alien puzzle

It seems to me that this is a timing level more than a puzzle.
It seems to me that I went shorter than you planned because I did not use one bot.
I like the basic idea - the R(L) bot can climb a headless bot, but it can't climb down onto the grass! Therefore, you need to think about how you can get around this. I liked the solution of this main task (in my opinion, it is possible to make a more reliable stable ending). Thanks - great idea.

Spoiler: My VS

I won like @Denis Nazin but this time offset is a problem. Liked the last move. I think why B gets zapped even at ground level is that B is small. Thanks @Ian fawknotson
