The Rex is a set of bionic legs hailing from a lab in New Zealand that may potentially replace wheelchairs in the future. Although the wheelchair will forever aid many handicaps and injured individuals, the fact that the Rex can simulate the motion of walking is undeniably beneficial and desirable.
Although you can see the Rex in action via the video above -- watch Hayden Allen use his legs for the first time in five years -- it is currently too expensive to put on the market at about $150,000 for a set.
