In this TED Talk, Eythor Bender of Berkeley Bionics is first introduced by Amanda Boxtel, a member of Berkeley Bionics test team, who begins by using her own story to prepare the audience by drawing them into the experience of being confined to a wheelchair. Bender briefly traces the history of mobility devices and Berkeley Bionics' development efforts, and then reintroduces Amanda, this time wearing an eLEGS exoskeleton, which makes it possible for her to walk. The rest of the test team is then brought on stage.
