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.
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.
