DoorDash has unveiled a six-propeller aircraft for DoorDash Air, its planned commercial drone delivery service, after first developing the ground infrastructure and software needed to coordinate deliveries. DoorDash Labs, the research and development team behind the autonomous sidewalk delivery bot Dot, built the service and its Autonomous Delivery Platform (ADP), software that coordinates orders handled by people, sidewalk bots and drones. ADP uses smart routing, weighing factors including weather, flight range and ground traffic to determine which orders are suitable for air delivery. DoorDash says it designed the system around 13 years of merchant and customer order data, including typical package weights and delivery distances. The company has previously disclosed that more than 500,000 restaurants use its delivery marketplace. DoorDash announced the drone business in July after receiving Part 135 air carrier certification from the U.S. Federal Aviation Administration, allowing it to operate a commercial drone delivery service in the United States. The aircraft has six slow-spinning propellers mounted at the ends of its arms and a winch for collecting, carrying and lowering packages. Early pilot deliveries are planned in Northern California with Chipotle, Popeyes Louisiana Kitchen and Momo N Curry.
