Airics_arm

Airic’s_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 form in the world of technology. The muscles are already widely found in industrial application. They are tubes of elastomer reinforced with aramide fibres. When a muscle is filled with compressed air, its diameter increases and it is simultaneously shortened.

Overview

Airic’s_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 form in the world of technology. 

The muscles are already widely found in industrial applications. They are tubes of elastomer reinforced with aramide fibers. When a muscle is filled with compressed air, its diameter increases and it is simultaneously shortened. This artificial muscle has immense starting power, and its dynamic behavior is similar to that of a human muscle. Its greatest advantage over its human counterpart is that when contracted, it requires no further supply of energy. A weight once lifted can thus be held in any position indefinitely by Airic’s_arm.
