In February 2014, the Prime Minister and Minister of Cabinet Affairs of the United Arab Emirates (UAE) announced that the UAE planned to launch a fleet of UAVs for civilian purposes. Plans were for the UAVs to use fingerprint and eye recognition systems to deliver official documents such as passports, identification cards and licenses, and provide emergency services in accidents. A prototype battery-powered four-rotor UAV, approximately half a meter in diameter, was displayed in Dubai.

In the United States, initial attempts at commercial use of UAVs were blocked by FAA regulations, but were later allowed. In June 2014, the FAA published a document listing activities not permitted under its regulations, including commercial use, which the organization claimed included "delivering packages to individuals for a fee" or offered as part of a "purchase or other offer." The agency issued waivers to many organizations for less restrictive business uses, but each had to apply individually. In August 2016, the FAA adopted Part 107 rules allowing limited commercial use in its own right. Drone operation under these rules is restricted to the pilot's line of sight and is not permitted over people, meaning many applications such as delivery to populated areas still require an exemption. They also require that UAVs weigh less than 55 pounds (25 kg), fly up to a maximum of 400 feet (120 m), at a speed of no more than 100 miles per hour (160 km/h), only be operated during the day, and that drone operators must also qualify for flight certificates and be at least 16 years of age. In 2019, the FAA began certifying drone delivery companies under conventional Part 135 charter airline rules, with some adaptations for drones (such as the pilot's manual not needing to be on board). In preparation for higher volumes of drone traffic, the FAA finalized the Remote Identification regulation in December 2020, giving manufacturers 18 months and operators 30 months to comply with the requirement for self-identification transmissions outside of designated areas. At the same time, the FAA added a Night and People Operations rule to Part 107. Night operations require anti-collision lights and additional training for pilots. For flights over people or moving vehicles, drones are classified into four categories depending on the ability to cause injury to people, with the least restricted category being those that have a full Part 21 airworthiness certificate.

The concept of drone delivery entered the public realm with Amazon Prime Air, Amazon.com founder Jeff Bezos' December 2013 announcement that Amazon was planning rapid delivery of light commercial products using UAVs. Amazon's press release was met with skepticism, with perceived obstacles including federal and state regulatory approval, public safety, reliability, individual privacy, operator training and certification, security (hacking), cargo theft, and logistical challenges.

In December 2013, in a research project by Deutsche Post AG subsidiary DHL, a quantity of medicines weighing less than one kilogram was delivered via a prototype of Microdrones' "Parcelcopter", sparking speculation that disaster relief could be the first industry to use the technology.

In August 2014, Google revealed that it had been testing UAVs in Australia for two years. The Google X program known as "Project Wing" announced the goal of producing drones that can deliver products sold through e-commerce.

In February 2015, Hangzhou-based e-commerce provider Ali Baba started drone delivery service in partnership with Shanghai YTO Express, in which it delivered tea to 450 customers in selected cities in China.

In 2015, an Israeli startup, Flytrex, partnered with AHA, Iceland's largest e-commerce website, and together they started a drone delivery route that was proven to reduce delivery time from 30 minutes to less than 5 minutes.

In March 2016, Flirtey conducted the first FAA-approved fully autonomous drone delivery in an urban environment in the United States.

A partnership between 7-Eleven and Flirtey resulted in the first FAA-approved delivery to a residence in the United States in July 2016, delivering a frozen Slurpee. The following month, the company partnered with Domino's in New Zealand to launch the first commercial drone delivery service.

In China, JD.com has been developing drone delivery capabilities. As of June 2017, JD.com had seven different types of delivery drones in testing in four provinces in China (Beijing, Sichuan, Shaanxi and Jiangsu). The drones are capable of delivering packages weighing between 5 and 30 kg (11 to 66 pounds) while flying at speeds of up to 100 km/h (62 mph). The drones fly along fixed routes from warehouses to special landing pads where one of JD.com's 300,000 local contractors delivers packages to customers' doors in rural towns. The e-commerce giant is also working on a 1 metric ton (1,000 kg) delivery drone that will be tested in Shaanxi.

In January 2018, Boeing unveiled a prototype of a cargo drone for payloads up to 500 pounds (227 kg), an electric flight test platform that completed flight testing at Boeing's research and technology center in Missouri.

Zipline is the world's largest drone delivery network, delivering medical supplies to hospitals via automated drones. Zipline drones are made up of three main components: a foam chassis, wings, and a battery unit. They have two engines to keep the drone flying with a cargo compartment to hold the goods, until they are parachuted to the delivery site.

In 2016, Zipline began its partnership with the government of Rwanda to build and operate a medical distribution center in Muhanga. Rwanda has a mountainous geography, poor road conditions, and a long rainy season, making an air delivery system more cost-efficient and timely than traditional road-based deliveries. As of May 2018, they had delivered more than 7,000 units of blood using drones. By October 2020, Zipline had made more than 70,000 medical deliveries by drone and had expanded operations in Rwanda and Ghana.

Wing, a company incubated by Google As of April 2020, shippers were limited to FedEx, Walgreens, Sugar Magnolia, Mockingbird Café, and Brugh Coffee. Wing had obtained a Part 135 air carrier certificate from the FAA in April 2019, which allowed it to charge for carrying third-party cargo and operate outside the pilot's line of sight.

DHL, a pioneer in drone delivery, partnered with UAV manufacturer Microdrones in December 2013. This pilot program took place in the city of Bonn and delivered pharmaceutical products to employees at DHL's headquarters in Germany. This project led to DHL's Parcelcopter, which was tested in 2014 with a pilot project between the North Sea island of Juist and the mainland. The Parcelcopter could transport up to 1.2 kg of medicines across the sea over a distance of about 12 km in 15 to 25 minutes. This demonstrated to DHL that drone delivery was feasible, but the company ceased operations of the Parcelcopter in August 2021.

UPS, as of May 2020, has made more than 3,700 drone deliveries under Part 107 rules to WakeMed Hospital in Raleigh, North Carolina. In May 2020, UPS began receiving prescriptions via the Matternet M2 drone under Part 107 rules, approximately half a mile from a CVS to a central location in The Villages, Florida, from where a UPS employee makes home delivery by golf cart. In 2020, UPS also began drone deliveries between Wake Forest Baptist Medical Center's central campus in Winston-Salem and the health system's other locations. Another delivery service started for UC San Diego Health.

Amazon Prime Air first announced its intentions to launch a drone delivery service in 2013 with the announcement of its "octocopter" prototype. Deliveries are made within 30 minutes without human operation, using drones that carry loads of five pounds or less. Amazon currently offers this service in two locations in the United States, including College Station, Texas, and Lockeford, California. Prime Air safely delivers Amazon packages within these areas to customers in less than an hour.

Manna, founded in 2019, operates a fleet of delivery drones in Ireland. Manna was the first company in Europe to receive a European license to operate commercial drone deliveries. Your drone carries 3.5 kg with ~30,000 cm³. With commercial partnerships with Tesco, Unilever, Coca-Cola, Samsung and local pharmacy, takeaway, coffee, cake, book and hardware sellers, Manna has completed more than 100,000 delivery flights by March 2022.

Swoop Aero has been operating commercially for over 4 years and, to this point, has developed a network that delivers health supplies to some of the most inaccessible locations, such as the Nsanje and Chikwawa districts in southern Malawi, helping over 650,000 people. In total, the company serves more than 4.5 million people on 6 continents, with hopes of reaching 1 billion by 2030. During the COVID-19 pandemic, they were recognized as the first company in the world to remotely pilot commercially used drones from another country.

Swoop's drones are capable of completing round trips of around 260 kilometers and can carry a maximum weight of 18 kg, which is equivalent to 10 test kits or up to 50 vials of blood. The drones have a wingspan of 2.4 meters (nearly 8 feet) and must fly below 122 meters (about 400 feet) to ensure they do not collide with manned aircraft.

Drone technology continues to advance thanks to the various scientific research efforts being carried out. The global commercial drone market was valued at around $8 billion in 2022 and is projected to reach $47 billion by 2030. Improvements in drones include advances in autonomous flight, composite materials, next-generation batteries, extended flight times, and payload capabilities. As technology advances further, drones will be integrated with artificial intelligence and machine learning. The future of drone delivery is promising in different drone delivery applications.

Drug cartels have used UAVs to transport contraband, sometimes using GPS-guided UAVs.

Between 2013 and 2015, UAVs were observed delivering items to prisons on at least four occasions in the United States, while four similar but separate incidents occurred in Ireland, Great Britain, Australia and Canada. Although it is not a popular way to smuggle items into prisons, correctional officials say some people are beginning to experiment with UAVs.

In November 2013, four people in Morgan, Georgia, were arrested for allegedly attempting to smuggle contraband into Calhoun State Prison with a hexacopter.

In June 2014, a quadcopter crashed in the exercise yard of Wheatfield Prison, Dublin. The quadcopter collided with cables designed to prevent helicopters from landing to assist in escapes, causing it to crash. A package containing drugs was hanging from the quadcopter and was seized by prisoners before prison staff could reach it.

Between 2014 and 2015, at two South Carolina prisons, items such as drugs and cell phones were flown into the area with UAVs without authorities and one prison knowing how many deliveries were being successfully made to the facility before they came to the attention of authorities.

In the United States, the first attempts at the commercial use of unmanned aerial vehicles for food delivery, such as those made by the company Tacocopter, were blocked by the regulations of the Federal Aviation Administration. [7] Since 2014, the delivery of packages with unmanned aerial vehicles is not permitted in the United States.

In November 2013, four people were arrested in Morgan, Georgia, four people allegedly attempting to smuggle contraband into Calhoun State Prison with a six-rotor remote-controlled helicopter.[11][12] The suspects were found with “probably a pound or two of rolled tobacco.”[11][12]​

In 2014, a quadcopter crashed in a recreation yard at Wheatfield Prison in Dublin.[13]​[14][15]​ It collided with cables designed to prevent the landing of helicopters attempting to facilitate escapes, causing it to crash.[13]​[14]​[15]​ A package containing drugs hanging from the quadcopter was collected by prisoners before prison staff prison could do so.[13]​[14]​[15]​ The damaged quadcopter was handed over to the Garda Síochána.[13]​[14]​[15]​.

Between 2014 and 2015, some items such as drugs and cell phones were brought into the area of ​​two South Carolina prisons by unmanned aerial vehicles without authorities knowing how many were successfully carried out before they paid attention.[10]​.

Aircraft configuration

The design configuration of a delivery drone is usually defined by the use case of what is to be delivered and where it needs to be delivered.

A common configuration is a multirotor, such as a quadcopter or octocopter, which is a drone with horizontally aligned propellers. Another common configuration is a fixed wing design. A multirotor design provides power to lift the drone and payload, redundancy for powertrain failures, and the ability to hover and descend vertically (VTOL). However, a multirotor setup is less efficient and produces more noise. A fixed-wing configuration provides an order of magnitude increase in range, flight at higher air speeds and produces less noise, but requires more space for takeoff, handoff and landing.

There are also hybrid approaches (e.g. Wingcopter or Swoop Aero) that use multiple horizontal rotors for takeoff and landing, and vertical rotors combined with a fixed wing for forward flight.

Autopilot

There are many sensors on the drone that are necessary for it to fly autonomously. Inertial sensors, such as an accelerometer, help the drone stay in flight by providing data that allows the autopilot to adjust the speeds of the motors (multirotor configuration) or the deflections of the control surfaces (fixed wing configuration) to steer the drone. Navigation sensors, such as a GPS or magnetic sensors, help the drone fly along a specific path or toward a specific landmark by measuring the drone's location and orientation relative to the ground. Airflow sensors allow the drone to measure air speed, temperature and density, and that information maintains safe control of the aircraft. The drone can also use these sensors to estimate wind speed and direction to assist with package delivery or landing maneuvers.

In addition to these sensors, modern drones often incorporate a variety of additional cutting-edge technologies to improve their effectiveness in the air. Vision-based sensors needed for obstacle avoidance, terrain following, and taking high-resolution photos for mapping and surveillance include cameras and LiDAR (Light Detection and Ranging). Drones can fly safely through confined spaces thanks to these sensors, which process massive volumes of data to create real-time three-dimensional maps of the environment.

Communication systems also play a crucial role in the operation of autonomous drones. These systems allow the drone to communicate with a controller, other drones, or a central server for coordination and control. This is essential for applications such as fleet management in delivery services or precision agriculture, where multiple drones operate simultaneously. By integrating these different systems, drones are capable of performing a wide range of tasks autonomously, from simple aerial photography to complex, coordinated missions involving multiple aircraft. This fusion of sensors, along with advanced algorithms for processing and decision-making, allows drones to operate with high efficiency and precision in a variety of conditions and applications.

power train

Delivery drones need powerful motors to keep both the drone and cargo stable. Brushless DC motors are most commonly used in drones because they have become economical, lightweight, powerful, and small. The drone's propeller blades rotate at very high speeds, so the optimal material used for these rotor blades maximizes the strength-to-weight ratio. Some are made of carbon fiber reinforcing composites, while others are made of thermoplastics because they are cheaper, so the replacement cost when the drone crashes is lower. Lithium-ion batteries are used in most drones because they offer enough energy and power, and are relatively light so as not to weigh down the drone too much.

Ground control system

Delivery drones rely heavily on ground control systems to both ensure safe operations and support their business operations. This UAV operator allows communication and control over the drone and its payloads. This can be completed by setting parameters for autonomous operations or allowing direct control of the UAV. In terms of safety, the drone operator needs to manage their fleet of aircraft and how they fit into the wider airspace. For commercial use cases, ground systems allow receiving and tracking orders.

Parachute recovery systems

For regulatory compliance in many countries, drone delivery companies integrate parachute recovery systems. Parachute recovery systems can be unguided and guided. Drone delivery companies that incorporate this technology allow them to fly in more complex operations, such as over people. Drone delivery companies will purchase the integration service and parachute recovery systems from specific manufacturers.
