# Creating a Solitary activity

Cannot be tested on a simulated robot.

This tutorial will show you how to create a Solitary Activity launched thanks to Trigger conditions.

Create the following solitary activity: when the robot does not detect anyone for 10 seconds, he says “Is anybody there? I feel lonely, hope someone will come soon!”.

## Step 1: Create a Behavior

Step | Action
--- | ---
| Create a new Project and save it as “my_first_solitary”.
| Right click and rename “behavior_1” folder into “iamlonely”.
| Drag and drop Speech > Creation > Animated Say box onto the Flow Diagram panel.
| Connect its input to the main input of the Behavior and its output to the main output of the Behavior.
| Double-click the Animated Say box and edit the Localized Text box content with:
    "Is anybody there? I feel lonely, hope someone will come soon!".

Test the Behavior

Step | Action
--- | ---
| Click the Turn autonomous life off button.
| Click the Play button.

Result

Your robot says the sentence.

## Step 2: Transform it into a Solitary Activity

Step | Action
--- | ---
| Edit the Project Properties.
| Set the Application description. For example, you could write:
    This application contains the following solitary activity: when the robot
    does not detect anyone for 10 seconds, he says
    "Is anybody there? I feel lonely, hope someone will come soon!".
| Copy the auto-generated Application ID, you will need it to write the Trigger conditions.
| In the Package content, select the Behavior “iamlonely” in order to display its properties.
- | Set: the Name with “I am lonely”, the Nature with “Solitary” and the Launch trigger condition with
      (('Launchpad/PeopleNotSeen' == 1) ~ 10) && ('Launchpad/PreviousActivity' !=
      "<my_application_id>/iamlonely")
Where <my_application_id> is the Application ID you have previously copied.

Test the solitary Activity

Step | Action
--- | ---
| Save the Project.
| In the Robot Applications panel, click the Package and install the current project to the robot button.
| Click the Turn autonomous life on button.
| Remain out of reach of your robot for 10 seconds.

Result

Your robot says the sentence only once, and will not repeat it until another Activity take place.

## Understanding the Trigger conditions

We want our solitary activity to be autonomously started when no person has been detected for 10 seconds. Thus we are using the event Launchpad/PeopleNotSeen and the trigger condition looks like this:

    ('Launchpad/PeopleNotSeen' == 1) ~ 10)

However as we do not want our application to be started continuously if there is none around the robot, we added another condition:

    ('Launchpad/PreviousActivity' != "solitaryactivitysample/iamlonely")

This Condition makes sure that the activity will be started only once in a row. The activity will be able to be focused again if another activity has been focused in the meantime.

Thus the final launch trigger condition of our activity becomes:

Expression part ... | Means ...
--- | ---
(‘Launchpad/PeopleNotSeen’ == 1) ~ 10) | no people is seen during 10 seconds,
&& | and
(‘Launchpad/PreviousActivity’ !=”<my_application_id>/iamlonely”) | the last activity was not “iamlonely”, i.e. another Activity took place since the last loneliness complain.
