气动驾驶Airmotion_ride
流体肌肉和机械系统相互作用在“气动驾驶”中实现了优良驾驶和飞行的模拟环境。一个并联结构的六足系统使用6块Festo流体肌肉制造出了驾驶和飞行的感觉,犹如身临其境。在这次项目中,气动装置供应商巨头Festo公司证实了一个精密水力机构的替代方案,既吸人眼球,又有成本效益。The interplay of fluidic muscles and mechatronic systems in the Airmotion_ride makes it possible to generate an extraordinary range of driving and flight simulations. A hexapod structure using parallel kinematics, with six Festo fluidic muscles, creates a realistic driving and flying sensation. In this project, leading pneumatics supplier Festo demonstrates an exciting, cost-effective alternative to complicated hydraulic constructions.

单结晶体管的自振荡电路-机电传动控制第22讲
单结晶体管 单结晶体管(简称UJT)又称基极二极管,它是一种只有一个PN结和两个电阻接触电极的半导体器件,它的基片为条状的高阻N型硅片,两端分别用欧姆接触引出两个基极b1和b2。在硅片中间略偏b2一侧用合金法制作一个P区作为发射极e。所谓振荡,是指在没有输入信号的情况下,电路输出一定频率、一定幅值的电压或电流信号。当合闸通电时,电容C上的电压为零,管予截止,电源VBB通过电阻R对C充电,随时间增长电容上电压uC逐渐增大;一旦UEB1增大到峰点电压UP后,管子进入负阻区,输入端等效电阻急剧减小,使C通过管子的输入回路迅速放电,iE随之迅速减小,当UEB1减小到谷点电压Uv后,管子截止;电容又开始充电。上述过程循环往返,只有当断电时才会停止,因而产生振荡。

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.

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.
