气动机器人手臂Airics_arm: “气动机器人手臂”的灵感来源于自然界。结合机电一体化和人类仿生学模型，机器人手臂彰显了未来自动运动序列新的可行性。 “气动机器人手臂”由机器骨骼和机器肌肉组成。30块肌肉连接带动骨骼移动，包括尺骨、桡骨、掌骨和指骨以及肩关节和肩胛。这种连接技术目前还没有发明出来。机器肌肉是Festo公司的一个产品，已经广泛应用于工业应用，叫做流体肌肉。这种技术使用了Festo公司的微型创新压力比例阀，让我们能够精确控制设计的力量和硬度。这些执行器与机电一体化系统和软件的技术水平同步。扩展“气动机器人”的传感器系统也非常合理，就像开发后背、臀部和脖子部位一样，比如安装摄像头或者有感知能力的零件。这些扩展让机器人能够在更加危险的情况下工作发挥了重要作用。 Airics_arm is inspired by nature. Combining mechatronics and the model of human biology, the robotic arm shows new possibilities in automated motion sequences of the future. Airics_arm is equipped with artificial bones and muscles. 30 muscles move the bone structure comprising the ulna and radius, the metacarpal bones and the bones of the fingers as well as the shoulder joint and the shoulder blade; joints that are not found in the world of technology. The muscles are a product of Festo and are already widely used in industrial practice under the name of Fluidic Muscle. This technology, combined with very small and highly innovative piezo proportional valves from Festo, enable us to accurately control the designs forces and rigidity. These actuators are coordinated by state-of-the-art mechatronic systems and software. Extending the system of sensors of Airics_arm, e.g. with cameras or elements for tactile perception, is just as plausible as the development of a design for a back, hip and neck. These extensions will also play an important role in robotics as even more dangerous and hazardous situations in technology could be assigned to them.

气动溜溜球YoYo: 玩溜溜球需要技巧和耐心。通过YoYo系统，Festo证明了在机电元件的帮助下，加上Festo利用流动空气的核心自动化竞争力，能实现全自动控制。 YoYo由3个独立的溜溜球组成，其规格也各不相同，分别为16, 20 和24。所有溜溜球均采取不同种类的麦克斯韦转轮，每一个均由气动肌腱驱动。 Playing with a yo-yo takes skill and patience. With its YoYo, Festo has demonstrated that fully automated control can be achieved with the aid of mechatronics, thus linking with Festo core competency of automation to using moving air. The YoYo consists of three independent yo-yos of different sizes, 16, 20 and 24. All the yo-yos take the form of Maxwell wheels of various kinds, with each one being driven by a pneumatic muscle.

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.
