4 Bots 6 Stars

Spoiler: Video solution

More bots, more job, more challenge so... More fun! thank you @Chris Hester

Ooopppsss, forgot the rating

I didn't use L bot and I capture the star(which is captured by L) by B. It's weird because R wouldn't want to step off B even though B's height is same level with the block.

I also didn’t use L

Nice tight tidy evel. Thanks @Chris Hester .

Wow! Even though the level is so small, it is very unique. 5 stars for you mate!

Nice elegant, original, compact, fun level.
