Hi @ghduarte

the possible reason why your script is failing is that what you are doing is:

- You are moving forward only when there are walls on both sides

But what you have to do is:

- Keep moving until there are no walls detected on both sides.

Your current script stops as soon as it passes the **robot’s left wall** , but the robot at this point has not yet gone through the **robot’s right wall**. Please check the expected behavior in the image below to understand what I mean here:
