Default “the robots enigma”

“THE ROBOTS ENIGMA” puzzle

The basis of this puzzle is Raymond’s Smullyan “Three gods puzzle” but with smaller amount of base data, making it more difficult – more difficult than “The hardest logic puzzle ever…” As you can see, there is an incentive – good luck!

"Three robots A, B, and C are called, in some order, True - (T), False (F) and Random (R). (T) is programmed to speaks truly, (F) – falsely, but whether (R) speaks truly or falsely is a completely random matter.
The robots can answer only YES or NO. Each robot is equipped with two small lamps - red and white. When robot responds – the red light lights up, but you do not know he said YES or NO. When there is no answer – lights up the white light.
Your task is to determine the identities of A, B, and C by asking no more than three questions; each question must be put to exactly one robot".

Omg!! I have been at this for like the past 2 hours. The main catch is that the robots dont answer YES or NO. They simply indicate that they know the answer. Lets hope I get the answer soon...
