US experts have developed what they say are the most biologically-accurate robotic legs yet. Writing in the Journal of Neural Engineering, they said the work could help understanding of how babies learn to walk - and spinal-injury treatment. They created a version of the message system that generates the rhythmic muscle signals that control walking.
A 32-year-old man whose knee and lower leg were amputated in 2009 after a motorcycle accident is apparently the first person with a missing lower limb to control a robotic leg with his mind. http://www.nature.com/news/rewired-nerves-control-robotic-leg-1.13818?WT.mc_id=PIN_NatureNews Credit: Hargrove, L.
