Third ball and R

Wow - really obscure so far.... How to get B back up after P is released?

EDIT - Cancel last - got it....

I had to drop 1 star due to the issues and instabilities that required SO many restarts. You'll want to know what they are so here goes:
- The P mechanism was slow but always worked however some times it was over 1 minute
- The zapper mechanism wasn't always so graceful. Some time it fell on top of the ball and other times short causing P to get unstable and walk off onto the surface.
- On my 1st release of R, R turned at the wedge and fell off the top onto the surface - I had no part in that instability?
- Other things, the requirement for two ToA without a rounded edge so B went back and forth way too many times and I wasn't pleased with the hiddenness - you know where I stand on that!
Aside from that, the level was LONG and complex and did take a while to know what you wanted us to do. The title seemed strange as you had 4 balls so I wondered if one wasn't required but I know differently now. BTW, to answer my question above about getting B back up... I hadn't seen the hidden part at that time so I used an auto pilot. On the lift for the 1st ball, tap the grass towards R and raise, B will be on the upper level again. Thanks - that was most of the morning playing your level.

Have awarded 5* for the lengthy and complex method i used, but it seems to bear little relation to the method used by @gmacpro . I have no idea what “zapper mechanism “ is , but presumably it is the other mechanism as i only used one-pillarbot release. I did not use any toa.

Spoiler: My way

released pbot then used him to release R then used B to release top ball. Fair bit of herding to get R and pbot on the metal half cylinders ball near winblock and used B to alter the timing of interaction between Rs to force the right turn to win. I didn’t use one of the balls..

Dear @gmacpro
thank you my good friend. I have always benefited from your correct and fair critique. I was sure that you at least try this level and declare your constructive comments impartially. Thank you again

Dear @ridgerunner
Thank you, even though I'm designing less than the past , but your good comments are my encouragement.

Here is my lengthy video tho i have just realised by placing B one square away i could have herded Pbot directly to the big draggable.

@ridgerunner
I'm really impressed with seeing your solution! I've been working hard to create a unique solution + , and it's the designer's solution. Of course, you've succeeded in using such an unusual method because I've put the sliders manually. " Those were initially automatic and the reason for this was a faster run-time.)

Aha!! Returned this morning and found the second mech. Annoyingly i had tried this very early on but I wasn’t expecting the ball to trigger a mech so I probably didn’t wait long enough. I now see the need for all the balls and nice use of R. So i think i have the full gameplay now and it is all very impressive. Bravo! It doesnt need any ToA so i would be interested to know if @gmacpro was solving it a third way.

@ridgerunner - I'll do a video up later (assuming all stays stable enough)...

@ridgerunner / @hadi - Here's my video

Spoiler: Video

I've even changed my rating to 5 as I was able to do it nice and stable, etc

@gmacpro .. my interpretation of the designed gameplay is a bit different especially the lowering of Pillarbot. I messed up the ending and am not going to record again.

Spoiler: Designed gameplay?

@ridgerunner - Looking pretty unstable at the end - I was expecting R to jump but I see what you meant.

@gmacpro and @ridgerunner My good friends, thank you for trying to provide different solutions. Your analysis of this level and your description is worth more than hundreds of comments for me.
