Two New Zealand inventors have produced what they claim are the world's first robotic legs to help paraplegics walk again.
The bionic legs were road-tested publicly for the first time Thursday by 23-year-old Hayden Allen who was told five years ago he would never walk again after being paralyzed from the chest down in a motorcycle accident.
Allen said the experience of being able to stand up and walk when strapped into his robotic legs was fantastic and he felt like a normal human being again.
