空中水母AirJelly: 空中水母的环境是空气。与水下水母不同，远程控制的水母——空中水母不是在水中游，而是在广阔的空中滑翔，因为它有一个中央电机装置和一个智能听候指令的体系。它能够这样是因为它有一个充满氦气的球形网。空中水母仅有的动力来源就是连接中央电动驱动器的两个锂离子电池。中央驱动器把动力传输到一个锥齿轮上，然后再传给八个连续的直齿轮，直齿轮通过曲柄带动水母上的八个“触角”。每个“触角”都设计成鱼鳍鳍条结构。把蠕动当做这个球形网的动力到目前为止在空军史上还是空白。空中水母是第一个以蠕动为驱动力的室内飞行物体。这种新型的驱动理念基于反弹原理的助推力，让水母轻轻地在空中穿行。 AirJellys environment is the air. Unlike AquaJelly, the remote-controlled jellyfish AirJelly does not swim through water, but instead glides instead through a sea of air thanks to its central electric drive unit and an intelligent, adaptive mechanism. It is able to do so because it consists of a helium-filled ballonett. AirJellys sole source of power is two lithium-ion polymer batteries connected to the central electric drive unit. It transmits the force to a bevel gear and from there to a succession of eight spur gears, which move the eight tentacles of the jellyfish via cranks. Each tentacle is designed as a structure with Fin Ray Effect . Propulsion of a ballonett by means of peristaltic motion is hitherto unknown in the history of aviation. AirJelly is the first indoor flight object with peristaltic drive. This new drive concept, with propulsion based on the principle of recoil, moves the jellyfish gently through the air.

带有鳍形夹具的仿生三角架—多方位运动和自动抓取: 仿生三角架利用了自然界中鱼鳍的结构，首次将三维空间应用到空中企鹅和水下企鹅项目中，以便实现高效和多方位的自动化。三个可扩展伸缩的金丝玻璃纤维杆降低了需要被替换的量，同时允许最大90度的运动。BionicTripod with FinGripper versatile movement and adaptive grasping The BionicTripod makes use of the bionic Fin Ray® structure, which was transferred to three-dimensional space for the first time in the AirPenguin and AquaPenguin projects for efficient, versatile automation. Three extendible and retractable filigree fibreglass rods reduce the mass to be displaced, while allowing a maximum scope of movement of up to 90 degrees.

空中企鹅AirPenguin_Festo仿生技术: airPenguin –空中企鹅——自动飞翔的机器企鹅. 随着空中企鹅的问世， Festo公司的工程师们创造了人造企鹅，并教会他们“在空中自主飞行”。为此，控制和调节技术进一步发展成自我调节生物机电一体化系统，该系统可以在今后的生产适应性发挥作用。一组3只自动飞行的企鹅自由盘旋在空中超声发射站监控下的固定区域。企鹅能够自由的在这个空间内移动，因为一个微控制器赋予了他们自由的意志来以开拓这片空间。 autonomously flying robotic penguins With the AirPenguins, the engineers from Festo have created artificial penguins and have taught them "autonomous flight in the sea of air". For this purpose, control and regulating technology had to be further developed into self-regulating biomechatronic systems, which could also play a future role in adaptive production. A group of three autonomously flying penguins hovers freely through a defined air space that is monitored by ultrasound transmission stations. The penguins are at liberty to move within this space; a microcontroller gives them free will in order to explore it.

Airacuda - 通过远程控制的气动鱼: Airacuda 能在水中灵活游动，几乎完全不发出声响：它的设计、外形和动力遵循它的生物模型。电子和气动部件隐藏在它防水的头部中，它们通过两根气动肌腱控制尾部的S形运动。另外两根气动肌腱用于掌握方向。鱼鳍由交互牵引和压力边缘构成，它们通过骨架连接。如果一个边缘受压，几何结构会自动向与作用力相反的方向弯曲。这听上去很复杂，但原理其实很简单，依据这个原理，鱼的鳍可以在水中有力地划动。这种结构被称为鳍条效应®。气动肌腱是Festo的创新产品。它的功效不比一根真正的肌肉差，但它是通过压缩空气驱动的。
