The NASA has invented a powered robotic exoskeleton for the astronauts Notably, the suit has been co-developed by the NASA and the Florida Institute for Human and Machine Cognition. The new armour has as aim to keep the astronauts healthier when they are in space. Further research have shown that the robotic exoskeleton can help astronauts to exercise effectively even if they are away from the planet Earth. Other scientists have advanced that the new robotic exoskeleton can help paraplegics to walk. Indeed, this technology can aid people who never walked, to walk for the first time Basically, the armour is armed with 4 motorised joints located at the hips and knees; 6 passive joints up and down the leg which allow for extra freedom of motion...
