Oh, hello there. I'm just doing a bit of vacuuming...

..with a vacuum cleaner that does it all by itself!

That's clever, isn't it?

BEEP!

I hear a beep, I see a flash, I wonder what they're going to ask.

-Hi, Nina!

-Hi, Nina!

Hi!

We've got a question for you.

What amazing things would we have in the future?

That's a great question.

What amazing things will we have in the future?

I know there are some very exciting things

that some very clever people are working on right now.

-Come to my lab and we'll investigate.

-See you soon, Nina.

-Bye!

-Bye.

I'm going to need some help to answer this one,

and I know just who to ask.

OK, Neurons, time to get to work.

ALL: Neurons at the ready, Nina.

OK. Today's question is...

"What amazing things will we have in the future?"

Which Neuron will be most useful in helping us find the answer?

ALL: Me! Me! Me!

Will it be fabulous Felix?

I can help so very much if you need the sense of touch.

Will it be beautiful Belle?

I send messages to brain from ear.

If there's a sound, I'll help you hear.

Will it be lovely Luke?

For looking and seeing, day or night,

I'll help you with your sense of sight.

Will it be awesome Ollie?

If it's pongy or whiffy but you can't tell,

my messages help your sense of smell.

Or will it be baby Bud?

Sour, salty, bitter or sweet,

I'm your taste buddy whenever you eat!

It's all the Neurons!

ALL: Go, Neurons! Go, Neurons! Go, Neurons!

ALL: Go, Neurons! Go, Neurons! Go, Neurons!

ALL: Go, Neurons!

ALL: All Neurons hip-hop-happy to help, Nina.

Today's question is...

"What amazing things will we have in the future?"

We'll need help from all our Neurons today.

I need to get the lab ready before the experimenters arrive.

Leanna loves reading animal books.

Selma likes gymnastics.

There are new things since my mum was young.

Making new things is fun.

But they both want to know

what amazing things we'll have in the future,

so, today, for one day only,

Leanna and Selma become the experimenters!

-Hi, guys!

-Hi, Nina.

-Hi, Nina.

Welcome to my lab and thanks for your great question -

"what amazing things will we have in the future?"

To find out, let's start by using our senses.

ALL: Whoo-hoo! A senses experiment! We're ready, Nina!

Technology is changing really fast

and it's making our lives easier every day.

But what will we have in the future?

Well, I have a vacuum cleaner that drives itself.

But how about a car that drives itself?

Well, that's just silly!

Cars can't drive themselves, Nina.

Actually, Felix, people are working on them right now.

But I think you guys need to find out more about driving cars

by doing some driving yourselves, in these mini cars! Off you go!

Ah, that's it. On you go, Leanna. Turn that wheel.

Vroom-vroom! Good turn, experimenter! Ha-ha!

Watch out for the desk!

Ha-ha-ha!

Oh, beautifully turned!

That's it! Go for it!

Great driving.

Now when you were driving,

you were doing lots of different things at once. So what were they?

I turned the wheel and I looked around.

-I pushed the pedals.

-Yes.

You had to turn the steering wheel

and use your feet to move the pedals.

And you had to look around, to make sure you didn't bump into anything.

That's a lot of things to do at once.

Driving is hard work, Nina.

It can be, Felix.

But what will cars be like in the future?

Well, have a look at this.

These cars can drive by themselves.

The driver is still sitting behind the steering wheel

but she can read a newspaper because the car's driving itself.

How does a car drive itself, Nina?

Well, the car is actually being driven by a computer.

The computer controls what the car does.

Some very clever people have thought about

all the things you have to do to drive a car.

And they've found a way to make a computer do the same things.

I think we need to go on a bus ride to find out more.

Hmm, where do you think we're going today?

Nina said we were going on a bus ride.

I hope it's a double-decker and we sit in the top!

I do hope there's not a big queue at the bus stop.

I don't think we're going to a bus stop, Neurons.

OK, experimenters, so far we've found out that driving

involves doing LOTS of different things at once

and driverless cars are actually controlled by a computer.

So I've brought you here to see this little bus to find out more!

Now this shuttle bus takes people around this special place,

where lots of scientists work.

But can you see a driver?

-BOTH:

-No.

No-one there, Nina.

That's because this shuttle bus actually drives by itself.

And as a special treat,

I've arranged for US to have a ride on it.

So, come on, let's hop on board!

There you go.

We need to tell the computer which journey we want to take.

So can you press the button for me, Selma?

OK, here we go!

This is amazing!

And VERY quiet!

It's not like a normal bus or car.

And I can't smell any whiffy engine fumes either.

That's because this shuttle bus doesn't have the same type of engine

that most buses and cars have.

It doesn't use petrol.

It uses electricity - we've a big battery to make it move.

We've arrived safely! Well done, shuttle bus.

Did the bus drive us anywhere, Nina?

That's a good question.

Well, the computer that controls the shuttle bus

only knows how to drive along certain journeys.

A person taught it those journeys

so now it can follow them on its own.

In the future, if the computers in cars and vehicles like this

are given enough information,

they could go absolutely ANYWHERE!

So let's go back again.

Oh, there's a parked car ahead.

Mm, how will the shuttle bus spot the car?

It can't see.

Don't worry, Luke.

Although the shuttle bus doesn't have eyes like we do,

it still knows what's around it.

When it senses something in front of it, that it could bump into,

the computer in the shuttle bus makes the shuttle bus stop safely.

And off we go!

That was fun, wasn't it?

-BOTH:

-Yes!

Now let me show you how this shuttle bus can see.

So, as we found out earlier, when people drive,

they need to use their eyes to see where they're going

and to watch out for things they could bump into.

But vehicles that can drive by themselves

they don't have eyes like we do,

instead they have special sensors like this

that help them to see and work out where they are.

How do the sensors work, Nina?

Ooh, let's go back to the lab to find out.

All cars that can drive themselves have special sensors,

to sense what's around them.

Let's do one final experiment to see how they work.

The sensors on driverless cars

send out a special kind of light which our eyes can't see.

And when this light bumps into things -

like the car that was in front of us earlier -

something happens.

So let's find out what.

I just need to turn the lights down.

I've got here a mirror and a torch.

Now look.

What's happened to the light?

It bounced off the mirror, Nina.

That's right. And the special light from the sensors on driverless cars

bounces off things too -

like other cars, people, buildings - in fact, everything.

And the light bounces back to the sensor.

If something is close to the sensor, it bounces back quite quickly.

But if it's further way, it takes a bit longer.

And that's how the car measures how far away things are.

Let's do another experiment.

We're going to pretend that this ball

is the special light sent out by the sensors.

I want you guys to roll the special light down the road

and we'll see how long it takes to bounce back.

OK, Selma, why don't you go first, my dear?

And watching...

All the way back! All the way back!

Brilliant! The special light bounced back.

-But it wasn't very quick, was it?

-No, Nina.

-No.

OK, let's try it again.

This time we'll see what happens if we put something in its way.

So what happened?

It bounced back quicker.

Yes, the light didn't have as far to go

before it bounced off the obstacle. So it bounced back much quicker.

And this is just like the shuttle bus earlier.

When something was in its path,

the light bounced back to the sensor quicker

so it knew something was in its way and the shuttle bus stopped.

Some cars that are already on our roads

use sensors to spot when something's too close to them,

and they either stop or beep to warn the driver.

Well, that could stop a lot of accidents, Nina.

It could, Felix.

In fact, cars that drive themselves

could make driving much safer in the future.

# Nina And The Neurons! #

So your question was,

"what amazing things will we have in the future?"

And I think we've answered it.

-FELIX:

-We discovered that clever people

are making cars that can drive themselves.

The cars are controlled by a computer

that can do the different things that people do when they drive.

BELLE: The computer in the shuttle bus

could only drive along certain journeys it had memorised.

-LUKE:

-The computer senses where the vehicle is going

by using sensors that bounce special light off things around it

to measure how far away things are.

-BUD:

-If something is blocking the road ahead,

the computer will sense it and stop the wheels really quickly!

I hope that's answered your question.

-BOTH:

-Thanks, Nina. Bye.

You're welcome. Bye.
