okay first off everyone needs to come down i know it's not really a hoverboard
and i agree with you it's a stupid name
it doesn't hover i get it they're on wheels nothing has
to do with hovering around the office we usually call them swagways but the
internet seems to have decided that they are now called hoverboards and outside
of that there doesn't seem to be a universally accepted name other than
self-balancing boards which is too long and not catchy and no one calls it that
so we're just going to call them hoverboards so that it's easier for everyone to understand so with that
being said hoverboards are essentially a horizontal
self-balancing board with wheels on each end controlled by the rider's feet and
as cool as it is the technology that makes up the hoverboard hoverboard
whatever is not that new other devices
using similar technology have been around for consumers since around 2001
when the original segway was unveiled this segway had two wheels one on each
side was self-balancing and had a set of handlebars so that the rider could
balance more easily and although hoverboards don't have the handlebars
both vehicles operate off a concept called the inverted pendulum which is a
pendulum that has a center of mass namely your body above its pivot point
amazingly enough inverted pendulum devices have been around since the early
1970s though it's not surprising you didn't see people riding them down the
streets back then you see the processing needed to make quick corrective
calculations has to be extremely fast and accurate not only that but the
equipment has to be highly sensitive all of these things add up to what was until
recently a very expensive combination
another inherent property of the inverted pendulum is that compared to a
standard pendulum it's incredibly unstable therefore the pivot point aka
the board must make constant corrective movements to balance the center of mass
which is the rider almost like balancing a pull on your palm and having to run
around to keep it upright so how does a self-balancing device counteract this
well with a crap ton of math first off but we aren't going to get into that
mainly they use gyroscopic sensors which use multiple gimbal rings to determine
an angle you can learn more about gimbals here and an accelerometer based
on leveling sensors to detect the board's pitch and angle the board uses
this information to take corrective measures and keep itself upright for
example if you start to lean forward the board will try to start rolling forward
at the exact speed necessary to keep you from falling on your face unless you
straight up try to fall on your face then that will probably happen
interestingly enough these boards have two sets of these sensors on each side
with a joint in the middle separating the two halves this allows the size to
move independently so if you want you can say spin in a circle if you just
lean one foot forward and one foot backwards pretty cool right so what's
going to happen a few years down the road well since self-balancing boards
just kind of became popular recently there might be quite a few possibilities
since these boards are now becoming affordable we might see many other types
of self-balancing devices in the near future like the self-balancing unicycle
we did a video on not surprisingly though these devices have been banned in
many major cities in the u.s and uk due to safety concerns these bans are
limited to public places though so i wouldn't worry about having a swat team

watching i thought about doing this video on a hoverboard but they've been
more or less banned at the office so i don't know like the video if you liked
it dislike it if you disliked it check out our Channel Super Fun video where
we've made videos on hoverboards including jousting each other also
