Evade with Unity

Spoiler: Trick List

- low ceiling (B acts strangely with a low ceiling and may travel over blocks that B can't normally do)
- cancel tap (tap some place on the level where B can't go to stop the move)
- auto pilot (tap and move slider to redirect B)
- elevated zapper (an elevated zapper will change the properties of the block above to passable)
- squat drop (when B is pushed downward, B can get off at a lower level)

Spoiler: Video Solution

Lots of small differences but the overall gameplay the same. A few less moves at about 3 minutes as i simply used Z to get R down and across to the step. Then i left Z up there.

@ridgerunner - Yes - there are a few other ways too - even a nice low ceiling auto pilot to dislodge the mechanism. Thanks for P, C and R.

if it's a big map then I'll give up. because it is too difficult for R to be stable. the reason is that Z is not in the right position when picking up R.
thanks to the video

mini map but many challanging

I also had some differences but using the same tricks & without doing strange things so everything is ok. Very fun tricky gameplay. Thanks @Meko Guy
