In the middle we have a motor, and we also have a gear in it, and we use the gear to transfer the circulation of the motor.

Gears

A gearhead

That little gear there switches back and forth to change direction.

So that rod, connected to the gearshift lever on the steering post, comes down here

A tiny cog in the great wheel of evolution.

Cube Gears

Gear in.

So, that's a finished gear.

Roads, cones and wheels.

Clutch in, move gear, pedal down, clutch out, now all together.

(all) Clutch in, move gear, pedal down, clutch out.

Stop complaining and bring the gear over here.

Let's put the gear here.

So, we have a motor here on the left, and it goes through a gear train.

Display gears inside the cube

Every one of these circles is a cog, a stack of cogs, and this thing is as big as a steam locomotive.

Sorry, the gears look all alike.

The front wheels rotate like this.

And the gears work in water as well.

You're the most adorable cog I've ever seen.

He's merely a grain of sand in the wheels of our machine!

So starting from a three dimensional ping sound system, a vibrating vest, a click wheel with voice commands, a leg strip, even a shoe that applies pressure to the foot.

For most small wheeled robots, they use a method called differential steering where the left and right wheel turns the opposite direction.

So let's talk about the memory. The memory is very like the memory of a computer today, except it was all made out of metal, stacks and stacks of cogs, 30 cogs high.

If I spin this pulley, the small one's going to spin much faster.

ES Well, imagine that you have two gears of a watch, a big one and a small one.

Clean it up, Chief, and nail down the new gear.

You can do gears and nuts and bolts that you can buy at Whole Foods.

I counted every turn of the wheels. May I come in?

Think of the satisfaction of being a small cog in the great wheel of humanity known as Lonesome Rhodes.

There are 12 pairs of 50 1 reductions, so that means that the final speed of that gear on the end is so slow that it would take two trillion years to turn once.

The world is a wheel.

After many years of bending gears with a pair of pliers, I made that tool, and then I made this other tool for sort of centering gears very quickly sort of developing my own little world of technology.

It's on the roof of the world.

The wheel is turning.

For example, in this case, even though the left and right wheel is connected with a single axle rotating at the same angle of velocity.

If set, mouse wheel goes to previous or next unit, otherwise it scrolls text

Then we sort of raise our eyebrows, move our eyes, give the other person the idea it's their turn to talk.

One was a passion for rodents.

So instead, it slides in grooves on the outside of the head.

On land, life turned a corner. Jaws formed first teeth came later.
