Implementation

Assemble a robot scheme consisting of actions:
Create a variable with the boolean type "Variable3" to record the result of the "Less than" action into it.
Move the "Less than" action to the workspace and set its parameters.
Move the "If" action to the workspace and set the action parameter to "Variable3".
In the "True" branch, add the "Show message" action and set its parameters.
In the "False" branch, add the "Show message" action and set its parameters.
Launch the robot using the "Start" button and the top panel.
