Airics_arm is a robot arm with artificial bones and muscles. A total of 30 muscles move the bone structure which, as with our own arms, consists of ulna and radius, metacarpal and finger bones, a shoulder joint and a shoulder bone-joints that are otherwise not encountered in this formin the world of technology. Airics bones have not grown of their own accord, nor do they automatic- ally heal following a fracture. They were designed on computer and are grown in a three-dimensional polyamide structure using a state-of-the-art laser sintering process. The muscles, a product of Festo, are already widely found in industrial application under the name of Fluidic Muscles. These are tubes of elastomer reinforced with aramide fibres. When a Fluidic Muscle is filled with compressed air, its diameter increases and it is simultaneously shortened.
