Drone Delivering MailVIDEO: The Workhorse Group is on the short list of possible manufacturers to replace the USPS delivery fleet. Unlike competitors, though, it offers something more: a combo delivery vehicle-drone system. Working with the University of Cincinnati, the Workhorse Group developed a system whereby an electric delivery truck and drone work in tandem to deliver packages to houses. Called the “Horsefly”, the drone scans the barcode of the package, takes off from the delivery vehicle, and uses GPS technology to drop the package to the resident’s door. The Horsefly docks on the delivery vehicle — called the Workhorse — where it recharges its batteries. The Workhorse has a range of 50-100 miles per charge. See video.
