Robo-Wheel | Design Squad


(buzzing like an engine) Robo, robo wheel Go round and round and round Robo robo wheel Go ro-rollin’ down. I’m Nate from Design Squad,
and I’m here with: This is a robo wheel. It’s made from two paper plates
and some string. To start it off,
I give it a little turn, and when it starts
to come back the other way, I pull to help it out. (revving like an engine) (beat boxing)
Let go, let’s go Robo robo wheel DESI:
We’re trying to make these move really fast on the driveway
and race them. ZARA: We have to release these
at exactly the right point, or it won’t work. Ah! Mine was spinning backwards. One… You’ve got to release it
at the right time. NATE:
When the wheel turns, it winds the string. So when it stops and the
string is all wound up, potential energy. Now when it spins fast,
boom! Kinetic energy. One, two, three, go! Ho, ho, ho. I think I got
a jump on you there. Good race, though. We’re building a ramp for the robo wheels to make
a jump off of. Blast off! (laughing) Sweet! It’s robo wheel bowling! (robotic voice):
Robo bowling. Go! Oh! Go. Oh! Go. Yay! ANNA:
We’re decorating the robo wheels and I’m hoping
that when it starts spinning, it looks like it’s kind
of all blending together. When it spins faster, I think it’s going to look
really pretty, like a firework exploded. ZARA:
We should definitely take a look at it
while it’s spinning. And they’re really fun to
decorate because you can really personalize it. AJ: The colors are
blending together. NATE: I love seeing it
change speed because then the design changes. Now, the robo wheel
is a demonstration of something called
a fly wheel– a wheel that’s spinning
to store rotational energy. We can see the same
kind of rotational energy that we have in the robo wheel in the bicycle wheel. So, that’s part of what helps
keep you coasting along even when you’re not pedaling. Zoom! Kinetic energy. Instructions to make
your own robo wheel are on the Design Squad website. ZARA:
That looks really, really cool. Looks like a flying saucer.
