AUTorEPAIR

READ THIS BEFORE PLAYING THIS LEVEL.

Due to some inaccuracies in the position, if you let this game play itself long enough (like, 10 minutes), bots might eventually offset enough and get you the final star without even playing. This is not where you will enjoy it the most. Please solve it yourself

You might want to play the prequel Capture the Flag https://mekoramaforum.com/media/capture-the-flag.24356/#comment-150474
to get a sense of where the difficulty is (and it's not that complicated).

Now some hints unless you want to discover everything yourself:

Spoiler

Yes, if L escapes, the topmost R zapper will get the star. That's all the point. Every 12 moves it tries to escape, but there is a guard every time. Where does this guard come from? How to move the guard away, just once?

Spoiler

Try having B cut any of the two loops and enjoy the auto-repair mechanism that will prevent L from escaping.

Spoiler

I placed sand where you might want to move B to reach various destinations

Spoiler

Yes you'll need to sacrifice B, but on which of the two sands?

Spoiler

There are a lot of mechanisms to remove unwanted zapper bots, depending on where B falls when zapped. Hence, not everything is relevant for everyone.

Spoiler

Sacrificing B is not enough. You'll have to offset the lowest-level R bot wisely so that the zapper you deviate can cut the second loop.

Spoiler

If x and y are the two entries of the gate (x the big loop and y the small loop), the output of the gate is (x or y) - that's the central piece of fun - the new big loop is x, and the small loop is (x and y) or not x.

Spoiler

I just need to put B under the "stair" and L will go from above, so the top zapper can go to win block.

Oh sh**t I did not know about this shortcut.

@Meak - are you by chance an electrical engineer? Your levels are giving me flashbacks to my college days.
