About the Lesson
Problem of the Day 
Read the problem of the day. The problem of the day is "How can you make NAO ask you a question and listen for the answer?" You will discuss what it means with your teacher.
Sample Program 
Watch the sample program that your teacher shows you carefully. Then complete the Robot Story! activity on the next page. 

Robot Story

Listen to NAO tell his story then answer the questions on this page.

Now, draw a picture of your favorite ending on a piece of paper!

Your Story!

Fill out the questions below. You should write multiple endings to your story that are based on the response to a particular question. The responses do not have to be "yes" or "no",  but should be limited to one or two words each (i.e. “not blue” is OK, but “He should choose the one that is not blue” is not OK). 

Now add the two endings in to story.

ENDING 1

Draw the ending 1 on a piece of paper.

ENDING 2

Draw the ending 2 on a piece of  paper.

How will you switch between the two possible endings you’ve created? (There’s a hint in that sentence)

We know you will need:

1. Some way for Nao to recognize what you are saying
2. A conditional (based on what Nao hears you say) that determines the action she will take
3. Different code paths for Nao to take after each option

It may be helpful to think about it like a choose your own adventure book.

Page 1

You are sitting in a dimly lit tavern eating hot wings. A group of villagers approach you, looking frightened. “Help!” an old woman cries my poor kitty has been stolen by a werewolf!”

            To agree to help the villagers find the kitten, turn to page 5.

            To tell everyone to leave you alone, turn to page 8.

                        Page 5

The villagers tell you they saw the wolf flee into the dark forest at the edge of the village.

To run toward the forest, turn to page 11.

To go collect some supplies, turn to page 12.

To chaqnge your mind and return to the tavern, turn to page 14.

Page 11

You are standing on the edge of a dark forest. A wolf howls in the distance, and you feel a chill go down your spine. Could it be the werewolf?

To investigate the forest, turn to page 16.

To return to the general store for a flashlight, turn to page 20.

To walk back towards home, turn to page 21.

Seems pretty simple, right? But just like in real life, decisions build on each other, and the options you have for the second decision depends on the decision you made for the first!

As you write the rest of your story with Nao, you need a way to keep track of past decisions and help him respond in the correct way. How can we “choose our own adventure” with Nao? Using programming logic!

You have heard these two logical operators used in plain English:

AND – if X is true and Y is true, the result is true

OR – if X or Y (or both) is true, the result is true

These logical operators are a little strange

NAND – if X is true and Y is true, the result is false

NOR – if X is false and Y is false, the result is true

You can use this logic to make your own adventure with Nao more customizable.

Making a Choice!

You are going to have Nao ask where the characters should go in your story. Depending on your choice, Nao will change what he says. Here is how you program this in Choregraphe.


1. Ask The Question.
Drag out an animated say from the box library. Have Nao ask the question. Plan your question in the space below.

2. Listen For The Response.

Drag a Speech Reco box out from the box library. Read the reference to make Nao listen for the correct responses.

3. Change The Flow.

Drag out a Switch Case box from the box library. Connect it to the Speech Reco box as in the picture.
Type the same options from your Speech Reco box into your Switch Case box. Make sure to use quotation marks around each case!

REFLECT and REVISE!

Test your code on the real robot. Remember, the Speech Reco box will not work on the virtual robot. After testing, answer these questions.

Test your code on the real robot.

Silent Journaling 

Fill out the following questions. You should work silently for a few minutes.

Group Discussion 
After you have journaled, discuss your response with your group.
