Blues face Barnsley at Leamington FC in the Fourth Round (7pm).
The premier knock-out competition for Under-18s carries a special cachet.
The run Blues made to the Semi-Finals two years ago created some memorable moments.
But it's about handling everything that goes with the Cup - and producing your best football.
Blues defeat of Sunderland in the previous round saw an impressive, controlled performance by the side.
Last year Blues fell at the first hurdle, with a disappointing reverse at Watford when much was expected of them.
"Sunderland was a great experience, especially for the young boys," said Robinson. "It was their first taste of the FA Youth Cup and the nerves, the excitement and everything that goes with the competition.
"The long journey up there, the expectation, the pitch they're playing on.
"You have to block all of it out and focus on what you are doing as a team, individuals.
"I thought all in all they handled it very well, it was an excellent night and we could have scored more goals.
"Barnsley will be a totally different game. We have played them already in the league and know what to expect.
"They are very workmanlike and in your face, very aggressive. So our boys will have to match that and then hopefully we will have enough quality that will tell.
"Yes the FA Youth Cup is a fantastic competition and of course you want to go far. But you cannot try to look at is as something special, really, you have to concentrate on every game, every round, and do what you have to do normally."
Blues are able to welcome Nick Kinina back into the squad after injury, as well as Oumar Traore. Both made their comebacks in the 2-2 draw at Hull City in the PDL on Saturday.
Kade Craig remains sidelined and Josh Dugmore has been waylaid with a knee injury. Charlie Noakes has resumed training again after an ankle issue.
Robinson has a selection dilemma, something which he welcomes.
"We always give everyone the best possible chance to be involved in it, and that's how it should be.
"The team that started in the Third Round, who knows?
"A lot of players have done well l in the games leading up to this one.
"Everyone is on their toes. We are in a good vein of form and health. I like the competition, the feeling that everyone is out there trying to earn the shirt.
"It's a tough selection to make but they have got to understand it's a learning curve. This will happen further on in their careers.
"They will get ups and downs when managers have to make tough decisions.
"I will always talk to them and make sure they are in the right place and get behind their teammates, which I know they will."
Admission is £4 adults and £2 concessions.
The winner of tonight's tie faces Wigan Athletic, away, in the Fifth Road.
