DJI


SZ DJI Technology Co., Ltd. or Shenzhen DJI Sciences and Technologies Ltd. in full, more popularly known as its trade name DJI which stands for Dà-Jiāng Innovations, is a Chinese technology company headquartered in Shenzhen, Guangdong with factories throughout the world. DJI is a world-leading manufacturer of commercial unmanned aerial vehicles for aerial photography and videography. It also designs and manufactures camera gimbals, action cameras, camera stabilizers, flight platforms and propulsion systems and flight control systems.
DJI is the dominant market leader in the civilian drone industry, accounting for over 70 percent of the world's drone market. Its camera drone technology has been used widely for the music, television and film industries. The company's products have also been used by militaries and police forces, as well as terrorist groups, with the company taking steps to limit access to the latter. US government institutions have issued statements discouraging their internal use of DJI products, but as of 2020, various agencies at the local and federal level continue to use DJI products.

History

The company was founded in 2006 by Frank Wang. Wang, who went to Hong Kong in 2003 after enrolling for a degree course in Hong Kong University of Science and Technology. He was part of the HKUST team participating in ABU Robocon and won third prize.
Wang built the first prototypes of DJI's projects in his dorm room, selling the flight control components to universities and Chinese electric companies. He used the proceeds to move to the industrial hub of Shenzhen and hired a small number of staff in 2006. The company struggled at first, with a high degree of churn among employees that has been attributed to Wang's abrasive personality and perfectionist expectations of his employees. The company sold a modest amount of components during this period, relying as well on financial support from Wang's family friend, Lu Di, who provided USD $90,000 and managed the company's finances. In 2009, DJI's components allowed a team to successfully pilot a drone around the peak of Mt. Everest.
In 2010, Wang hired a high school friend, Swift Xie Jia, to run the company's marketing. DJI began to cater more to drone hobbyists in markets outside of China. In 2011, Wang met Colin Guinn at a trade show, and the two of them founded DJI North America, a subsidiary company focusing on mass market drone sales. In 2013, DJI released the first model of the Phantom drone, an entry-level drone which was significantly more user-friendly than any other drone on the market at the time. The Phantom was a worldwide commercial success, but this success led to conflict between Guinn and Wang. Midway through the year, Wang made an offer to buy Guinn out, which Guinn refused. By the end of the year, DJI had locked all employees of the North American subsidiary out of their email accounts and was well on its way to shutting down the subsidiary's operations. Guinn sued DJI, and the case was settled out of court.
In 2015, DJI eclipsed the success of the Phantom with the release of the Phantom 3, whose even greater popularity was in part due to the addition of a built in live-streaming camera. DJI was now the largest consumer drone company in the world, driving many of its competitors out of the market over the following years. 2015 also marked the beginning of DJI's RoboMaster Robotics Competition, an annual international collegiate robot combat tournament held at the Shenzhen Bay Sports Centre.
In 2017, DJI won a Technology & Engineering Emmy Award for its camera drone technology, which was used in the filming of various television shows including The Amazing Race, American Ninja Warrior, Better Call Saul and Game of Thrones. That same year, Wang became Asia's youngest tech billionaire.
2017 was also the year that DJI announced a plan to provide surveillance drones for use by the Chinese police in Xinjiang. In August, the United States Army published internal guidance banning the use of DJI products for security reasons, although as of 2019 other branches of the US military continue to use its products in a limited capacity. On 17 November 2017, Ars Technica reported a security breach of private customer data at DJI. The company denied the existence of such a breach, and subsequently added an offline mode that allows its drones to fly without transferring data over the internet.
On 5 June 2018, police body cam and Taser maker Axon announced a partnership with DJI to sell surveillance drones to U.S. police departments. As of 2020, DJI products are also widely used by American police and fire departments.
On 21 January 2019, DJI announced that an internal probe had uncovered "extensive" fraud by certain employees who "inflated the costs of parts and materials for certain products for personal financial gain." DJI estimated the cost of the fraud at "up to RMB 1 billion", but maintained that the company "did not incur a full year loss in 2018."
In January 2020, the United States Department of the Interior announced that it would be grounding around 800 drones, which it had been using for wildlife conservation and infrastructure monitoring purposes. As of March 2020, DJI holds nearly 77% of the US market share for consumer drones, with no other company holding more than 4%.

Incidents involving DJI products

In January 2015, a Phantom 3 crashed into the White House's south lawn, in Washington, D.C., US. DJI later set up a no-fly Geo-system according to prohibited airspace, and forced all drones to update the firmware. The new system will forbid flights getting closer or take off in restricted zones based on its GPS location.
In 2016, ISIS used DJI drones as exploding devices in Iraq. DJI later created a broad no-fly zone over nearly all of Iraq and Syria. That year, a DJI drone was nearly involved in a midair collision with a Chinese fighter jet. The Chinese government subsequently insisted that DJI develop an air traffic registry to track its drones within China.
On 30 March 2018, Israel Defense Forces used DJI’s Matrice 600 drone to drop tear gas from above caused injuries, panic and death during Gaza and West Bank protests.
On 4 August 2018, two Matrice 600 drones detonated explosives near Avenida Bolívar, Caracas in an apparent attempt to assassinate Nicolás Maduro.

Company infrastructure

DJI is known for having a very difficult hiring process, as well as an extremely competitive internal culture. Teams are often pitted against each other to design better products.
DJI's factories in Shenzhen include highly sophisticated automated assembly lines, including portions where drones under construction "take off on their own by the hundreds, performing a series of maneuvers over the course of two minutes, then land and continue moving down the manufacturing line". Many of the components for these assembly lines are built in-house.

The Mavic Air was announced on 23 January 2018, for release on 28 January. It is marketed as a smartphone-sized drone that can fit in a jacket pocket.
It features a 12 MP 4K HDR camera, mounted on a 3-axis gimbal, and has a new panorama mode, which stitches together 25 photos in eight seconds to create a "Sphere Panorama". Due to antennas mounted on its landing gear, the drone has a 21-minute flight time and a 2.5 mile range. Like the Spark, the Air also features the "Smart Capture" mode, in which the drone can be controlled by hand gestures.
The release of the Mavic Air 2 was not without controversy, however, as DJI announced that a key safety feature, AirSense, would not be available on models outside the USA. Shortages on components and complexities of production owing to the ongoing COVID-19 crisis at the time were blamed.

Spreading Wings

The Spreading Wings series are mainly industrial UAVs for professional aerial photography, high definition 3D mapping, ultra light search and rescue, and surveillance etc. based on camera gear on board. In 2013, two models have been released: S800 regular and EVO.

Matrice

The Matrice series are designed for industrial applications.
The Matrice 600pro released November 2016, is an industrial drone that inherits everything from the M600 with the addition of improved flight performance and better loading capacity. The M600 now comes with pre-installed arms and antennas to help reduce the setup time. This is perhaps the biggest improvement over the older M600. With a maximum payload of 6 kg the Matrice 600pro can carry all types of payloads including LiDAR.
The Matrice 100 is a fully programmable and customizable drone, launched on July 6, 2015. It has expansion bay and communication ports, which allows developers to add additional components for different purposes.
Matrice 200 series is a range of weatherproof quadcopters from DJI announced in February 2017.
They are designed for industrial applications, including surveying, inspection, search and rescue and firefighting.
The highest spec of the series is the Matrice 210 RTK, which features Real Time Kinematic technology, allowing for precise Geotagging of images captured from the quadcopter.
The Matrice 200 only supports a single camera, mounted either below or above the drone.
The Matrice 210 and 210 RTK add the ability to dual mount cameras to the drone, allowing multiple sensors to be used simultaneously.
In December 2018, an FCC filing reveals the DJI Matrice 200 V2, Matrice 210 V2 and Matrice 210 RTK V2.

Spark

Released in May 2017, the Spark was designed to be an affordable consumer drone that is nevertheless capable of producing high-quality images and video. It features a 12-megapixel camera capable of shooting 1080p video at 30fps. The camera is stabilised mechanically by a 2-axis gimbal. The Spark also carries an advanced infrared 3D camera that helps the drone to detect obstacles in front of it, as well as facilitating hand-gesture control—a feature that was, until the release of the Mavic Air in January 2018, unique to the Spark. In addition to a smartphone app with virtual controller, a physical controller can also be bought, extending the drone's range up to 1.2 miles. The aircraft has a flight duration of up to 16 minutes, but its exhausted battery can easily be swapped out for a charged battery to extend flight time.
There have been multiple complaints that the drone could switch off and fall while flying. DJI responded to this by releasing a mandatory battery firmware update in August 2017.
In November 2019 the Mavic Mini was released, replacing the Spark in DJI's consumer line-up.

Camcorders

Osmo

The Osmo is a camcorder developed by DJI. The camera uses a smartphone to view camera footage and can record 4K and take either 12–16 MP stills. The camera is interchangeable, with the Zenmuse X3, X3 Zoom, X5, and X5R gimbals compatible, and uses the FM-15 Flexi microphone.

Osmo Pocket

On 28 November 2018, DJI introduced its newest version of the Osmo when it unveiled the Osmo Pocket. Designed to be small enough to fit into a pocket or purse, the Osmo Pocket is capable of shooting 4K video at 60 frames per second. It also has features such as ActiveTrack, Motionlapse and 3x3 Panorama.

Osmo Action

Announced on 15 May 2019, the Osmo Action is DJI's first product in the action camera market. It is a direct competitor to the GoPro action camera line with specifications including a 12MP camera sensor, 4K video, HDR video, timelapse modes, and a front-facing full-color screen. The camera also debuted DJI's latest electronic image stabilization technology.
Osmo Action has a CMOS 1/2.3” 12M with a FOV of 145 °F/2.8, an ISO interval for photos between 100-3200 and for video is between 100-3200. The camera is natively waterproof up to 11 meters and can resist to a fall of 1 meters. It can record up to 4K at 60 fps and can be charged by internal USB-C port.

Zenmuse gimbal-cameras

Zenmuse series of gimbal cameras are a mixed system made of a compact camera and a 3-axis gimbal, designed as a part of a modular system, for example attached to UAVs. The 2019 Zenmuse X7 gimbal camera features a camera with interchangeable 4 prime DJI DL-mount lenses.

Gimbals and stabilization platforms

Osmo Mobile

Not actually a camcorder, similar to the Osmo, it instead relies on the user's smartphone as the camera. Most smartphones are accepted into the gimbal with a width range of 2.31–3.34 inch. The original Osmo Mobile has reached its end-of-life and has been replaced with a second generation.

Osmo Mobile 2

Announced after CES, the DJI Osmo Mobile 2 is the successor to the original Osmo Mobile. Still reliant on a smartphone camera, the Osmo Mobile 2 was a refinement adding multiple shot modes and increasing the battery life to 15 hours. With the rise of Instagram Stories, the Osmo Mobile also allows the gimbal to be placed in portrait mode.

Osmo Mobile 3

Announced on August 13, 2019, the Osmo Mobile 3 is the third smartphone stabilizer from the Osmo family of products. The new Osmo Mobile 3 features the return of the front-facing trigger which was missing on the previous generation. The big design improvement is the foldable frame which increases portability. Another feature from DJI is the ability of the gimbal to charge smartphones from the integrated battery. It's cheaper than its predecessors and is designed for the social media crowd.

Goggles

The DJI FPV series are head-mounted displays designed for FPV drone flying. There are two different product lines in the FPV series: the DJI Goggles and the Digital FPV System. The DJI Goggles is designed to interface with DJI-branded drones, combining dual LCD display screens, wireless connectivity and direct photo and video capture control into one pair of goggles. In November 2017, DJI also released DJI Goggles RE, which featured a new, more rugged metallic matte black casing and compatibility with racing quadcopters. The DJI Digital FPV System is a standalone system designed for non-DJI brand or custom-built drones, consisting of an action camera, an FPV goggles, a flight control/signal transmission module and a remote controller.

Educational robots

RoboMaster S1

On 11 June 2019, DJI unveiled the RoboMaster S1, its first consumer ground drone, named after DJI's annual RoboMaster robot combat competition, of which it is now an unofficial mascot. The S1 is a tank-like rover remotely controlled via Wi-Fi and app on Microsoft Windows, Apple iOS and Google Android mobile devices, with features such as spring-dampened beam axle front suspension, four omnidirectional 12-roller Mecanum wheels that allow agile strafing, a 1080p FVP camera mounted within a 2-axis gimbal turret, and the ability to "fight" other S1 units via either an infrared beam illuminator or a coaxial gel blaster gun, which register hit points for match scoring.
Designed to be an "advanced educational robot", the user has to assemble the S1 from loose parts out of the box and learn to program its AI functionality. Both Scratch and Python are programming languages employed by DJI along with app learning modules to teach the end user how to code.

RoboMaster EP

The DJI RoboMaster EP is the second educational robot from the RoboMaster line, officially released on March 9, 2020, although it was first teased in a YouTube RoboMaster S1 commercial dated on November 25, 2019.
The EP shares similar chassis and Mecanum wheel designs with the S1, is compatible with multi-party hardware, supports multiple software platforms and has an open SDK. The new hardwares include high-performance servos, robotic arms, grippers, infrared depths sensors, sensor transfer, modules and power transfer modules, as well as more than 50 programmable modules. The steering gear of the RoboMaster EP can be customized through a programming interface. The EP supports more than 20 third-party sensors and open-source hardware such as Micro Bit, Arduino and Raspberry Pi.
