Airic's arm is a robotic arm inspired by your own arm. The company describes it as a "combination of mechatronics and the biological model of a human being."
The mechanical foundation - the "skeleton" - of Festo's Airic's_arm is literally a metal version of the human skeletal structure. The radius and ulna (primary bones of the forearm), the metacarpals (hand and fingers) and the shoulder and shoulder blade are duplicated.
The musculature of the Festo Airic's_arm is comprised of Festo's "Fluidic Muscle," a pneumatic actuator of a type similar to those first demonstrated in the 1950's. Festo claims that their fluidic muscle design offers quicker repetition and high acceleration of mechanical parts, combined with a better power to weight ratio. The movements of the robotic arm are remarkably lifelike (see video).
Festo's Airic's_arm is a pretty good fit for a specialized robotic arm from the 1958 Harry Harrison story Simulated Trainer:
He watched the panel slip back in the wall next to him and the hypo arm slide through, moving erratically like a snake as its metal fingers sought him out... (Read more about Harry Harrison's robotic arm)
