The small pilotless helicopter flew a package of medicine Monday from a pharmacy in the town of Bonn to the company's headquarters on the other side of the Rhine River. The aircraft can carry up to 3 kilograms (6.6 pounds).
Company spokesman Thomas Kutsch says the flights all this week are strictly a research project to see if the technology works and there are no plans yet to start actual drone deliveries. The test flights required permission from local aviation authorities.
On-line retailer Amazon is also working on a drone to deliver goods to customers despite legal obstacles in the U.S.
