Step 4 – Complete the Maze!

Add and Test 2 Blocks at a time

Now that we’ve gotten this far, all we need to do is repeat this pattern until we finish the maze!

And by “this pattern”, I mean the pattern of checking where we need to go next, then placing the next two blocks to complete this task. Let’s call this the two block rule.

This rule is very useful, because of it any time you mess up, you only need to change 1 or 2 blocks, instead of all of them!

You may need to edit the “200mm” value on some of the forward blocks, but the turns should always be 90 degrees.

If you complete the maze and want another challenge, see if you can get the robot to touch all the numbers/letters or both!
