Why am I hearing Rick Astley singing when I open up this level page.

Obviously, the solution is splendid and rewarding.

i found the right way.but i have a problem with releasing spilar-bot

Finally!
Releasing P was a challenge but when I figured out that part everything else just fell in place.
Great puzzle.
Thanks!

What @cpw said

What a glorious level. Lots of nice problems. Stupidly used autopilot once when B could have walked from the long draggable. However i used a different method to get B ontop of R.

Spoiler: B onto R

I had R in the same spot below the wedge , but having got him there via the draggable, then i put B as far away as possible, raised and tapped the draggable then let R walk onto the draggable and lower it and B lands on top. I prefer your use of the wedge though.

What upset me is that I found 95% of the solution. But I did not really found the move of transfer of B top the R . Sometimes the simplest solutions are the most inaccessible and invisible ones

Nice logical level.

@cpw It's really amazing that @chemi did not say anything about this level until now

@chemi hasn't solved it yet, I think.

@cpw, here it is what @chemi says...

Wow! Finally finished. Amazing! It's a another jewel in logic puzzles. I got stuck for a long time trying to manage R bot. It was not complex but I didn't see the key idea until yesterday. Really enjoyed it. Thanks!!!

Excellent tricky/logic level!! Wow,your logic brain is full of brilliant ideas!! This was a difficult challenge!! But finally I've got it!! Nice blue!! Thanks for sharing and excellent job @Star Penguin

Nice path and quite strange i play your level without the ball

Wow, I had a tough time every step of the way for this one & needed the video for the final move. Sometimes it takes a special kind of eye to see

autopilot impossible paths.

One thing I can say to make myself feel a little better is that I figured out a more efficient way to do the first move with R.

Spoiler

R walks on B's head. In the video, B lets R fall. In my version, B carries R to the stair (not the draggable!) under the wedge. R dismounts from B and B can easily herd R up the next set of stairs.
