水下鳐鱼Aqua_ray: “水下鳐鱼”是一种远程控制的水力驱动鱼，它的形状和运动都以鳐鱼为模板。 “水下鳐鱼”的中央驱动和控制单元采取了Festo公司特有的流体肌肉形式，并结合了射线效应——一种基于鱼鳍的功能解剖的设计。这使得模仿自然的鱼鳍推进近乎完美。由于“水下鳐鱼”能够任意移动，可以作为一水压滑翔机或者振翅驱动，节约了大量能源。“水下鳐鱼”的形状和运动的方式让它可广泛用于海洋学领域而不破坏自然环境。Aqua_ray is a remote-controlled fish driven by water hydraulics, the shape and movements of which have been based on the model of a manta ray.The central drive and control unit of Aqua_ray takes the form of a fluidic muscle from Festo, in combination with the Fin Ray Effect®. The Fin Ray Effect® is a design based on the functional anatomy of a fish’s fin. This makes it possible to imitate the fin propulsion of the natural role model almost perfectly. As the Aqua_ray can be manoeuvred extremely well, and can be operated both as a hydrostatic glider and with an active wing beat, substantial energy savings can be achieved. Thanks to its shape and its means of locomotion, the Aqua_ray can be used in wide ranging areas of oceanography without disrupting the natural environment.

气动手臂AirArm: 通过分析龙虾和蝗虫的腿以及人类手指的形态得到了气动手臂的灵感。它是一个带有外部骨架的两节式桥臂，由气动肌腱驱动。智能控制技术使气动手臂能赶上水滴的速度。气动手臂在技术上的意图是能够在指定半球状运行范围内延伸到尽可能多的区域。选择一般技术实践的常规原理，使带气动肌腱的两节式伸缩系统同时反向运行。 AirArm is biologically inspired by analyses of lobsters’ and grasshoppers’ legs and by human pointing gestures. It is a two-segmented arm with an external skeleton powered by pneumatic muscles. Intelligent control technology enables AirArm to catch drops of water. The technical purpose of AirArm is to reach as many points as possible within a hemispherical operating range defined from a specified point in space. A two-segmented flexing system with muscles operating together in contrary motion was chosen as the general principle for technical realisation.

立体鼹鼠机—吸引人的可编程机器人系统: 立体鼹鼠机在不久的将来会在技术培训中发挥重要的作用。这些备有电脑芯片的立方体可以紧密接连接在一起。鼹鼠机之间可以相互沟通交流。能量和信号从一个立体鼹鼠机传递给下一个，这样也保证了能量的供应以及信号的传递。年轻人可以用这种机器给自己制造的机器人编程。Molecubes – an attractive programmable robotics system Molecubes could play a significant role in technical training in the near future. These cubes, fitted with computer chips, can be successively attached to each other. Each Molecube communicates with all the other cubes; the energy supply and transmission of signals from one Molecube to the next are thereby ensured. Young people can use the Molecubes to build and program their own robots.

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.
