The Parrot AR.Drone was unveiled at the International CES 2010 in Las Vegas along with a demonstration of the iOS applications used to control it. Along with AR.Freeflight, the application designed for the free operation of the drone, Parrot also released AR.Race, allowing users to take part in solo games, or interact with other drones in combat simulations.{{Cite news|title=The iPhone: Now There's a Helicopter for That|url=https://www.kualadeals.com/collections/rcs-drones|work=Associated Press in the New York Times|date=January 8, 2010|access-date=2010-01-11|archive-date=2018-04-25|archive-url=https://web.archive.org/web/20180425183612/https://www.kualadeals.com/collections/rcs-drones|url-status=dead}}

The airframe of the AR.Drone, constructed from nylon and carbon fiber parts, which make it light weight, measures {{convert|57|cm|in|abbr=on}} across.{{cite web | url=https://www.amazon.com/Parrot-AR-Drone-Quadricopter-Controlled-Android/dp/B003ZVSHB0 | title=Parrot AR.Drone Quadricopter Controlled by iPod touch, iPhone, iPad, and Android Devices (Orange/Blue) | publisher=Amazon | work=Amazon.com | access-date=2013-04-24}} Two interchangeable hulls were supplied with the airframe, one is designed for indoor and one for outdoor flight. The indoor hull is made from EPP foam, and encases the circumference of the blades for protection. The outdoor-use hull is made from lightweight plastic and allows for increased maneuverability. In total, the AR.Drone has six degrees of freedom, with a miniaturized inertial measurement unit tracking the pitch, roll, and yaw for use in stabilisation.{{Cite news|title=Parrot AR.Drones specs |url=http://diydrones.com/profiles/blogs/parrot-ardrones-specs-arm9|work=Chris Anderson from DIYDrones.com |date=January 6, 2010|access-date=2010-01-06 }}

Inside the airframe, a range of sensors assist flight, enabling the interface used by pilots to be simpler, and making advanced flight easier. The onboard computer runs a Linux operating system, and communicates with the pilot through a self-generated Wi-Fi hotspot. The onboard sensors include an ultrasonic altimeter, which is used to provide vertical stabilization up to {{convert|6|m|ftin|abbr=on}}. The rotors are powered by 15-watt, brushless motors powered by an 11.1 Volt lithium polymer battery. This provides approximately 12 minutes of flight time at a speed of {{convert|5|m/s|mph|abbr=on}}. Coupled with the software on the piloting device, the forward-facing camera allows the drone to build a 3D environment, track objects and drones, and validate shots in augmented reality games.

The successor to the original drone, the AR.Drone 2.0 was unveiled at CES Las Vegas 2012. Rather than redesigning the product, improvements were made to its functionality, along with developing a larger ecosystem to support pilots.

The equipment on board AR.Drone 2.0 was significantly upgraded to improve the drone's function. The camera quality was increased to 720p, and many of the onboard sensors were made more sensitive, allowing for greater control. The ultrasound altimeter was enhanced with the addition of an air pressure sensor, allowing for more stable flight and hovering. The resources available to the onboard computer were also improved, and the Wi-Fi hardware was updated to follow the new 802.11n standard. Other sensor improvements included an upgraded 3-axis gyroscope, along with a 3-axis accelerometer and magnetometer.{{cite web|title=Parrot AR.Drone|url=https://www.spacecitydrones.com/parrot-ar-drone/|publisher=Space City Drones|access-date=3 April 2016|archive-date=22 March 2016|archive-url=https://web.archive.org/web/20160322211857/https://www.spacecitydrones.com/parrot-ar-drone/|url-status=dead}}

At CES 2013, Parrot announced the Flight Recorder add-on for the AR.Drone 2.0. It adds 4GB of storage to the drone, along with GPS tracking and flight data recording. It will allow pilots to define a flight path by selecting a series of waypoints that the drone will follow. Flight Recorder features can be controlled via mobile phone and desktop applications, with "Director Mode" and "Rescue Mode" included. An extended battery designed to increase flight time by up to 50% was also launched alongside the Flight Recorder.{{cite web|last1=Heater|first1=Brian|title=Parrot announces availability for AR.Drone 2.0 add-ons, offers software upgrades|date=17 June 2013 |url=https://www.engadget.com/2013/06/17/parrot/|publisher=Engadget|access-date=3 April 2016}}

In France, the AR.Drone 2.0 was tested by a Special Operations unit for aerial reconnaissance,{{cite web | url=http://blog.parrot.com/2013/03/07/special-operations-unit/ | title=Special Operation Unit tests AR.Drone 2.0 | publisher=Parrot | work=Parrot Blog | date=2013-03-07 | access-date=2013-04-15}} whilst other companies have been developing software that allows the drone to track sports activities,{{cite web | url=http://www.huffingtonpost.com/2012/06/07/joggobot-drone-helicopter-jogging_n_1574329.html | title=Joggobot Is A Drone Helicopter Who Wants To Be Your Jogging Trainer | publisher=Huffington Post | date=2012-06-07 | access-date=2013-04-15 | author=Gilbert, Jason}} and generate training feedback.{{Cite book|url=http://dl.acm.org/citation.cfm?id=1959833|author1=Keita Higuchi, Tetsuro Shimada |author2=Jun Rekimoto |title=Proceedings of the 2nd Augmented Human International Conference |chapter=Flying sports assistant: External visual imagery representation for sports training |date=13 March 2011 |pages=1–4 |doi=10.1145/1959826.1959833 |isbn=9781450304269 |s2cid=3336372 |name-list-style=amp |access-date=5 November 2011}} An AR.Drone was used by Tim Pool during the Occupy Wall Street protest, running modified software that allowed it to stream directly to an internet channel. He theorised that a chain of command could be set up, where multiple people could step up and take control should the primary operator be detained by police. To further this, he began the development of a new control system, replacing the existing Wi-Fi hotspot with a 3G chip. This would allow users to control drones via the internet, and potentially from remote locations.{{cite web | url=https://www.theguardian.com/commentisfree/cifamerica/2011/dec/21/occupy-wall-street-occucopter-tim-pool | title=Occupy Wall Street's 'occucopter' - who's watching whom? | publisher=Guardian | date=2011-12-21 | access-date=2013-04-15 |author1=Sharkey, Noel |author2=Knuckey, Sarah |name-list-style=amp }}

Although the technology required to feed and record live video taken from unmanned aerial vehicles (UAVs) existed before the release of the AR.Drone was not widely available to members of the public. In Germany, consumer affairs minister Ilse Aigner described the drone as a privacy threat, and called for restrictions to be placed on the use of cameras mounted on aerial platforms.{{cite web | url=http://www.suasnews.com/2011/01/3268/parrot-ar-drone-causes-german-politicians-to-debate-privacy-and-suas/ | title=Parrot AR.Drone causes German politicians to debate privacy and sUAS | publisher=sUAS | date=2011-01-02 | access-date=2013-04-25 | author=Mortimer, Gary}} A UK advertising campaign, showing an AR.Drone being flown into the grounds of Buckingham Palace was withdrawn after concerns that it was demonstrating illegal use of the drone.{{cite web | url=http://www.suasnews.com/2010/09/1869/uk-caa-underline-legal-position-in-for-suas/ | title=UK CAA underline legal position for sUAS | publisher=sUAS News | date=2010-09-25 | access-date=2013-04-25 | author=Mortimer, Gary}} In the US, the use of AR.Drones are governed by the Federal Aviation Administration at the Federal level and local jurisdiction,{{cite web | url=http://www.quadcopteracademy.com/faa-drone-regulations/ | title=FAA Drone Regulations | publisher=Quadcopter Academy | date=2014-06-12}} which restricts the use of UAVs above 400 ft, and does not allow them to be used for commercial purposes.{{cite web | url=http://hackaday.com/2012/08/29/what-does-the-government-think-about-that-drone-in-your-home/ | title=What does the government think about that drone in your home? | publisher=Hack a Day | date=2012-08-29 | access-date=2013-04-25 | author=Kraft, Caleb}}{{update inline|date=April 2016}}

;AR.Drone

Previously known as AR.Freeflight, provides piloting function for AR.Drones, and the ability to take photos and videos. AR.Drone was launched in 2010 alongside the original drone, and provides piloting capabilities via iOS devices.{{cite web | url=https://itunes.apple.com/us/app/ar.drone/id628452459?mt=8 | archive-url=https://web.archive.org/web/20130504192110/https://itunes.apple.com/us/app/ar.drone/id628452459?mt=8 | url-status=dead | archive-date=May 4, 2013 | title=AR.Drone for iPhone, iPod touch and iPad | publisher=Apple | work=iTunes Preview | date=2013-04-20 | access-date=2013-04-25}} It allows pilots to record video or capture images from their drone's onboard cameras. When originally launched pilots could control drones by tilting their device, and data from the onboard accelerometer was converted into flight controls.{{cite web | url=http://blog.parrot.com/2013/04/08/statement-to-ar-drone-pilots-using-ios-devices/ | title=Statement to AR.Drone pilots using iOS devices | publisher=Parrot | work=Parrot Blog | date=2013-04-08 | access-date=2013-04-25}} On-screen controls provide joystick-style movement, and other functions that allow pilots to perform aerobatics, play games, or update their drone's firmware. The app also integrates with AR.Drone Academy, where pilots can map and share flight details with other AR.Drone users. AR.Drone is available on the Google Play store, where it has kept the name AR.Freeflight.{{cite web | url=https://play.google.com/store/apps/details?id=com.parrot.freeflight&hl=en | title=AR.Freeflight 2.0 | work=Android Apps on Google Play | date=2013-02-25| access-date=2013-04-25}}

;AR.Race 2 (previously AR.Race)

AR.Race is a piloting and multiplayer gaming application for the AR.Drone 2.0. Using a target included with the drone, pilots can define a race course with a start and finish line. The drone will then detect when it crosses this line and records the flight time in between these two events. Pilots may invite other AR.Drones to join the race, and scores are aggregated into a leaderboard.{{cite web | url=http://ardrone2.parrot.com/apps/ar-race/ | title=AR.Drone 2.0.

AR.Race 2, and its predecessor AR.Race is only available on iOS devices.

;AR.Rescue 2 (previously AR.Rescue)

A single-player augmented reality application for iOS devices. It uses the target provided with the AR.Drone 2.0 builds a 3D environment in which pilots must perform various tasks. The object of the game is to construct a rocket out of pieces that are placed into the physical environment by the drone's software. Along with these pieces, enemies are generated that must be fought. The drone also records the time it takes to complete this task successfully, and this is recorded in AR.Drone Academy, where a global leaderboard is generated, and videos and images can be shared amongst the community.{{cite web | url=https://itunes.apple.com/us/app/ar.rescue-2/id536571404 | archive-url=https://web.archive.org/web/20120723221957/http://itunes.apple.com/us/app/ar.rescue-2/id536571404 | url-status=dead | archive-date=July 23, 2012 | title=AR.Rescue 2 for iPhone, iPod touch, and iPad | publisher=Apple | work=iTunes Preview | date=2013-04-02 | access-date=2013-04-25}}

;AR.Hunter

An augmented, multiplayer game that allows pilots to engage a human target with virtual weapons within a 3D space. Unlike the other multiplayer games made by Parrot, AR.Hunter only requires one AR.Drone. Both the pilot and the 'target' have the application installed on iOS devices, and the 'target' uses theirs to fire their virtual weapons at the drone. For the drone to recognise and engage the 'target', they must wear a colored cap, purchased separately from Parrot. The game can be played without the cap, but the drone is unable to engage the 'target', and the pilot must instead evade detection or attack. AR.Hunter is not compatible with the AR.Drone 2.0.
