Hold Up 4

Very nice puzzle. Quite liked how B is required below and how he gets down while still be able to get up. I first discovered another way to go down

Spoiler

stand on ball and let it drop

and somehow kept doing that for the second descend.

Other than that, I did it as in the movie, except I didn't re-guide R to the right to give B more time. There was plenty of time without it.

@Block builder - Good way to get down didn't think of that one especially when there was a working lift right there. Your way was fast - thanks

Got into a bit of a fankle with this level. Ended up just using one top ball as didnt need the other one.

Spoiler: One ball solution

like BB , i used the ball to get B down, then i herded pbot onto flight of stairs, then i got B to release the two lower balls one at a time. Then got on top of pbot and finished as movie.

@ridgerunner - Nicely done - I needed another stone pillar and you were very skillful to get that ball by the zapper with B. Thanks

@gmacpro ...no skill involved. Just approached head on , no problem. Repeated the move and again, no problem. Must compliment you on the ball/draggable/wedge set up. Led to interesting moves especially with the autopilot that i could not get to work initially. Was not pulling quickly enough and the slighest touch of B against the platform seemed to cancel it.
