Airacuda 採用氣動驅動，在構造、設計和運動學方面遵循生物模型。有四個氣動肌腱，可達成 s 形運動，並且尾鰭可以平順偏轉。
The fin itself works according to the Fin Ray Effect® principle, which can also be observed in a natural fish fin. When lateral pressure is applied, the geometric structure automatically curves against the direction of force. This allows the Airacuda to deploy the full power of its fin deflection in the water, just like its biological role model.
Like its natural role model, the Airacuda uses an air bubble to balance itself in water. Inside there is a cavity that can be flooded with water or filled with air. A pressure sensor determines the depth and sends a signal to the electronics, which then open the corresponding valves and supply the chamber with vacuum or compressed air. All electronic and pneumatic components are installed in waterproof housing inside the head. The structure is clad with a silicone skin.
