自动风筝Sky_liner
放飞风筝需要娴熟的技能,Festo公司凭借其“空中自动化风筝”首次证实运用机电学原理可以实现风筝全程自动化控制。这是其在运用流动气流核心技术上的新发展。 “空中自动风筝”包含两个分别用机电控制器操纵的双线风筝。运用伺服电机和人造风,这两个风筝就可以实现室内自动化操作。各风筝线通过快速开关阀连接到Festo公司生产的DMSP射流臂,它可以缩短风筝线的长度。如果风筝断线,通过射流臂收缩风筝线就可以使其平稳飞行。It takes a fair amount of skill to fly a kite. With its Sky_liner project, Festo has become the first company to demonstrate that fully automated control can be achieved with the aid of mechatronics, thus linking a new development to its core competency of automation using moving air. Sky_liner consists of two two-line kites, each of which is controlled using a mechatronic control unit. The two kites are operated automatically indoors, using servo motors and artificial wind. Each line is connected via fast-switching valves to a fluidic muscle DMSP from Festo, which shortens the line and counterbalances the kite by contracting when the kite breaks away.

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.
