Definitely interesting level, but there is a big shortcut: Spoiler By moving the topmost vertical slider up one space to be flush with the ground, the closest R bot will walk over it, down the stairs and back up all the way to the end button. That same slider also could benefit from having a pole to slide on so no bots could get stuck in its hole. Great start!
I have lots of fun with this level. But probably in another way the author thought? to me the challenge is the race to be first at the goal ;-) And to understand the logic of the red-ones walkings (is there any?) Nice level to fiddle around without stress. thank you!
