Hayden Allen hasn't walked in five years, but in this video, he's able to move around using a new type of exoskeleton called REX:
Called REX, short for "robotic exoskeleton", the legs weigh 38 kg (84lb) and are individually made for each user.
The first pair is expected to sell for $150,000 (£97,600) the equivalent cost of 20 standard wheelchairs.
The inventors claim that due to the upright and mobile nature of their creation, users will not suffer the burns, scrapes and bladder infections that can come with wheelchair use.
One of the great features of this design, as you can see in the video, is that it's fairly easy for a wheelchair user to mount the exoskeleton by him/herself.
