospace technologies as well. UPS has purchased 350 of its electric hybrid trucks, 125 of which are already on the road today. The company’s new HorseFly UAV Delivery system used in the UPS test was tailored to work with its vehicles.

The truck for the test was custom-built to be able to launch the HorseFly drone from its roof, then grab it upon its return with robotic arms. A cage suspended beneath the drone extends through a hatch in the truck, where the drone can be lowered down and loaded up with another package. While docked, the drone recharges through a physical connection between its arms and the truck’s electric battery.

The concept of delivery vans that launch drones is not new. Mercedes Benz and drone tech startup Matternet revealed plans to develop “Vision Vans,” which launch Matternet’s delivery drones from Mercedes-Benzs trucks, back in September of 2016. They unveiled a real world version of the delivery vans at CES, as well.

According to UPS Vice President of Engineering, John Dodero, the company’s goal is to have drones work off of any type of vehicle, whether gas-powered or electric, to make last-mile deliveries. “That nest that we have on top of the car would be able to be put on any car, but we have to make sure it has the capabilities and it’s set up to do the charging,” he explains.

As for the HorseFly itself, the 9.5-pound drone features a carbon fiber construction, is powered by a proprietary lithium 18650 battery pack, and capable of a 30-minute flight time at a top speed of 45 miles per hour, the company says. By contrast, most consumer drones will only fly for about 22 minutes. The HorseFly can carry a package up to 10 pounds, allowing UPS to handle a wide range of residential deliveries.
