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.
