Software engineer using mind-controlled prosthetic limb scales Chicago tower

Lofty achievement

Software engineer Zac Vawter, who lost his right leg in a motorcycle accident, yesterday climbed Chicago’s 103-story Willis Tower wearing what researchers are calling a breakthrough neural-controlled “bionic leg.” His climb was the technology’s public debut and part of a charity event called "SkyRise Chicago" hosted by the Rehabilitation Institute of Chicago, where Vawter receives treatment.
