Implementation

Assemble a robot scheme consisting of actions:
Create a variable with type logical "Logical variable 3" to record the result of the "Disjunction" action into it.
Move the "Disjunction" action to the workspace and set its parameters.
Move the "If" action to the workspace and set the action parameter to "Logical variable 3".
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.
Start the robot using the "Start" button and the top panel.
