What is a robot? Machine
Built to do job(s) Programmed Maybe autonomous
If we want robots to do things for us, we have to program them
How do we program a robot? What does the robot need to KNOW
to do useful things?
How do robots work?
What do they need to do to perform tasks?
Imagine picking up some trash from the floor and taking it to the nearest garbage bin Need to get an understanding of what’s around
them, like where the trash is (SENSE) Need to work out what they are going to do,
and how they are going to do it (PLAN) Then they need to actually do it (ACT)
What does this have to do with computer science?Designing new robots
New sensors New ways of combining sensor
information New effectors
Making robots think How to get them to talk How to make their eyes work
All of this involves writing programs
So, what is computer science?Computer programming
Create the behavior you want the robot or computer to do
Think ‘algorithmically’ Write down that algorithm in a way that
a machine understands Test it, improve it
Acting: How do I do it?
How do we do things? We move around We pick things up We drop things
Robots need to use the sameCalled ACTING
Effectors (for Action)

Tasks (three different challenges) Move forward 3 seconds, then
backward 3 seconds Move forward 3 seconds, and turn
left or right (try to get close to a 90o turn)
Drive around a square
Is there a better way to do this? Let’s create a new program
Loops

Tasks(two different challenges) Use the loop structure to make your
robot drive around in a rough square
Can you make it so that the robot drives EXACTLY once around the square, and then stops?
Can you make it drive once around a square, and then rotate roughly 360 degrees on the spot?
Sensing: What’s going on? What do we use to find out about the
world around us? Eyes Ears Touch Taste Smell
Robots need to use the same Called SENSING

Create a new program (called avoidObjects): Drive forward IF there’s an object ‘close’ to the robot THEN turn 90 degrees left or right (your
choice) Do this forever
Avoid objects
Sensing
Create a new program (called avoidRedObjects): Make the robot drive around IF it detects something RED THEN stop
What have you been doing? You’ve been programming your robot Giving the PLANS or INSTRUCTIONS
to do tasks Using SENSORS to help make
decisions Using EFFECTORS to carry out those
plans
Planning: What should I do?How do we decide what to do?
Make decisions of what to do… …and when Put things together in sequence Make a plan (for the day, or week, or…) Have to be able to deal with things that
occur as we do our stuffRobots need to use the sameCalled PLANNING
Plan
Think of IF-THEN rules
IF <see garbage> THEN <pick-up> IF <holding garbage> AND <at trash
can> THEN <drop garbage> IF <10PM> OR <battery low> THEN
<sleep> IF NOT <holding garbage> THEN
<search room>
Definition of a social robot Social robots will interact with us in
our world Need to cooperate, communicate
and collaborate with humans Have to understand our goals, our
actions, and our behaviors What do robots need to achieve this?
Example: Roomba
Example: Roomba
BANG!!!
OUCH!!!!
Example: Roomba
BANG!!!Ooops. Sorry!
Example: Roomba
And then I said to her, you
know….
VRRROOOMMM
What the heck…hang
on…ROOMBA: NOT
NOW!!!And SHE said
that I was, and I said…
The reality…

So let’s make your robot social! Thinking about the AVOID program
from earlier What would a POLITE robot do?

Social Robot(challenges—pick one!) Create a POLITE robot and show it off Create a SHY robot and show it off Create a FRANTIC robot and show it
off Create a SILLY robot and show it off
