The Harlequins openside will lead the team against Australia, Argentina and New Zealand after beating Tom Wood to a post he last held during this year's RBS 6 Nations.
"Every time you pull on that white shirt it's a privilege. It's a huge honour," Robshaw said. "But I've always said it's not about who you are but what you do, and I've got to make sure that I perform first. We have some good leaders across the squad and I know we will support each other as we head into a massive game against Australia."
The 27-year-old has led England in 16 of Lancaster's 19 games, missing only the final Test against South Africa in June 2012 and both matches against Argentina during last summer's tour. Overlooked by the British and Irish Lions, the 17-times capped openside was given the summer off by Lancaster.
Wood took over the captaincy and acquitted himself well but Robshaw has impressed in a struggling Harlequins team. "The criteria for captaincy is to be on the team sheet and Chris is in there on his playing ability," Lancaster said. "But on top of that he has a massive amount of respect within the squad."
