A new pair of robotic legs out of New Zealand
lets wheelchair users do the improbable--stand, walk, and even go up and down stairs. Users transfer themselves from their chair into the Robotic Exoskeleton (Rex) by holding on to Rex's legs. They then strap themselves in and use a hand-controlled joystick and control pad to maneuver the battery-powered mobility-assist device on solid, stable surfaces such as those inside the home or workplace.
