 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?

 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 )

 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

 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

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

 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?  Let’s create a new program

 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?

 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  Try a new program with the color sensor  Make the robot drive around  IF it detects something RED  THEN stop

 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

 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

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

 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?

BANG!!!

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

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…

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

 Create a POLITE robot and show it off
