forced to fall

I almost gave up and asked for a hint as after 15 to 20 minutes, I had the balls down but the two Rs were still walking back and forth.

Spoiler

B was sliding the mechanism and after about 10 times, pillarR fell and then the game was on.

Thanks

Spoiler: New Trick

Was it the stairs climb over?

Good logic puzzle, and the new trick (to get R down I assume) posed a good thinking challenge.

@gmacpro
Thank you, my good friend. It's a bit hard to explain this trick. In one experiment, I realized that when B or R is passing through the block, if a part of the block is moved from the row of the blocks, B or R fall from the block. You can see this function in the video below:

dear @Block builder
I am glad that I finally made a level that was interesting to you. Your views are encouraging me. Thank you very much

Good logic level plus the player is led nicely into finding the trick as there is no alternative.
Having now looked at the video i see i didnt really use the trick properly. I moved the budgeable whilst R was on it , but i see that your video of the trick shows the budgeable being moved slightly beforehand, and that works better.

Nice logic level although the new trick is not really intuitive (congrats for the discovery). Thanks!

@gmacpro You are right it will new but I already use this trick in my level(Uncharted 1) this trick found by @PvB but my trick is little different my trick works automatically.And in this level the trick was pretty similar but manual.
Thanks.......

| Very interesting and new way to divert R bot's path. I did peek at the video for a hint but still, I spent more time adjusting the movable part. I'm glad that it could be adjusted in both ways, left and right. It's a bit frustrating if you don't know the trick but one must learn something new especially this 2018.

As @chemi said
