流体肌肉(2)Fluidic muscle: 气动装置的“流体肌肉”是一个全新的气动驱动器，由Festo公司开发研制。它的仿生肌主要是一个中空的橡胶柱体，内置芳族聚酰胺纤维。如果流体肌肉中充满空气，它的直径扩大、长度减小，从而进行流动的弹性运动。“流体肌肉”的应用使得运动过程不仅在动作、速度和强度上与人体运动相似，而且在灵敏度上也与人体运动相似。“流体肌肉”产生的力是相同体积气缸的七倍。“流体肌肉”坚固耐用，即使是在沙滩或尘埃等极端环境中都可以使用。The pneumatic “fluidic muscle”, a completely new kind of pneumatic drive, is a development by Festo. The bionic muscles consist mainly of a hollow elastomer cylinder embedded with aramid fibres. When the fluidic muscle fills with air, it increases in diameter and contracts in length, enabling a fluid, elastic movement. The use of the fluidic muscle enables motion sequences which approach human movement not only in terms of kinematics, speed and strength, but also sensitivity. The fluidic muscle can exert ten times the force of a comparably sized cylinder, is very sturdy, and can even be used under extreme conditions such as in sand or dust.

音乐发声机The Sound Machines: 在 2007年汉诺威工业博览会上，五个自动发声机为开幕式伴奏音乐，这大大得力于Festo公司的技术。发声机中所运用的气动装置和PLC与它们过去在工业自动化中的用途完全不同。在这里它们为科技和音乐架起了桥梁。布景设计师兼机器人艺术家Roland Olbeter 开发制造了这套独一无二的“音乐发声机”，由四重奏电弦和一个鼓组成。四个弦乐器的声音和功用与电吉他相差无几，不同的是每个弦乐器上面只有一根弦。每个音乐机中都使用了21个Festo公司生产的微柱体。这些微气柱体仿音乐家左手的机械运动，并通过弦长来决定音高。在鼓上的那些微柱体制动着多个鼓槌和一个爵士乐刷。澳大利亚作曲家Elena Kats-Chernin为2007年汉诺威工业博览会特别创作了“湛蓝天空”（Fast Blue Air）。这首曲子进一步开发了音乐发声机的声音范围，甚至连气动装置产生的噪音也包括在内。音乐程序储存于乐器数字接口文件（MIDI files）中。乐声是通过三个步骤产生的。第一步是“数字化”，这时的音乐发声机由PLC控制。第二步，气动元件像吉他手一样拨动琴弦或者像弦乐器音乐家一样击打琴弦来使琴弦震动发声。第三步，乐声像电吉他一样由电子接收器接受并扩大。由此，音乐发声机可以产生各种不同的音乐效果。 Five automated sound machines provided musical accompaniment for the opening celebrations at the Hannover Messe 2007 – thanks to technology from Festo. Pneumatic components and a PLC control system were applied very differently from the way they are used in industrial automation; they created a bridge between technology and art.

空中鳐鱼Air_ray: 以自然界的鳐鱼为模板的“空中鳐鱼”是一种由远程遥控的氦气气囊和羽翼振动产生驱动力组成的混合体。它轻便的设计借助氦气的浮力让它可以在广阔的空中“遨游”，这种方法与水中的鳐鱼相似。 “空中鳐鱼”的驱动力由羽翼振动产生。利用射线效应并基于与四周有连接的拱侧翼交替推拉运动的原理，私伺服控制的羽翼可以上下移动。当一侧受到压力时，它几何形的结构会自动向受力的反方向卷曲。一个伺服驱动两片侧翼交替地纵向移动，驱使羽翼上下运动。Air_ray, modelled on the manta ray, is a remote-controlled hybrid construction consisting of a helium-filled ballonet and a beating wing drive. Its lightweight design enables it to “swim” in the sea of air using the lift from the helium in a similar way to the manta ray in water. Propulsion is achieved by a beating wing drive. The servo drive-controlled wing, which can move up and down, utilises the Fin Ray Effect and is based on alternate pulling and pushing flanks connected via frames. When pressure is exerted on one edge, the geometrical structure automatically curves against the direction of the influencing force. A servo drive pulls the two flanks alternately in longitudinal direction, thus moving the wing up and down.
