Slide 2

Form groups What does a robot mean to you? Report back to group

Slide 3

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?

Slide 4

Pick up the garbage and put it in the garbage can Give instructions to robot If it understands, it will carry out instructions If it does not understand, it will shake its head

Slide 5

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 whats 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 )

Slide 6

How do we do things? We move around We pick things up We drop things Robots need to use the same Called ACTING

Slide 7

Gripper Motor Legs Wheels Tracks Face Display Speech

Slide 8

Learn how to make your robot ACT SENSE Write programs to make it PLAN

Slide 25

Move forward 3 seconds, then backward 3 seconds Move forward 3 seconds, and turn left or right (try to get close to a 90 o turn) Try to get robot to drive around a square Is there a better way to do this? Lets create a new program

Slide 26

Slide 27

Slide 28

Slide 29

Slide 30

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?

Slide 31

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

Slide 32

Slide 42

Slide 43

Slide 44

Create a new program (called avoidObjects): Drive forward IF theres an object close to the robot THEN turn 90 degrees left or right (your choice) Do this forever Try a new program with the color sensor Make the robot drive around IF it detects something RED THEN stop

Slide 45

Slide 46

Youve 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

Slide 47

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 stuff Robots need to use the same Called PLANNING

Slide 48

Think of IF-THEN rules IF THEN IF AND THEN IF OR THEN IF NOT THEN

Slide 49

SENSE PLAN ACT Its an old idea Its still around Youll encounter this in any robotics class youll ever take

Slide 50

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? Which of our robots is most `social?

Slide 51

Slide 52

BANG!!!

Slide 53

OUCH!!!! BANG!!! Ooops. Sorry!

Slide 54

And then I said to her, you know. VRRROOOMMM What the heckhang on ROOMBA: NOT NOW!!! And SHE said that I was, and I said

Slide 55

Slide 56

Thinking about the AVOID program from earlier What would an ANGRY robot do? What would a POLITE robot do?

Slide 57

Slide 58

Slide 59

Slide 60

Slide 61

Create either an ANGRY or a POLITE robot and demonstrate it

Slide 62

Home help Pick up trash Cook dinner Tidy your room Go to the store Pet care Walk dog Feed dog Play games School assistant Hand out assignments Monitor the hallways Pick up books Sport robot Play soccer Play tennis Referee a match

Slide 63

Sensors Effectors Planning

Slide 64

45 minutes 5 groups Leaders are here to help Play around

Slide 65

5 minutes

Slide 66

Scenario Sensors Plan Action

Slide 67

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

Slide 68

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

Slide 69

Questions? What do you wish we had talked about? Evaluation so we can improve this workshop! 3 minutes!
