I'm Elliot from Design Squad, and I'm here with Arun, June and Njuere.

Today, we're making bristle bots.

These are made out of toothbrush heads, a coin battery, and a pager motor.

The motor uses an eccentric weight, which is off-centered and balanced on one side, which makes it vibrate.

(making vibration noises) So the vibration is what makes it move.

ELLIOT: I can feel the vibrations through the bristles on the bristle bot.

I built an arena.

ARUN: The arena is just a bunch of pipe cleaners taped together.

When a bristle bot hits something, all it does is it bounces off and goes in a different direction.

My bristle bot was going in a circle because I put my pager motor on top of the battery, so it's really high up.

But if I put them next to each other, maybe it'll work better.

Now mine is going in a straight line.

I'm putting a bunch of toothbrush heads together so I can use this big motor.

It's kind of like a helicopter.

It just goes in random ways.

I love it because I'm crazy like that, too.

It feels like a massage because when you have a massage, it's like vibrating your skin, and so is this.

Elliot, do you want a neck massage?

Yeah, sure!

It feels good.

I've made a giant bristle bot-type creation.

There's a big piece of wood on the bottom and a fan motor with a big rubber cork.

Instead of bristles on the bottom, I have five pads.

(vibrating loudly) I can literally see the piece of wood vibrating.

Me and my sister are building a maze.

We're having a competition.

Go!

May the best one win!

Oh!

You can't do that!

(laughing) I bumped you out.

Instructions to make your own bristle bots are on the Design Squad website.

JUNE: Hey!

That was a close one.

I swear I would have won.
