You can study"link mechanism"(a mechanism to convert the linear movementof
cylinders into the rotation movement such as open/close of the jaw) by assembling
the real kit. (Though there are a lot of models of motor mechanism, which are simple
and easy- to-understand, there are few models of link mechanism.)
You can learn about air cylinders, pneumatic equipment and circuits by using thereal thing.
You can understand the roles of component parts, valves, speed controllers, piping
and pressure gauges by using the real thing.

SPEC
-Moving points: 8 axes (Right eye: Right/left, Left eye: Right/left, Eyes: Up/down, Eyelids: Open/close,
Mouth: Open/close, Neck: Back/forth, Neck: Tilt right/left, Neck: Rotate)
