We're on-site today with Robonaut 2 for live demonstrations. While his brother, R2B, is packed on the Discovery Shuttle at the Kennedy Space Center waiting for liftoff, R2A is at GM's Vehicle Engineering Center giving university and high school students the chance to experience the technology and ask both NASA and GM engineers detailed questions. In this video, Timothy, a 9th grader at West Bloomfield High School in Michigan, goes head-to-head with Robonaut 2 during a strength exercise. Check out how it turns out.
