Meet REX: a robotic exoskeleton that enables people with disabilities to stand, walk, and stay active. It can move in all directions, including sideways and backward. Its two batteries last for 2 hours of continuous walking. The robot supports leg swings, lunges, and squats, so it can be used for rehab.
This bionic walking device has automated sideways and turning movements. The above videos show what it has to offer.
