00:00:00.160 --> 00:00:08.240
okay first off everyone needs to come down i know it's not really a hoverboard

00:00:04.880 --> 00:00:09.920
and i agree with you it's a stupid name

00:00:08.240 --> 00:00:13.759
it doesn't hover i get it they're on wheels nothing has

00:00:12.000 --> 00:00:17.920
to do with hovering around the office we usually call them swagways but the

00:00:15.839 --> 00:00:21.359
internet seems to have decided that they are now called hoverboards and outside

00:00:20.160 --> 00:00:26.400
of that there doesn't seem to be a universally accepted name other than

00:00:23.680 --> 00:00:29.519
self-balancing boards which is too long and not catchy and no one calls it that

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

00:00:33.360 --> 00:00:39.920
being said hoverboards are essentially a horizontal

00:00:37.200 --> 00:00:44.559
self-balancing board with wheels on each end controlled by the rider's feet and

00:00:42.559 --> 00:00:50.079
as cool as it is the technology that makes up the hoverboard hoverboard

00:00:46.960 --> 00:00:51.600
whatever is not that new other devices

00:00:50.079 --> 00:00:56.640
using similar technology have been around for consumers since around 2001

00:00:54.160 --> 00:01:01.520
when the original segway was unveiled this segway had two wheels one on each

00:00:58.800 --> 00:01:05.560
side was self-balancing and had a set of handlebars so that the rider could

00:01:03.359 --> 00:01:11.200
balance more easily and although hoverboards don't have the handlebars

00:01:08.720 --> 00:01:16.240
both vehicles operate off a concept called the inverted pendulum which is a

00:01:13.840 --> 00:01:21.680
pendulum that has a center of mass namely your body above its pivot point

00:01:19.680 --> 00:01:26.400
amazingly enough inverted pendulum devices have been around since the early

00:01:23.600 --> 00:01:30.400
1970s though it's not surprising you didn't see people riding them down the

00:01:28.000 --> 00:01:34.720
streets back then you see the processing needed to make quick corrective

00:01:32.000 --> 00:01:38.880
calculations has to be extremely fast and accurate not only that but the

00:01:36.479 --> 00:01:44.320
equipment has to be highly sensitive all of these things add up to what was until

00:01:41.280 --> 00:01:45.920
recently a very expensive combination

00:01:44.320 --> 00:01:50.560
another inherent property of the inverted pendulum is that compared to a

00:01:48.240 --> 00:01:55.360
standard pendulum it's incredibly unstable therefore the pivot point aka

00:01:52.960 --> 00:01:59.840
the board must make constant corrective movements to balance the center of mass

00:01:57.439 --> 00:02:03.840
which is the rider almost like balancing a pull on your palm and having to run

00:02:01.759 --> 00:02:08.720
around to keep it upright so how does a self-balancing device counteract this

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

00:02:10.160 --> 00:02:16.480
mainly they use gyroscopic sensors which use multiple gimbal rings to determine

00:02:15.040 --> 00:02:20.720
an angle you can learn more about gimbals here and an accelerometer based

00:02:18.959 --> 00:02:24.959
on leveling sensors to detect the board's pitch and angle the board uses

00:02:23.280 --> 00:02:29.200
this information to take corrective measures and keep itself upright for

00:02:27.200 --> 00:02:33.120
example if you start to lean forward the board will try to start rolling forward

00:02:31.200 --> 00:02:36.720
at the exact speed necessary to keep you from falling on your face unless you

00:02:35.040 --> 00:02:40.239
straight up try to fall on your face then that will probably happen

00:02:38.480 --> 00:02:44.640
interestingly enough these boards have two sets of these sensors on each side

00:02:42.640 --> 00:02:49.200
with a joint in the middle separating the two halves this allows the size to

00:02:47.200 --> 00:02:53.040
move independently so if you want you can say spin in a circle if you just

00:02:51.360 --> 00:02:56.400
lean one foot forward and one foot backwards pretty cool right so what's

00:02:55.040 --> 00:03:01.040
going to happen a few years down the road well since self-balancing boards

00:02:58.640 --> 00:03:04.800
just kind of became popular recently there might be quite a few possibilities

00:03:02.959 --> 00:03:08.879
since these boards are now becoming affordable we might see many other types

00:03:07.040 --> 00:03:13.599
of self-balancing devices in the near future like the self-balancing unicycle

00:03:11.280 --> 00:03:18.319
we did a video on not surprisingly though these devices have been banned in

00:03:15.760 --> 00:03:22.640
many major cities in the u.s and uk due to safety concerns these bans are

00:03:20.400 --> 00:03:25.840
limited to public places though so i wouldn't worry about having a swat team

00:03:24.400 --> 00:03:29.680

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

00:04:19.680 --> 00:04:25.520
watching i thought about doing this video on a hoverboard but they've been

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

00:04:27.600 --> 00:04:32.720
it dislike it if you disliked it check out our Channel Super Fun video where

00:04:30.960 --> 00:04:36.080
we've made videos on hoverboards including jousting each other also

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
