On December 14, 2007, a crane's nylon sling, carrying seven tons of steel beams, broke and fell 25 stories onto a construction trailer at the site of the new Goldman Sachs headquarters. Inside the trailer was Robert Woo, a Canadian architect, and he was nearly killed by the crash and doctors said he might not walk again. But recently Woo has been walking, thanks to the Ekso bionic exoskeleton: CityRoom visited Woo at Mount Sinai Medical Center and took video.

Woo says that his three sons, who live in Canada with his wife, think that daddy is like a robot—or a "Transformer." The Ekso bionic exoskeleton is not for home use (yet; a version may be ready in 2013) and Mount Sinai is considering buying the $100,000 model Woo tried out for the rehabilitation department. City Room describes how the apparatus needs a human touch: There's a "hand-held controller operated by a physical therapist, 15 sensors, a small computer, 2 lithium batteries strapped to Mr. Woo’s back and 2 purring motors, resembling holstered shotguns, at his sides." Ekso wants to develop a model that fit under patients' pants.

Woo, who had been designing a new house in Toronto, "with elevators and upward slopes, but no stairs," sued Goldman Sachs and settled (he wouldn't discuss the terms).
