Robotics and automation company Festo took a page from Mother Nature's design book and designed an air-powered robotic arm modeled on a human one. The result? Airic's arm with "Fluidic Muscle," a combination of artificial bones and muscles that allow the arms to move gracefully:
The Airic’s_arm is a robotic arm fitted with artificial bones and muscles. The bone structure, consisting of the human bones such as ulna and radius, metacarpal bone and finger bone, shoulder joint and shoulder blade – joints that do not occur as such in the technical world – is moved via 30 muscles.
