Airacuda 采用气动驱动，在构造、设计和运动学方面遵循其生物模型。有四个气动肌腱，可实现 s 形运动，并且尾鳍可以平顺转向偏转。
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.
