Robots help with daily tasks
Pictured here in March 2011, Robonaut 2 works out with Commander Scott Kelly aboard the International Space Station. Brandi Dean, the press officer for the Johnson Space Center, told Space.com, "We've never put a dexterous humanoid robot in space before. So we can make theories about how they'll behave in space, but it's always great to check them." Robonaut 2 was designed to help with risky experiments and mundane chores aboard the ISS.
Kelly is the brother of astronaut Mark Kelly, who is the husband of Arizona Rep. Gabrielle Giffords, who was critically wounded in an assassination attempt in January 2011. Commander Kelly was reunited with his sister-in-law at a Houston hospital after his return from space in March 2011.
