Talking to the club website though before the squad set off for Italy, he wasn't going to be drawn on which position he wanted to focus on!
(Laughs) "It's scrum half at the minute and I've played there throughout the age groups but I'd never write off playing at 10."
"Look at French half backs like Elissalde and Michalak. They're really comfortable in either position and interchange without any hesitation."
"So, I wouldn't write it off completely and I guess it means that I can bring something different to a squad."
"It also helps me to have a wider understanding of the game. If I'm at scrum half, then I have an understanding for example of how my fly half might want the ball or what support lines are needed. It's valuable for game understanding."
England come into the tournament in good spirits having won the U20s Six Nations Grand Slam and face Ireland and Scotland once again in the pool stages something Robson knows is a real confidence booster.
"To know that you're the best side in the northern hemisphere is a massive positive especially when you've got two of the teams you've beaten the in Six Nations in your group."
"We've won the Six Nations which is great, but it's history. Now it's all about the Junior World Cup and the first game against Ireland."
"We have a look at the games they've had and their styles of play but we tend to focus on our own stuff and concentrate on our own game."
"We analyse our own game so everyone's confident in what they're doing and knows their role going into a game."
"Also you might look back on a recent meeting, like a Six Nations fixture and then find that half their side has changed. It's a different tournament and almost knockout rugby in a way."
Also lying in wait in the pool stages are South Africa, an opponent who defeated Robson and his England U18 colleagues last summer.
"A few of us suffered that defeat against South Africa in the 18s last year so it's good that they're in our group. I'm particularly looking forward to that one and I know a few of the lads will be raring to go."
"Having one of the Southern Hemisphere teams could help us massively with our progression. It'll be interesting as they play a similar game to us. They like quick ball and to move it around."
The tournament is a unique one for players of this age who have spent their careers to date alternating between club and country set up and Robson admits that it's a challenge but a welcome one.
"It's difficult to explain because it's so different to anything you might have done before. Three weeks way, playing a high intensity game every four days."
"You're representing your country and it's virtually knockout rugby. It's intense but it helps that we're such a tight unit."
"It's great though because you're involved in every session. When we're back at Gloucester, we may have to sit out a few plays in training because the coaches need to look at someone or something else."
"But, when we're here, we know that we're either going to be playing or have to be prepared to play. We have to be ready to go and be part of the team."
"It's a great stepping stone. Just look at the Gloucester boys like Charlie and Freddie and Trinder etc who have played in the tournament in recent years. They're getting loads of first team action now and making the Saxons etc."
Progression of course is key and Gloucester will miss several first team regulars in the autumn which will offer possibilities for the likes of Robson and Ryan Mills, a fact the Stoke on Trent born scrum half readily acknowledges.
"The next six months are massive. Following the World Cup, we've got a really important preseason and hopefully get a bit of game time in the preseason games."
"With Rory probably going to the World Cup, there could well be first team opportunities which will be great and that can only be beneficial when the 20s meet up again next year."
