UPS wants to turn its delivery trucks into motherships for autonomous drones

For the past century, UPS has been hard at work refining the art of package delivery. After all, efficiency is the name of the game for the world's largest package carrier.

On Monday, UPS unveiled its latest innovation in package delivery technology.

In a test conducted near Tampa, Florida, UPS showed off a new hybrid-electric package truck with a drone nest built into its roof. In effect, UPS wants to turn their delivery trucks into drone motherships.

Inside the nest is a Workhorse HorseFly autonomous drone with the ability to fly for 30 minutes and carry 10 pounds worth of packages.

"This is really a vision for the future for us," UPS senior vice president for engineering and sustainability, Mark Wallace, said in an interview with Business Insider.

The drone will work as a mechanized helper for the driver, reducing the number of miles a driver will need to drive. According to Wallace, UPS can save $50 million a year if everyone of its drivers reduces the length of their delivery routes by one mile.

UPS sees several potential usage cases for its autonomous drones. This ranges from inventory control at warehouses to the delivery of urgent packages such as medical supplies. However, this latest test is geared towards the company's operations in rural areas where drivers have to cover vast distances between delivery points.

Currently, the technology still in the testing phase and UPS doesn't have an exact timeline for its introduction into service, Wallace said.

Here's a closer look at how UPS's truck-mounted drone works.
