1
00:00:00,160 --> 00:00:08,240
okay first off everyone needs to come down i know it's not really a hoverboard

2
00:00:04,880 --> 00:00:09,920
and i agree with you it's a stupid name

3
00:00:08,240 --> 00:00:13,759
it doesn't hover i get it they're on wheels nothing has

4
00:00:12,000 --> 00:00:17,920
to do with hovering around the office we usually call them swagways but the

5
00:00:15,839 --> 00:00:21,359
internet seems to have decided that they are now called hoverboards and outside

6
00:00:20,160 --> 00:00:26,400
of that there doesn't seem to be a universally accepted name other than

7
00:00:23,680 --> 00:00:29,519
self-balancing boards which is too long and not catchy and no one calls it that

8
00:00:28,640 --> 00:00:34,719
so we're just going to call them hoverboards so that it's easier for everyone to understand so with that

9
00:00:33,360 --> 00:00:39,920
being said hoverboards are essentially a horizontal

10
00:00:37,200 --> 00:00:44,559
self-balancing board with wheels on each end controlled by the rider's feet and

11
00:00:42,559 --> 00:00:50,079
as cool as it is the technology that makes up the hoverboard hoverboard

12
00:00:46,960 --> 00:00:51,600
whatever is not that new other devices

13
00:00:50,079 --> 00:00:56,640
using similar technology have been around for consumers since around 2001

14
00:00:54,160 --> 00:01:01,520
when the original segway was unveiled this segway had two wheels one on each

15
00:00:58,800 --> 00:01:05,560
side was self-balancing and had a set of handlebars so that the rider could

16
00:01:03,359 --> 00:01:11,200
balance more easily and although hoverboards don't have the handlebars

17
00:01:08,720 --> 00:01:16,240
both vehicles operate off a concept called the inverted pendulum which is a

18
00:01:13,840 --> 00:01:21,680
pendulum that has a center of mass namely your body above its pivot point

19
00:01:19,680 --> 00:01:26,400
amazingly enough inverted pendulum devices have been around since the early

20
00:01:23,600 --> 00:01:30,400
1970s though it's not surprising you didn't see people riding them down the

21
00:01:28,000 --> 00:01:34,720
streets back then you see the processing needed to make quick corrective

22
00:01:32,000 --> 00:01:38,880
calculations has to be extremely fast and accurate not only that but the

23
00:01:36,479 --> 00:01:44,320
equipment has to be highly sensitive all of these things add up to what was until

24
00:01:41,280 --> 00:01:45,920
recently a very expensive combination

25
00:01:44,320 --> 00:01:50,560
another inherent property of the inverted pendulum is that compared to a

26
00:01:48,240 --> 00:01:55,360
standard pendulum it's incredibly unstable therefore the pivot point aka

27
00:01:52,960 --> 00:01:59,840
the board must make constant corrective movements to balance the center of mass

28
00:01:57,439 --> 00:02:03,840
which is the rider almost like balancing a pull on your palm and having to run

29
00:02:01,759 --> 00:02:08,720
around to keep it upright so how does a self-balancing device counteract this

30
00:02:06,399 --> 00:02:12,640
well with a crap ton of math first off but we aren't going to get into that

31
00:02:10,160 --> 00:02:16,480
mainly they use gyroscopic sensors which use multiple gimbal rings to determine

32
00:02:15,040 --> 00:02:20,720
an angle you can learn more about gimbals here and an accelerometer based

33
00:02:18,959 --> 00:02:24,959
on leveling sensors to detect the board's pitch and angle the board uses

34
00:02:23,280 --> 00:02:29,200
this information to take corrective measures and keep itself upright for

35
00:02:27,200 --> 00:02:33,120
example if you start to lean forward the board will try to start rolling forward

36
00:02:31,200 --> 00:02:36,720
at the exact speed necessary to keep you from falling on your face unless you

37
00:02:35,040 --> 00:02:40,239
straight up try to fall on your face then that will probably happen

38
00:02:38,480 --> 00:02:44,640
interestingly enough these boards have two sets of these sensors on each side

39
00:02:42,640 --> 00:02:49,200
with a joint in the middle separating the two halves this allows the size to

40
00:02:47,200 --> 00:02:53,040
move independently so if you want you can say spin in a circle if you just

41
00:02:51,360 --> 00:02:56,400
lean one foot forward and one foot backwards pretty cool right so what's

42
00:02:55,040 --> 00:03:01,040
going to happen a few years down the road well since self-balancing boards

43
00:02:58,640 --> 00:03:04,800
just kind of became popular recently there might be quite a few possibilities

44
00:03:02,959 --> 00:03:08,879
since these boards are now becoming affordable we might see many other types

45
00:03:07,040 --> 00:03:13,599
of self-balancing devices in the near future like the self-balancing unicycle

46
00:03:11,280 --> 00:03:18,319
we did a video on not surprisingly though these devices have been banned in

47
00:03:15,760 --> 00:03:22,640
many major cities in the u.s and uk due to safety concerns these bans are

48
00:03:20,400 --> 00:03:25,840
limited to public places though so i wouldn't worry about having a swat team

49
00:03:24,400 --> 00:03:29,680

techwiki in the how did you hear about us section alright guys thanks for

63
00:04:19,680 --> 00:04:25,520
watching i thought about doing this video on a hoverboard but they've been

64
00:04:23,040 --> 00:04:29,440
more or less banned at the office so i don't know like the video if you liked

65
00:04:27,600 --> 00:04:32,720
it dislike it if you disliked it check out our Channel Super Fun video where

66
00:04:30,960 --> 00:04:36,080
we've made videos on hoverboards including jousting each other also

67
00:04:34,720 --> 00:04:41,440
comment in the video and not in the video description comment in the comment section down below with any other videos
