The Ugly Truth

Anyone completed this level yet?

Not much luck so far - my yellow bot gets zapped right on opening! ... So I'm exploring the theory that i can solve it without him. But as I say, no luck so far. Update: okay, so if i accept the ugly truth of an early death for the yellow bot, i also run out of influence very soon on the red bots. In fact there's only one that i can get anywhere, and even that ends in a useless loop up at the top. A checkmark confirming solvability would be very encouraging at this point!

Huhu. Seems the ugly truth still not prevail yet. Lets wait for the others and see if anyone could chew the truth ugly-ly.

if anyone have succesfully win this level, do share the hint as ambiguous as possible please.

Done twice and still not knowing how. A hidden red R appeared up the stairs and arrive to the objective. Trying again to check if I am able to reproduce how to free the hidden red R. Weird!
