德国机器人技术公司推出仿生雨燕，可实现在室内飞行

【极果播报】相信大家之前多多少少都听说过仿生这个词，它说的是科技仿照自然界的某种动物去创作一样机器化的类似物。近日，在这一领域又有了新发现，德国机器人技术公司Festo最新作品之一是真正像鸟一样飞翔的燕子。

Festo称它们为“仿生雨燕”，可以将它们视为人工燕子。目前该款产品可实现个人在室内以协调的方式飞行，并通过室内GPS信号不断感知它们在太空中的位置和飞行模式，这是不是有点太神奇了？

这只仿生鸟长44.5厘米，翼展为68厘米，体内电源重量仅42克时，为了尽可能逼真地执行飞行操作，这款新产品的机翼以鸟类的羽毛为模型。单个薄片由超轻、柔软但非常坚固的泡沫制成，并像木瓦一样彼此叠放。

它们连接到碳纤维套筒上，并像自然模型一样连接到实际的翅膀。在机翼向上冲程期间，单个薄片会扇出，以便空气可以流过机翼。这意味着这只仿生鸟只需要较少的力量即可将翅膀拉起。

在下冲程期间，叶片会关闭，因此可以产生更多的飞行力。由于机翼是这种接近自然的复制品，因此BionicSwifts的飞行性能比以前的机翼跳动驱动器更好。除此之外，还有许多技术都驻留在鸟的体内，例如机翼拍打机构、两个伺服器、各种电路板、电池和变速箱。

不过未来德国机器人技术公司Festo是否会大量生产这些是目前还不能确定。但是该公司表示，像这样的技术（禽类有能力在狭窄的空间内相互避开）可以在工厂中使用，也就代表着或许仅仅可能会小范围内销售或限量销售。
