When it comes to making deliveries efficient and environmentally friendly, faster seems to be better. The less time a drone spends in the air is a primary determinant of its energy consumption according to Carnegie Melon University Professor Costa Samaras. A 2018 study coauthored by him discovered that, over certain distances, drone delivery is more efficient than ground-based delivery, especially if drones are traveling at higher speeds.
Still, the environmental concerns loom. A company like Amazon might create drone delivery facilities to make good on faster guaranteed delivery times, but that would also mean more facilities to operate and maintain, and more of an environmental impact.
Indeed, the promise of drone delivery means everyone can order everything and have it arrive almost instantly. But in urban environments, people ordering a cup of coffee or breakfast bagel first thing in the morning might not be a feasible option, and could lead to increased pollution. It also means that providers would need more space dedicated to shipping and maintaining drones, which means more warehouses. You could have a single warehouse and fly drones until their batteries die, says Samaras, but that defeats the efficient nature of drone usage. For more efficient flights, companies will need multiple warehouses storing identical products to deliver to neighborhoods.
Currently, Samaras says drones for delivery use in rural areas paired with delivery trucks are an ideal application of the technology, considering the environmental cost of driving something like a multi-ton delivery truck to every house in a rural community. Drones are already being used by hospitals in far-flung regions to deliver medical supplies like blood, and by the U.S. Army to move military equipment like ammunition.
Decentralized drone delivery could also lead to less congestion, according to University of Texas operations management professor Milind Dawande, which is more obvious vital now than ever as the global supply chain stalls in shipping bottlenecks at ports. But Dawande coauthored a study last year that showed how using drones to decrease delivery times could lead to an increase in demand.
The logistics industry is abuzz with all things drones. But not all drone systems are equal. Some feature remotely piloted drones. Other drones are autonomous but blind, relying on ground-based communications systems for situational awareness, not able to react to the unexpected.
Our team has logged thousands of flight hours and put our drones through rigorous testing and evaluation. We safely test the limits of our drones in this controlled area in accordance with regulatory requirements to make sure the vehicle we use for delivery is a safe one.
Nearly a decade of building, testing, and iterating has taught us valuable lessons. In fact, just through the last two years of testing, we have made over 188 updates to our system that have improved aspects like noise and equipment ergonomics.
Amazon received federal approval to operate its fleet of Prime Air delivery drones, the Federal Aviation Administration said Monday, a milestone that allows the company to expand unmanned package delivery.
Amazon said it will use the FAA's certification to begin testing customer deliveries. The company said it went through rigorous training and submitted detailed evidence that its drone delivery operations are safe, including demonstrating the technology for FAA inspectors.
"This certification is an important step forward for Prime Air and indicates the FAA's confidence in Amazon's operating and safety procedures for an autonomous drone delivery service that will one day deliver packages to our customers around the world," David Carbon, vice president of Prime Air, said in a statement. "We will continue to develop and refine our technology to fully integrate delivery drones into the airspace, and work closely with the FAA and other regulators around the world to realize our vision of 30 minute delivery."
The company has zeroed in on drone delivery as part of a push to get packages quicker to Prime members. Since last year, Amazon has also invested billions of dollars to transition from two to one-day delivery.
Amazon began testing delivery drones in 2013, aiming to drop off packages at customers' doorsteps in 30 minutes or less. In August 2019, the company submitted a petition for FAA approval of those plans. In its petition, Amazon said deliveries would occur in areas with low population density and packages would weigh 5 pounds or less.
The company debuted a new, electric delivery drone at its 2019 re:MARS conference that's capable of carrying packages under 5 pounds to customers within a half-hour and can fly up to 15 miles. Jeff Wilke, Amazon's CEO of worldwide consumer, said at the time that the drone could be used by the company "within months" to deliver packages.
Amazon isn't the only company seeking to expand commercial drone delivery. Last April, Alphabet-owned Wing became the first drone delivery company to receive FAA approval for commercial deliveries in the U.S. UPS last October won approval from the FAA to operate a fleet of drones as an airline.
"If the drone encounters another aircraft when it's flying, it'll fly around that other aircraft. If, when it gets to its delivery location, your dog runs underneath the drone, we won't deliver the package," said Calsee Hendrickson, who leads product and program management for the Prime Air drone program.
The box is loaded into the back and secured inside, then the drone takes off vertically, similar to a helicopter, using six propellers. Once in the air, it rotates into a forward position and the hexagon surrounding the drone serves as its wings. Hendrickson said it flies at about 50mph. Once at the delivery location, it descends vertically, scans the area to make sure it's clear, then drops the box from a hover 12 feet above the ground.
As it prepares to bring free Prime Air drone deliveries to customers in California and Texas, Amazon is offering an inside look at how its drone delivery system works. A new video released by the company shows rigorous flight tests being conducted at one of its facilities in Oregon.
In this scheme of things, a sense-and-avoid system, aka the brain of this aircraft, will play a major role in ensuring that the delivery drone is able to detect and stay away from obstacles both in the air and on the ground. This system would also allow the drone to make on-the-spot decisions, autonomously and safely, if it encounters an unexpected situation.
Amazon further explains that it is creating an automated drone-management system to plan the flight paths and ensure there are safe distances between its drone and other aircraft, while complying with all aviation regulations.
Our team has logged thousands of flight hours and put our drones through rigorous testing and evaluation. We safely test the limits of our drones in [a] controlled area in accordance with regulatory requirements to make sure the vehicle we use for delivery is a safe one.
The goal of the new delivery system is to get packages into customers' hands in 30 minutes or less, the world's largest Internet retailer said. Putting Prime Air into commercial use will take "some number of years" as Amazon develops the technology further and waits for the Federal Aviation Administration to come up with rules and regulations, the company added.
If drone delivery takes off, it could be a threat to FedEx and UPS, which Amazon uses for a lot of its deliveries now. Indeed, FedEx founder Fred Smith told Wired magazine in 2009 that the company wanted to switch their fleet to drones as soon as possible but that it had to wait for the FAA to regulate such activity.
Amazon this year aims to recruit 1,300 test customers to place orders through its Prime Air drone-delivery program, a sign the company is inching closer to its vision of shipping packages via autonomous aerial vehicles, Insider has learned.
The expansion of its testing program would mark the largest public-facing step forward for Prime Air, nearly 10 years after Amazon's founder Jeff Bezos unveiled the vision for drone-delivery service in a "60 Minutes" segment. Amazon's goals for the program are ambitious, with plans to ultimately operate 145 drone launchpads, have 250 drones in the air at any one time, and deliver 500 million packages by drone a year, the documents say.
Amazon needs those test flights for regulatory approval. One of the documents said Prime Air has to obtain the Federal Aviation Administration's type certificate for its latest drone model, an approval of the aircraft's design and safety. It said that the customer-initiated test flights would "demonstrate system maturity and service expansion readiness" and that the application for the type certificate would be "submitted upon completion" of the durability and reliability testing.
Amazon has largely been silent about Prime Air's progress lately. Its last major milestone was in August 2020, when Amazon won the FAA's approval to use "unmanned aircraft systems" in a commercial operation. It's been a noticeably slow process with several missed goalposts. In 2013, Bezos predicted Amazon would be delivering packages by drone within "four or five years." Jeff Wilke, Amazon's former retail CEO, announced in June 2019 that Prime Air would launch "within months."
