Robshaw and co have lost their last two Championship clashes with Wales but on the last ten occasions that England have been going for the Triple Crown at Twickenham, they have been successful.
The last time the sides met at Twickenham Wales prevailed 19-12 thanks to Scott Williams' late try but 12 months ago in Cardiff, Wales romped to a 30-3 victory.
That was England's heaviest defeat in 124 matches with Wales - both sides have 56 wins with 12 draws - but Robshaw, who leads a side with just one change following Ben Morgan's introduction, is convinced that after seeing off Ireland at Twickenham last time out, Wales will be next.
"I'd say England. We're back here at home. Both sides are very evenly matched and very exciting but you've got to back yourself," said Robshaw.
"Last year doesn't have too big an influence. Look at what is up for grabs for us on Sunday - a Triple Crown. That's massive.
"Every time we're at Twickenham it doesn't matter who we're playing against we want this to be a hard place to come and play.
"People talk about fortresses and this is what we want it to be. It's not something that easily happens and it's a lot of hard work and dedication and it takes a lot of time but we have the opportunity now.
"It will be a slow building process but we need to make sure that every time we're out here our performance lifts by 20 per cent."
