Ohio Based Truck maker Workhorse has developed their own delivery drone that rides along on top of the truck and can deliver packages. So, if a driver had four deliveries in one part of town but only one in another, the drone might be able to handle that single, less convenient delivery. An operator will guide the drone on landing. Making sure to avoid people and obstacles, and releases the package. The drone then resumes autonomous flight and makes its way back to the truck.
