DJI Phantom 4

DJI phantom 4 elegant appearance of the streamlined, plus integrated PTZ design, and quick demolition of the propeller, so that disassembly more convenient, more stable lock, for the fierce flight to provide security. Not only increased the battery life, but also increased the speed of flight. To 20 meters per second (72 kilometers per hour) to maintain high-speed flight, the operation more agile, more fun experience.

The new Phantom 4 will be able to say is a cross-era of unmanned aerial vehicle products, brings together a number of black technology, people shines. The introduction of "computer vision" and "machine learning" technology has made consumer-level UAVs more intelligent, thinking and learning, and more user-friendly. "Smart tracking" is one of the biggest embodiment of the previous generation to rely on remote control on the GPS positioning different, we control the UAV, no longer need to mention the remote control around running, by manipulating Phantom 4 mobile phone or iPad, select After the object to be tracked, the 3D stereo image is calculated by 5 images (camera, 2 visual positioning, 2 obstacle avoidance) sensors on the UAV, and the smooth trajectory shooting is selected. In actual flight, the Phantom 4 with the T stage models back and forth in the pace of the model, or irregular running, always maintain a fixed distance, the camera lens is firmly locked in the object to be followed.

In Case You Missed It: Live at DJI Headquarters

I recently visited DJI headquarters to go Behind the Brand of one of the hottest drone makers and OEMs developing tools for filmmakers and video creators.The highlight was definitely the new Mavic Pro. It's is a small yet powerful drone that turns the sky into your creative canvas easily and without worry, helping you make every moment an aerial moment. Its compact size hides a high degree of complexity that makes it one of DJI’s most sophisticated flying cameras ever. Twenty-four high-performance computing cores, an all-new transmission system with a 4.3-mile range, five vision sensors and a 4K camera stabilized by a three-axis mechanical gimbal are at your command with just a push of your thumb or a tap of your finger.
Helping you fly farther.

Inside the Mavic’s pocket-sized remote controller is DJI’s brand-new OcuSync transmission technology, with a range of 4.3 miles and full HD 1080p video streaming.No bumps and scapes.

An unprotected drone could hit obstacles during long-distance flight or when descending from an inadequate height in "Return to Home" mode. The Mavic uses FlightAutonomy technology to sense obstacles up to 49 feet away. It can then bypass these obstacles or brake to hover, reducing accidents even when flying beyond visual range.

Share! NYC principal says Trump presidency is 'more troubling' than 9/11

The principal at a progressive Manhattan private school told parents in an email last week that the Trump presidency was more troubling than Vietnam, the assassination of Martin Luther King Jr., the September 11 attacks and Watergate, The Post has learned.

Steve Nelson’s scorching missive managed to roil several parents at the $46,000 per year Calhoun School – no small feat considering the Upper West Side bastion’s blaring liberal bent.
“It was inappropriate, it was offensive, it was condescending,” said one parent. “This is a liberal school. So I guess that’s the approach. But this was too much. To compare this to 9-11 – I think that’s just too much.”
Nelson emailed a series of anguished ruminations on Donald Trump’s ascent to Calhoun parents, simultaneously calling for non-partisanship while skewering the billionaire’s policies.
In a message sent last week, Nelson, who also teaches journalism at the pre-K through 12 campus, noted his intimate familiarity with several recent catastrophes – including 9-11.
“I watched soot-covered New Yorkers grimly trudging north on West End Avenue on September 11, 2001,” Nelson wrote. “I am more troubled now.”
Elsewhere in the lengthy missive, Nelson acknowledged the theoretical need to avoid political bias in a school environment. “One in my position must be scrupulous in avoiding partisanship,” he said.
But he later asserted in the same message that “there are matters that transcend political diversity.”
“The ways in which equity and equality are now threatened are deeply troubling, including the constitutionally suspect and arguably discriminatory efforts to restrict or prohibit immigration based on religion and/or ethnicity,” he wrote.

Inspire series of DJI unmanned aerial vehicles of the second generation - Inspire 2（Ⅱ）

In order to take into account the transport of portable and 360-degree PTZ barrier-free vision, Inspire 2 a total of three forms - mode of transport, landing mode and flight mode. Only in the transport mode, we can put it in the box, and installed in the camera module, you need to first press the 5 power button to change to the landing mode.

Inspire2 biggest change is the matte gray aluminum casing, front binocular camera and FPV camera module, stout motor, more robust paddle lock mechanism and a new design of the battery installation. In addition, Inspire2 tripod becomes more slim and concise, strength seems to have improved.

Carefully observe the top of the fuselage, we can find another bright spot. As the Inspire2 switch to an aluminum alloy shell, in order to prevent obstacles GPS positioning signal, the top of the GPS part of the open a circular hole, and aluminum alloy cover the same color plastic cover GPS antenna instead, so Inspire2 positioning accuracy should not be shell Material changes are affected in any way.

Because the battery has been inserted from the vertical into the tail, so Inspire1 top of the original battery opening was "eliminated", but the four Y-shaped power indicator and power button has been retained. Behind the battery indicator is a battery lock and two infrared perception system, the perception system can ensure that the UAV in the process of rising will not encounter obstacles to facilitate flying in the indoor flight.

Present Situation UAV of DJI

DJI is currently in the US consumer UAV market share of more than 50% of their biggest rivals in the United States have fallen. This dominance of DJI has made its hardware a platform, and any major UAV software provider will seek to integrate their products with the DJI Mobile Application, Software Development Kit (SDK).

DJI released a number of new products is surprising. DJI on Tuesday released the new "Enlightenment" Inspire 2 and  Phantom 4 Pro unmanned aerial vehicles. Last week, DJI released a new version of Matrice unmanned aerial vehicles. Last month, the DJI also launched a new "Royal" series Mavic unmanned aerial vehicles. Even more frightening is that DJI new UAVs all new products is basically just in competition with their own.

Currently on the market there are FreeFly, Ascending Technologies and other companies to develop very high-end unmanned aerial vehicles, their performance can be higher with the DJI UAV, but they are priced at more than 15,000 US dollars, is the new DJI Matrice 600 Pro unmanned aircraft tripled. In the price range of $ 1,000 to $ 6,000, there are four different types of UAVs in DJI. The cheapest models are actually better than those of other companies.

Bigger is now able to extend new features from one product line to other product lines, just as Apple's fingerprint sensor was initially used for mobile phones, but now also landed on the same notebook.DJI first extended the important function of the elf on the Inspire UAV, and then extended to the Mavic product line.

DJI "Mavic" foreign media evaluation summary of the excellent combination of portability and performance

DJI is undoubtedly the most successful enterprise in China's technology industry in recent years, because it is a native Chinese brand, but in the years to grow into the world's first civilian UAV brand, and even defeated, including 3D Robotics US companies (3D Robotics has switched to do the software).

After all, almost all foreign companies have core technologies and resources (such as Android systems, processors, etc.) in many areas, such as smart phones, PCs, software, games, etc., China's DJI to do the world's first It is not easy. Such as the latest "Royal" Mavic Pro unmanned aerial vehicles, almost won the foreign media unanimously spoke highly of the continent itself represents the concept of continuous innovation.

Mavic Pro first innovation is that it can be folded. In fact, this feature changes the general UAV use patterns. Although you may be in the variety show often see UAV aerial photography, but for ordinary consumers, to spend more than 5,000 yuan to buy a portable "toy", in fact, still some difficulties. Obviously, the foldable Mavic Pro alleviates this problem to some extent.

Second, Mavic Pro to keep the portable folding design, but also the largest integrated high-end technology, such as 4K camera, object tracking, a wide range of connection distance, etc., the price is relatively reasonable.

Currently, the only direct competitor on the market with Mavic Pro is GoPro's Karma, which does not recall the Mavic Pro because of its failure. In contrast, almost all foreign media Mavic Pro more worthy of consideration. Then the following, take a look at foreign media on the DJI Mavic Pro evaluation experience summary.
