• Did you copy the file from unit 2?
• Did you modify it (you should not)?
• Did you assign execute permission (chmod +x)?

Here it works out of the box. You should see some messages on the terminal, and the robot should make a square movement.

I suggest you carefully review units 1 and 2 and ensure that everything is properly copied.
