>> Mr. Bosley: Well, welcome everybody.
This is robots for work and play.
With these Lego robots.
I am Mr. Bosley and this is Ms. Conrad.
So, we are going to start off the day
by defining what is a robot.
There are four properties of a robot, first of which,
it is an autonomous system.
This just means it acts independently.
So for a robot, once you press go, the robot does what
it is supposed to do.
The next property we have is that it is controlled
by a computer.
This is like our bodies are controlled by our brains.
I brains tell our bodies what to do.
They tell our muscles what to do.
And a robot is controlled by a brain which tells it what to do.
A robot can also sense its surroundings.
As you see here, they have multiple sensors that you can
attach to robots.
And they detect different things much like we have senses.
We can see, we can taste, we can hear, we can touch.
And robots also act to achieve goals like our muscles do.
They have purpose, the do something.
So, a computer that does nothing is not a robot.
It has to be able to do something.
Let's go computer.
So, let's see what we think.
Is this a robot?
Okay, does it have a computer, does have motors,
does it do something?
>> audience: Yes.
>> Mr. Bosley: Does it do something by itself though?
>> audience: No.
>> Mr. Bosley: This is not a robot
because it does not do something by itself.
You have to control it by human.
So once you press go, it doesn't do it,
you have to control where it goes and where it turns.
How about this one?
Is this a robot?
>> audience: No, yes.
>> Mr. Bosley: What do you think?
Once you start it, does it just keep going?
>> audience: Yes.
>> Mr. Bosley: Okay, does it have a computer?
No, this one doesn't have a computer.
So this is not a robot.
What do we think about this washing machine here?
It is kind of high tech.
Okay, does it have a computer?
>> audience: No, yes.
>> Mr. Bosley: Alright, there is a chip inside
there that tells it when it is going to the next cycle
and everything.
Does it have sensors?
>> audience: Yes.
>> Mr. Bosley: It can tell when the load
is off balance or when the clothes are dry.
Does it act to achieve a goal?
>> audience: Yes.
>> Mr. Bosley: What does it do?
It washes your clothes.
It makes it so that we are not smelly.
And can it sense its surroundings?
We went through this right.
So, it can sense when clothes are wet and dry.
We have robots to do things that we don't want to do.
Sometimes things are dangerous or they are dull.
They are boring.
We don't want to do them or they are dirty and we don't
want to get smelly.
Question?
>> male speaker: [unclear dialogue].
>> Mr. Bosley: Yep, some robots can go
underwater for a lot longer than we can.
Very good.
So, for dangerous jobs such as space exploration where don't
know what is going to happen, we send robots instead of humans
so we can keep people safe.
For dirty jobs like cleaning sewers,
I don't think any of us want to do that.
So we have robots that can do that for us.
And factory work, things that you do over and over and over,
that is not very much fun, so we have robots that can
do that for us.
So some examples of robots, in space exploration,
we have the Mars rover.
It has sensors, it can see, it can send messages back to Earth.
It's got motors, it moves around.
Yes.
>> male speaker: A person goes up there
because it's too close to the sun.
>> Mr. Bosley: Yeah, it is a very dangerous
environment on Mars.
Yeah?
>> female speaker: Also, doesn't it have
certain storms?
>> Mr. Bosley: Yep, there is all sorts of
crazy weather and you can't breathe on Mars and there are
different pressures than on Earth, so we have robots
to that for us.
>> female speaker: I was just thinking about
that robot.
>> Mr. Bosley: Yes, good, yes.
>> male speaker: And a robot puts that on Mars.
>> Mr. Bosley: It takes a robot to get
the robot to Mars, very good.
We also have medical assisting robots.
These help doctors be really precise so they
make no mistakes.
This robot here puts little cameras inside of a patient
and makes a 3D image so the doctor can move machines
very slightly to perform precise surgeries.
We also have a industry.
We have welding robots.
This is a dangerous job.
It's hot and there is metals and all sorts of hazards.
So we have robots that can do it and keep people safe.
Do any of you have a Roomba?
You do?
[unclear audio].
This is a little robot that when you press start, it goes around
your house and vacuums for you because vacuuming is dull.
And this is a health care companionship robot.
It's called the Wakamaru.
It is from Japan.
They are very expensive but they provide assistance for
elderly people, they can keep them company and monitor them.
Remind them to take medication and call for help.
They're connected to the internet.
So they can be a good resource too.
They are quite expensive.
And in entertainment, we all know robots, right.
C-3PO, R2-D2, and we have WALL-E too.
So, these are a big part of our entertainment industry also.
Can you think of any other robots.
What do you think?
>> male speaker: R2-D2.
>> Mr. Bosley: R2-D2, yep.
How about you?
>> female speaker: Washing machine.
Stove.
>> Mr. Bosley: Washing machine,
some stoves might be, yeah.
>> male speaker: There is this robot in a book.
It is kind of like the Wakamaru and this one cleans up.
>> Mr. Bosley: Oh, that's nice.
We don't want to do that.
What other robots do we know?
>> male speaker: WALL-E.
>> Mr. Bosley: WALL-E, yep.
Okay.
>> female speaker: I'm not sure if this is exactly
a robot but at the bowling when the thing goes "sch."
>> Mr. Bosley: That's true,
that would be a robot.
That is a robot, good idea.
Yeah.
>> male speaker: The robot that goes into varies
of water that we can't because it is harsh.
>> Mr. Bosley: Yeah, robots to do exploring.
>> male speaker: Mystical creatures,
they're robots.
>> Mr. Bosley: Maybe in some movies,
futuristic movies.
One more, what do you think.
>> female speaker: Mars rover Spirit.
>> Mr. Bosley: Yes, other space ones.
Okay.
Well, there is another type of robot made by Lego.
It is called the Mindstorm's robot and we have some
of them here to test out.
Now there are different features.
This is the brain, the computer that tells it what to do,
and then you can attach motors, and this one doesn't have it
but we can also attach sensors.
The sensors that we can attach are the ultrasonic sensor.
This is like we can see distance, so can this sensor.
And we also have a light sensor, we can tell how bright a light
is, so if it is not very bright it can tell, but if it is super
bright, it can tell that also.
This one, this is our touch sensor like we feel things when
we touch things, so does this sensor.
And finally a sound sensor so it can tell how loud
or how quiet you are, yes?
>> male speaker: Is a robot faster
and some are not [unclear audio] and one of the things
you have to do is you had to add [unclear audio].
>> Mr. Bosley: Very nice.
We have some very similar to that.
Go ahead.
>> male speaker: I'm a Lego collector
and I used to have one of those but it broke.
>> Mr. Bosley: Oh, that's a bummer.
These are fun to play with.
Can you think of any other sensors that robots might have
besides the four that we looked at?
What do you think?
>> male speaker: The one that can detect like
the pressure in the atmosphere.
>> Mr. Bosley: Yep, we can check pressures.
What do you think.
>> female speaker: Where it senses how many rolls
or steps to do.
>> Mr. Bosley: Yep, we can tell it numbers and quantities.
>> female speaker: [unclear audio].
>> Mr. Bosley: They can detect different
substances in the air kind of like we can smell.
Okay, what do you think?
>> male speaker: Like how tough the terrain is,
like if it is safe to go across like ice.
>> Mr. Bosley: Yeah, we could have robots
to help us figure that out.
What do you think?
>> male speaker: A smell sensor.
>> Mr. Bosley: A smell sensor.
Yep, we could do something like that.
And one more, what do you think?
>> female speaker: Water pressure?
>> Mr. Bosley: We can detect pressures
or temperatures we could do too.
So we are going to have some stations now that we can explore
with these robots.
We are going to have five different ones.
One of them is a ball batter.
It is kind of like a baseball player.
When the ball comes it is going to...oh cool.
[unclear audio].
>> male speaker: Me and my partner
and somebody else, we did that.
One would roll the ball, the other one would smack it.
>> Mr. Bosley: That is what we got.
So you should be an expert with that one.
We also have a bumper car where it is going to drive until
it runs into a wall or somebody and then it will back up
and turn around and keep going.
We also have a robot that is going to follow a line between
a white paper and the blue tape.
>> male speaker: Can we make the line go
all the way around building and back.
>> Mr. Bosley: I don't know if we have
enough tape for that.
>> male speaker: What is fortune teller?
>> Mr. Bosley: The fortune teller one is you
ask it a question and then you press a button
and it will give you an answer.
And we also have a don't hit the wall one where instead
of bumping into the wall, it is going to tell how far
the wall is and stop before it hits the wall.
Go ahead.
>> male speaker: Can I go first?
>> Mr. Bosley: Well, we are going to have
stations that we are going to split up
and everyone can go to whichever station they like
and we can rotate.
Yes?
>> male speaker: That was one of the challenges
the first time through, there was a bunch of
big boxes that [unclear audio].
>> Mr. Bosley: Yeah, okay, what we will do is
we are going to close the door here and we will have
the bumper car robot over in the corner here.
Can I close this?
Thank you.
>> female speaker: Where do you want this one?
>> Mr. Bosley: Which one is it?
>> female speaker: Don't hit the wall I think.
>> Mr. Bosley: We can put that, you want to go
in that corner and move a couple desks.
>> male speaker: Will I be able to tape those or something?
>> Mr. Bosley: We've got a little tape, thanks.
We are going to have the baseball batter.
I am going to set that on the desk back here.
[musical noise].
[unclear audio].
Okay, that is fine.
And the fortune teller robot will be in the very back corner
over by you sir.
This one doesn't move, it can hang out by you again.
Just so it wasn't boring.
And then myself and Ms. Conrad will be here to answer questions
for you and we can show you on these computers some
of the programs and how you would program them, yes?
>> male speaker: How did you get these?
>> Mr. Bosley: These are property of the university here.
They own them, so they were nice enough to let us play with them.
>> female speaker: What's this robot for?
>> Mr. Bosley: That robot is the
don't hit the wall robot.
So it is going to stop before the wall.
So, we can split up into stations.
Oh, question real fast, do you have a question?
>> female speaker: No, I was going to say
my brother has a robotics kit.
He has a crocodile one.
Whenever it senses a stuffed animal, it will bite down.
>> Mr. Bosley: Cool, you can make these
do all sorts of neats things and build them all
into all sorts of shapes also.
So we have the ball batter back there, the fortune teller in
the other corner, the bumper car up here.
Up on the floor over here we have the don't hit the wall
and then our final station is up on the table here.
So you guys can split up into stations
and we'll go through these.
You can take these off.
Just turn off the monitor.
>> male speaker: Where's the don't hit
the wall robot?
>> Mr. Bosley: Don't hit the wall is over here.
I'll be right there for you guys.
[unclear audio].
Alright guys.
This one, once we start it, it is going to follow the edge of
the line here.
[unclear audio].
Our wheels are a little crooked.
Let me get these guys started.
Excuse me.
Let me see here.
Okay.
[unclear audio].
Excuse me.
There we go.
So now ask it a question and then press the button and you
will get an answer.
Have they got it going?
Is it not working?
[unclear audio].
Let me double check everything here.
Uh oh.
[unclear audio].
>> male speaker: How much does it cost?
>> Mr. Bosley: I think they're around $200.
They are pretty expensive here.
This guy wants to turn left.
Does he see the blade?
[unclear audio].
These are fun to play with.
[unclear audio].
Ah, here we go.
[unclear audio].
Here we go.
[unclear audio].
He should be staying on the blue line.
Let's try putting another on here.
This one, it is going to stop.
When it sees this line, it is going to stop.
Whoa.
It did.
So these things are never perfect.
That's interesting.
[unclear audio].
Excuse me sir, let me swing through here.
So what this robot does, you can click and drag all of these
things here and it's easy.
You just do step by step of what you want the robot to do.
So first, it's going to move the arm back like
when we started the program.
So it gets ready and then it is going to
wait until it sees the ball.
Then when it sees the ball it is going to swing the bat really
fast and then bring it back really slowly then
and then wait for a second.
And then we have it.
This is a loop here so then it does it over and over.
So then it is going to wait again until it sees it.
So, amd there is all sorts of things you can do with these.
Separately, I don't know how much they would be.
I think they are between $150 and $200.
>> male speaker: I have a question.
How much do you think one of these would cost?
>> Mr. Bosley: I think they are like
$150 or $200.
But there is a lot of stuff you can do with them and they come
with a lot of stuff.
So it is like a big kit.
You can make all sorts of ones.
They're fun aren't they.
[unclear audio].
That's awesome.
If you want, you can just grab the program for that
if they ask.
I might do that with these guys.
[unclear audio].
Excuse me.
[unclear audio].
You have a set of these?
>> male speaker: Except I can't find anything new
to do with.
>> Mr. Bosley: There is all sorts of things
you can find online.
So what this one is doing here.
Very nice.
[unclear audio].
So what this one is doing is its sensor is deciding,
oh can't see that desk.
Its sensor is deciding how far things are and if it's farther
than eleven inches here, then it is going to move straight
forever until it sees something but when it sees something that
is closer than eleven inches, first it is going to stop here,
then it is going to say whoa, or watch out
and it will display that on, oops, can't see that desk.
And it is going to back up like it does and spin around finally.
>> male speaker: I think it should be a 90 degree turn then
it doesn't keep going in the opposite direction.
>> Mr Bosley. Yeah, that makes sense.
>> male speaker: Can you change the program?
>> Mr. Bosley: Oh yeah, you can change it
to do.
>> male speaker: Yeah, you can do it online.
>> male speaker: No, I meant right now.
>> Mr. Bosley: We have a computer over here.
So do you want it to spin more or spin less?
>> male speaker: Spin more.
>> Mr. Bosley: So if we wanted it to spin more,
we'll go to this block here.
This is our spinning block and right now we have one rotation.
So you want to do more.
So we'll do three rotations.
>> male speaker: Does it change it automatically?
>> Mr. Bosley: Oh, thank you.
It doesn't change it automatically.
We've got to plug it in here.
But it only takes a second.
And we just upload it to our robot.
>> male speaker: I think the brain probably
costs the most.
>> male speaker: It's only a 32-bit
micro processor, not too large.
>> male speaker: But then it has to
connect to Lego, then you have to build it.
It's probably robots build robots which is weird.
>> Mr. Bosley: And it helps when we plug it in.
>> male speaker: That's a good idea.
I wonder what robots feel like when they are building robots?
>> Mr. Bosley: That's one thing that
robots don't have is feelings except in some movies right?
>> male speaker: Those AI intelligence,
artificial intelligence will just learn on their own.
>> Mr. Bosley: So now let's try this out.
It should spin more now.
[unclear audio].
There you go.
It never sees the little bottom of the desk there.
Yeah, it doesn't like the desks.
We're not in a good spot here.
Yeah, it sends out sound and then it gets it back.
A boy?
Excuse me, let me trade spots with you here.
[unclear audio].
How this one works?
Have you seen a magic eight ball?
Shake it up and ask it a question.
>> female speaker: I hate those, because
you always have to jiggle it even more for it to think.
[unclear audio].
>> Mr. Bosley: So what this does,
it's kind of like a magic eight ball.
It picks a random number and then the random number it picks
corresponds to one of the things it says.
So when you ask it, it randomly picks a number which then
the robot transforms that number into words.
>> female speaker: So how come when we
ask the same question, he says a different answer,
is it because of our tone of voice?
>> Mr. Bosley: No, that's just because it
picks a random number each time so he doesn't actually know.
But he'll tell you something different each time.
[unclear audio].
We have like five more minutes.
It's kind of a free-for-all.
[unclear audio].
He only stops when he gets bumped.
>> male speaker: Sir, what would happen
if you put that robot by that robot?
>> Mr. Bosley: Well, that one would probably
bump into him and he would probably try to stay away.
[unclear audio].
>> male speaker: Can I change
crawl the line robot into something else?
>> Mr. Bosley: Yeah, let's see what we
can change it into.
[unclear audio].
>> male speaker: What is this one?
>> Mr. Bosley: Let's see here.
We are going to try to make it work.
It's not liking the lines that we picked.
So we are going to try this guy again.
>> male speaker: I wonder what 50 rotations
would do.
>> Mr. Bosley: He would go for awhile.
So then we just plug him in.
What I did here is it's just going to decide how bright
it is whether it is the brightness of the white
or the brightness of the blue.
And then based on that it is either going to turn
a little bit back this way or a little bit back that way
so it follows the line.
[unclear audio].
Yep, you build them.
It just comes with a brick and a whole bunch of pieces and then
you can build them into all sorts of shapes.
Like this is kind of a standard one that you can do a lot of
different things with but you can also do the baseball batter
in the back.
You can build, they have all sorts of animals.
I think we have a faulty part.
Let me slow him down here.
He's going a little too fast.
And this is how fast he goes, like how much power.
So we can bring that down.
Let's see if we can make it a little slower.
>> male speaker: Okay, so then once you change it,
you have to plug him in so it can get.
>> Mr. Bosley: Yeah, we have to download it really quick.
I think they have real fancy ones that have...there we go.
Now he's following mine finally.
He's going to run into stuff though.
We need to get a bumper on him too.
Now he is following the line.
The blue has to be on the left.
These, you can buy them on the internet and some Lego stores
and some real fancy toy stores.
I know there are a couple of places in Champaign
you can buy them.
They are a lot of fun and you can do all sorts of stuff
with them.
And there is even advanced stuff we can do like...we can make it
decide whether yes or no or we can have it do math operations.
So there is one that we did, you can make it depending on how far
from something it is, if it's real far away, it will go real
fast but as it gets closer, it will slow down.
So, you make them pick a random number.
The fortune teller back there.
It takes a random number and then that number, it translates
it into text and displays it up there so it just picks
what it is doing.
Then from there, the computer inside of it is making that text
that you see.
[unclear audio].
