This tutorial starts like the Using Dialog topic in Choregraphe tutorial, then goes deeper in masytering Dialog boxes and QiChat scripting.



CONTENT



Hello World

  • Start Choregraphe.
  • Drag the Speech > Speech Settings > Set Language box on the grey area.
  • Click the parameter button and set the language as English.

  • Right click the grey area and choose, in the contextual menu, Create a new Box > Dialog....

  • Click the Add a new topic button, then type a name without spaces, for example: HelloWorld.
  • Click the Add button, then the OK button.

  • Create links as below.

    

  • In the Project content, double click the HelloWorld_enu.top file.
  • The Script editor appears.

  • Type those rules:


u:(Hello) Hello, young Padawan

u:(Good morning) Let's start a wonderful day




Testing on a simulated robot


  • Make sure you are connected on a virtual robot.
  • Click the Play button.
  • In the Dialog panel, enter “Hello” and press Enter.
  • You can see the result both in Dialog panel and in the Robot view.




Testing on a real robot


  • Make sure you are connected on a real robot.
  • Click the Play button.
  • Wait for the signal indicating that the robot is listening:
    • A “bip” sound is played and
    • Eye LEDs become Blue and turn.
  • Say “Hello” :
    • The robot says “hello young padavan”.
    • You can also see the result both in Dialog panel and in the Robot view.




"Hi", "Hello"... in one rule

To make your first rule a little bit more complex, enrich your script:


u:([hi hello wassup]) hello young padawan

u:(["tell me" "give me"] your name) of course, my name is NAO





Connecting QiChat script and animations


  • Add these new rules:

u:(["can you" please] sit down {now}) ok i sit down $sit=1

u:(["can you" please] stand up {now}) ok i stand up $standup=1


    

  • Add two outputs to the Hello world box.
  • one called “sit”,
  • one called “standup”.

Note: here we use Bang type, an easy way to propagate an event.

  • Add two Programming > Time > Wait boxes and connect them to the outputs you have created. 
  • Add and connect a Movement > Posture > Sit Down and a Movement > Posture > Stand Up boxes.




Jumping from one topic to another


  • In a new Project, add an Speech > Speech Settings > Set Language box.
  • Create two different Dialog topic boxes, called Food and Sport with the following content:
topic: ~Food()
language: English 
u:(let's talk about food) OK, guess what I like 
u:^private(do you like fish) yes and sea food too
u:^private(do you like meat) no, I don't
topic: ~Sport()
language: English 
u:(let's talk about sport) OK, guess what sport I like 
u:^private(do you like tennis) no, I can't play tennis
u:^private(do you like yoga) yes, would you like to do yoga with me?
  • Link the tree boxes as follows:


  • Test it.
  • To jump from a topic to another and give it the focus, use the one of their user rules:
  • In our example : “Let’s talk about food” or “Let’s talk about sport”.
  • Once a topic (food or sport) has the focus:
    • all its private user rules are activated,
    • while the private user rules of the other topic are not.



Advanced tips

Sending QiChat variable through box output

Be aware: in QiChat, a variable has no defined type.

Workaround:

  • Use a Bang Output if you are just looking for sending a signal to another box.
  • Use a Dynamic Output, if you want to use the value of the variable in another box; then cast it into the type you want in your box script:
def onInput_dyn(self, p):
    try: 
       p = int(p)
    except ValueError:
       # If p is a string you may have an exception.
       pass
