The Vanderbilt leg is seen above worn by Craig Hutto, left, and Professor Michael Goldfarb, who is leading the team at VU. The leg itself has been in development for always seven years now, and packs in quite a bit of tech.
The device uses the latest advances in computer, sensor, electric motor and battery technology to give it bionic capabilities: It is the first prosthetic with powered knee and ankle joints that operate in unison. It comes equipped with sensors that monitor its user's motion. It has microprocessors programmed to use this data to predict what the person is trying to do and operate the device in ways that facilitate these movements.
