And while it is the Quins backline that has received an array of positive column inches so far this term, Robson knows the foundations for success this Friday will need to be laid up front.
"We're looking forward to setting a physical marker down on our own patch," said Robson, who has featured in four of his side's European games this season.
"Wasps have got some good quality players and they definitely base their game around physicality. That's something we're more than aware of and we're looking forward to the challenge.
"We've got to make sure our scrum is improved this week. Our lineout's been going well and we've got to carry that on. We had 100 per cent last weekend on our ball and we've got to keep that up.
"With the backline that we've got, if we can win that physical battle up front it will stand us in decent stead."
Robson and co certainly won that battle when they hammered in-form Gloucester 53-15 a fortnight ago as they gave their exciting young backline plenty of opportunities to turn on the style.
And with the sun currently shining in the English capital and conditions seemingly improving every day, Robson is expecting another open encounter against their bitter London rivals.
"The ground is hardening up a bit and hopefully we can play a bit more rugby. That's something we're looking forward to," added Robson.
"We thrive on these conditions - just as Wasps do in fairness - and hopefully we can make that show.
"When we played them in the Premiership at The Stoop it was a very open game. It was end-to-end stuff and it was one of the most tiring games I've been involved in this season. Hopefully, it'll be something similar this time around and we can come out on top again.
"The forwards know we need to provide good ball and provide ball on the front foot as well. We're working as a pack to make sure that, when we carry, we do it well, get over the gain line, get the offloads in and make sure we're interlinking well with the backs. There's no point us just getting in the way out in the backline, we've got to make sure we know what we're doing and we're in the right position."
While that impressive display against Gloucester may have shown exactly what Quins are capable of, it is their most recent encounter that is currently sticking in the minds at their Surrey Sports Park training base.
A narrow defeat to current English league leaders and European giants Leicester Tigers left a bitter taste in the mouth as Quins let a 10-0 lead slip from their grasp.
Director of rugby Conor O'Shea spoke highly of the level of performance against the Tigers but he admitted inaccuracies in attack cost them dear.
Robson concurs with that assessment, insisting that the best way to make up for that disappointment would be with a win against Wasps this weekend.
And the England Saxons star is refusing to read anything into the fact that Quins have won two and drawn one of their three fixtures against Wasps in 2010/11. For Robson, and for Quins, it is all about the here and now.
"Losing isn't the best way of going into the game but we want to make sure we put that right - we're still pretty upset about the result at the weekend. We want to put that behind us now and make sure we get a result on Friday night.
"We are always saying that you're only as good as your last game and in our last game we lost to Tigers.
"We know the results against Wasps and they know the results but that doesn't really count for anything come Friday night. They'll be keen as anything. It's knockout rugby and we've got to make sure we turn up.
"We've already blown one semi-final opportunity in the LV = Cup and we don't want to blow another one. There's definitely a lot of motivation there."
