1 00:00:08,880 --> 00:00:10,240 We've all seen them. 2 00:00:10,240 --> 00:00:15,760 The stunning aerial cinematic shots in TV shows and films captured from the air. 3 00:00:15,760 --> 00:00:18,280 Not so long ago, video and photography like this 4 00:00:18,280 --> 00:00:22,360 was limited to experienced pilots and expensive productions. 5 00:00:22,360 --> 00:00:24,320 But with the fast progression of technology 6 00:00:24,320 --> 00:00:26,160 and more accessible costs, 7 00:00:26,160 --> 00:00:31,040 flying a drone is a hobby that's becoming more and more popular today. 8 00:00:31,040 --> 00:00:33,200 Technically, the correct terminology 9 00:00:33,200 --> 00:00:39,040 for what we think of as drones is an unmanned aerial vehicle or UAV for short. 10 00:00:39,040 --> 00:00:42,800 These range from unmanned surveillance aircraft used by the military 11 00:00:42,800 --> 00:00:47,160 right down to the remote controlled aircrafts you can find in all toy shops. 12 00:00:47,160 --> 00:00:48,440 The drones we'll be looking at during 13 00:00:48,440 --> 00:00:51,120 this video series are known as quad copters, 14 00:00:51,120 --> 00:00:52,520 which use a series of propellers 15 00:00:52,520 --> 00:00:57,200 to create lift and can be maneuvered very easily in the air. 16 00:00:57,200 --> 00:01:01,040 Modern technology has made the quality and fly ability of these drones 17 00:01:01,040 --> 00:01:05,920 much more accessible to both beginners and more experienced pilots. 18 00:01:05,920 --> 00:01:08,480 Brands such as DJI and Parrot 19 00:01:08,480 --> 00:01:11,520 make some of the best and highest quality drones on the market 20 00:01:11,520 --> 00:01:14,920 that are capable of captureing awesome aerial photography and video 21 00:01:14,920 --> 00:01:17,000 that are suitable for amateur photographers 22 00:01:17,000 --> 00:01:20,920 right through to high end video production companies. 23 00:01:20,920 --> 00:01:22,840 During this video series, 24 00:01:22,840 --> 00:01:26,600 we're going to discuss a variety of topics that will give you a great platform 25 00:01:26,600 --> 00:01:29,000 to begin your drone flying adventures 26 00:01:29,000 --> 00:01:32,000 covering everything from which drone is right for you. 27 00:01:32,000 --> 00:01:35,520 The legislation and licensing laws in the U.K. 28 00:01:35,520 --> 00:01:37,640 How are set up and fly your drone safely 29 00:01:37,640 --> 00:01:41,200 and many more tips and tricks along the way. 30 00:01:41,200 --> 00:01:42,800 In this first video, 31 00:01:42,800 --> 00:01:45,680 we're going to look at the technology behind a quadcopter drone 32 00:01:45,680 --> 00:01:48,560 such as the Mavic 2 Pro, which we have here. 33 00:01:48,560 --> 00:01:52,920 Controlled by a joystick on the controller by a pilot on the ground, 34 00:01:52,920 --> 00:01:55,520 The operation of most consumer drones 35 00:01:55,520 --> 00:01:58,960 are no more complex than playing a video game. 36 00:01:58,960 --> 00:02:03,600 However, behind this simple user interface are an accelerometer, 37 00:02:03,600 --> 00:02:06,520 a gyroscope and other complex technologies 38 00:02:06,520 --> 00:02:11,400 working to make the mechanics of drone flight as smooth as possible. 39 00:02:11,400 --> 00:02:13,440 Let's start with the controller. 40 00:02:13,440 --> 00:02:15,480 To those that are familiar with gaming, 41 00:02:15,480 --> 00:02:18,160 you can see it resembles many game consoles, controllers 42 00:02:18,160 --> 00:02:24,400 on the market with two thumb sticks and a series of dials and buttons. 43 00:02:24,400 --> 00:02:27,400 The majority of controllers work in sync with a smart device 44 00:02:27,400 --> 00:02:29,440 such as a smartphone or a tablet, 45 00:02:29,440 --> 00:02:33,400 which plugs in to allow the pilot to see the video feed from the aircraft. 46 00:02:33,400 --> 00:02:35,440 Information such as distance 47 00:02:35,440 --> 00:02:38,080 altitude and battery levels, as well as controlling 48 00:02:38,080 --> 00:02:42,320 many of the settings used in the devices touchscreen. 49 00:02:42,320 --> 00:02:45,160 Inside the drone, we have an accelerometer, 50 00:02:45,160 --> 00:02:49,120 an altimeter that feeds the drone information about its speed 51 00:02:49,120 --> 00:02:52,280 and direction, altitude, as well as a gyroscope 52 00:02:52,280 --> 00:02:56,720 that controls the rotation and helps keep the drone balanced. 53 00:02:56,720 --> 00:02:58,960 Most drones have built in GPS 54 00:02:58,960 --> 00:03:02,760 the locks on some multiple satellites that track your aircrafts positioning. 55 00:03:02,760 --> 00:03:06,960 All of these sensors work together to create an ultra stable flight, 56 00:03:06,960 --> 00:03:10,120 allowing your drone to hover stationary in a fixed position 57 00:03:10,120 --> 00:03:12,880 when you release all controls, 58 00:03:12,880 --> 00:03:15,320 many safety features such as obstacle avoidance 59 00:03:15,320 --> 00:03:17,840 and return to home features have also been developed 60 00:03:17,840 --> 00:03:22,400 to make flying your drone simple and worry free as possible. 61 00:03:22,400 --> 00:03:28,120 If we take a look at our DJI Mavic 2 Pro here, we will talk through each component 62 00:03:28,120 --> 00:03:31,920 at the front we can see a camera which is mounted on a gimbal. 63 00:03:31,920 --> 00:03:35,680 A gimbal is a system that's used to keep the camera steady during flight. 64 00:03:35,680 --> 00:03:37,760 And get silky smooth video. 65 00:03:37,760 --> 00:03:41,160 We can control the angle of our camera in the gimbals settings. 66 00:03:41,160 --> 00:03:44,400 We'll look at that in more detail later in this series. 67 00:03:44,400 --> 00:03:47,440 The main body of the drone houses, the battery compartment, 68 00:03:47,440 --> 00:03:52,520 as well as a series of sensors that assist obstacle detection and avoidance. 69 00:03:52,520 --> 00:03:55,240 And finally, we have the propeller arms 70 00:03:55,240 --> 00:04:01,840 in this model of aircraft can fold away for easy storage. 71 00:04:01,840 --> 00:04:06,520 As the name quadcopter suggests, our aircraft uses four propellers. 72 00:04:06,520 --> 00:04:10,600 The propellers are the main component that allow your aircraft to fly 73 00:04:10,600 --> 00:04:13,520 as they begin to rotate the shape of the propellers, forces, 74 00:04:13,520 --> 00:04:17,720 the air traveling above the propellers to move faster than the 75 00:04:17,720 --> 00:04:21,440 air below, creating difference in air pressure that is known as lift. 76 00:04:21,440 --> 00:04:24,760 If all four propellers rotate fast enough at the same speed, 77 00:04:24,760 --> 00:04:29,400 the aircraft will begin to climb upwards. And by decreasing the speed again, 78 00:04:29,400 --> 00:04:32,680 we can start to bring our aircraft back down. 79 00:04:32,680 --> 00:04:35,200 If we increase the speed of the rear two propellers 80 00:04:35,200 --> 00:04:37,240 and decrease the speed of the front two, 81 00:04:37,240 --> 00:04:41,160 we keep the same amount of lift to keep our drone stable. 82 00:04:41,160 --> 00:04:43,360 But it now tilts forward, 83 00:04:43,360 --> 00:04:47,760 allowing us to move the aircraft straight ahead or pitch forward. 84 00:04:47,760 --> 00:04:50,440 And if you want to move backwards, we do the opposite 85 00:04:50,440 --> 00:04:54,880 and speed up the front two, and slow down the back two. 86 00:04:54,880 --> 00:05:00,960 The same idea applies with moving left or right a movement known as a roll. 87 00:05:00,960 --> 00:05:04,680 We speed up and slow down the left and right pairs of motors. 88 00:05:04,680 --> 00:05:08,760 The final movement we can control is known as the yaw, 89 00:05:08,760 --> 00:05:10,880 which means to rotate the aircraft either 90 00:05:10,880 --> 00:05:14,360 in a clockwise or anticlockwise direction. 91 00:05:14,360 --> 00:05:17,800 To do this, we use the diagonally opposite pairs of motors, 92 00:05:17,800 --> 00:05:24,760 which rotates in opposite directions to allow us to rotate the aircraft. 93 00:05:24,760 --> 00:05:28,440 Now we have a basic understanding of how a drone works. 94 00:05:28,440 --> 00:05:29,880 In the next video, 95 00:05:29,880 --> 00:05:35,240 we'll look at what we need to do to fly safely and legally in the UK.
