aquarium trouble

This appears to be very difficult. I have almost won twice but my gameplay is tedious so i am giving up

Spoiler: My attempts

get ball below. Delayed autopilot to get B onto the ground then get B or an R to push the ball into winblock corner so B can autopilot onto the ball then step onto win.

I returned to the level and won. But the difficulty in seeing where the bots were and viewing the corner blocks to tap made my gameplay too awkward to be enjoyable.
