Drones, drones, or drones! Really, we may have heard countless "unmanned aerial vehicles" this year, and even our ears have been "grinded up" by this word. But this is the case, to show that the drone really "fly".
Perhaps for most people, the drone is just a quad-axis aircraft with a camera and radio control. However, more and more four-rotor UAVs now have built-in sensors that help them achieve autonomous flight while also enabling over-the-horizon flights.
Next, let's take a look at the seven highly-focused four-rotor drones in 2014 for the US technology media CNET inventory.
DJI Phantom 2 Vision+
This is an updated version of DJI Phantom 2 Vision, released in April this year.
The DJI Phantom 2 Vision+ is the longest-running drone in the current consumer-grade quadrotor drone, which can reach 25 minutes. Compared to the previous version, Vision+ adds a high-precision three-axis gyro-stabilized pan/tilt that actively cancels the camera's jitter, making it a new visual experience for vertical down-shooting, like an aerial tripod. At the same time, Vision+'s WiFi coverage has increased to 700 meters, allowing users to preset up to 16 waypoints, which allows the drone to better achieve autonomous flight.
Specifically, DJI (Dajiang) is an innovative UAV company founded in Shenzhen, China.
Blade 350 QX2 AP Combo RTF
Although the Blade 350 QX2 doesn't look as refined as Vision+, it's still cheaper than the Vision $1,299 price. The 350 QX2 features a variable pitch controlled dual-axis brushless track frame and a 1080p camera that can capture 720p/30fps video and download it to mobile devices.
Based on the user's handling experience, or to improve the quality of video capture, this drone offers three different modes of flight. Most importantly, the 350 QX2 also provides autonomous return.
The recently released 350 QX3 AP Combo RTF improves GPS performance and is equipped with a three-axis brushless tracker that carries a 16 megapixel camera for 1080p/60fps video.
Parrot Rolling Spider
This drone has appeared on the CES2014 booth, which is the simplest four-rotor drone among the seven drones. Don't underestimate it, the so-called "sparrow is small and complete", in its tiny body equipped with some fairly high-end electronic equipment. Users can control it using a smartphone or tablet.
But unlike the other six quadrotor drones, the Parrot Rolling Spider does not fly autonomously. Although it doesn't last long, it can still bring a lot of fun.
Parrot Bebop Drone
As a follow-up drone model for AR Drone 2.0, Bebop has a F2.2 fisheye lens with a 180-degree viewing angle and a built-in 14 megapixel camera for 1080p full HD video and JPEG or Photos in Adobe DNG RAW format.
Although this drone can be fully controlled using a smartphone or tablet, it can also be operated by the Skycontroller touchpad for those who wish to use physical controls. It provides two joysticks: one to control the camera and the other to control takeoff, landing and emergency shutdown of the engine. At the same time, the touchpad also has a status indicator that shows battery usage and control, and an auto-return button. Of course, users can also control the first view through smartphones and tablets.
Bebop will be available for sale in December this year for $499, which can be purchased at Best Buy and Apple's online or offline stores. If you want to buy Skycontroller at the same time, the price is $899. The drone will also be available in Australia for the same period in December. However, the offer price and distribution channels in the UK have not yet been determined.
DJI Inspire 1
This quadrotor drone is from DJI and is an upgraded version of Phantom 2 Vision+. It is worth mentioning that this is the world's first drone with 4K flying camera, which can record 4K ultra HD video and shoot still photos up to 12 million pixels. The camera features a 94-degree wide-angle fixed-focus lens that supports 360-degree rotation and 125-degree tilt. The Inspire 1 has a new generation of Lightbridge HD video transmission system with a video transmission distance of up to 2 kilometers.
Of course, the Inspire 1 has other notable new features, and the corresponding price is its more expensive price: $2,900 in the US, £2,380 in the UK, and the price in Australia in Australia. AUD 4130.
By the way, Inspire 1 has a very interesting Chinese name called "Enlightenment".
3D Robotics IRIS+
This is a drone that CNET can't wait to get. Among the many features of IRIS+, "Follow Me" is a commendable feature that users can set to track any Android device with GPS enabled.
In addition, this drone also has a dedicated App: DroidPlanner, through which users can draw drone flight routes on a tablet or mobile app, and then allow the drone to fly along the flight path.
Encouragement Award: Parrot Jumping Sumo
Perhaps it would be more appropriate to think of it as a robot. As its name suggests, this drone needs to jump to move it around. It can jump to a height of 2.5 feet (about 0.76 meters) and shoot video from the ground through the front camera.
Industrial Computers and commercial computers have always been inextricably linked. They each have their own application areas, but they affect each other and promote each other, reflecting the progress of science and technology. At present, it is better to do Sanqi Tuoda in China and Advantech in Taiwan. Advantech has a higher reputation, but its price is higher. The industrial computer site can be embedded in the machine, cabinet or placed on the operation table, and it can be used as a man-machine display interface. It is used in telecommunications, electric power, multimedia, national defense, automation equipment, manufacturing and other fields. It is used as a man-machine interface, thin client, PLC and POS communication and control terminals. Digital hospitals are used as bedside service terminals and outpatient terminals to improve hospital service and management. Banks, shopping malls, hotels, railway stations, buses, subway stations, parks and other public places as media (advertisement) players or inquiry terminals. High-end residential quarters are used as home service terminals to implement intercom, message, cost inquiry, product order, home appliance management, temperature and humidity control, etc.
