Man Climbs Chicago Tower Using Mind-Controlled Prosthetic
1 of 8
Zac Vawter, fitted with an experimental "bionic" leg, looks down from the Ledge of the Willis Tower, in Chicago. Vawter climbed 103 flights of stairs to the top of the tower using a new prosthesis that he controls with his mind.
Vawter kicks a soccer ball with a "bionic" leg as biomedical student Aaron Young makes adjustments at the Rehabilitation Institute of Chicago. After losing his leg in a motorcycle accident, the 31-year-old software engineer signed up to become a research subject, helping test a prosthetic leg that's controlled by his thoughts.
