38、法解决。【译文】如果大自然已经为你做了大部分工作，为什么还要大费周章地去设计和制造无人机呢？这是一小群研究人员所持的坚定态度，他们正努力尝试使昆虫机械化。有些研究人员正致力于把像甲壳虫这样的飞行动物变成赛博格昆虫可能用于军事侦察或间谍活动。其他人通过控制蟑螂，更多地专注于昆虫学中那些令人毛骨悚然的一类。首只赛博蟑螂出现在1997年，当时东京大学的下山勲（Shimoyama Isao）通过电信号刺激蟑螂的触角，使其根据触角受到刺激而向左或向右转变方向。其他人在这种方法的基础上也做了许多实验，刺激了不同的感觉器官，如后向尾须。他们还开始给昆虫配备仪器包，让它们做一件有意义的工作：搜寻倒塌建筑物下的
39、幸存者。新加坡南洋理工大学的佐藤弘子（Sato Hirotaka）就是其 中一员。15年来，他一直致力于研究赛博昆虫。现在，他又对赛博蟑螂进行了改进。改进后的赛博蟑螂的行动不是由遥控控制，而是由他们自主导航，通过算法直接对他们仪器包中的传感器下达指令。佐藤博士给马达加斯加的发声蟑螂配备了背包，这种蟑螂长度达6厘米。背包里包含一个通信芯片，一个二氧化碳传感器，一个运动传感器，一个红外摄像头和一节微型电池。在废墟里执行搜救任务时，蟑螂会被释放出来，一边爬行一边搜寻着生命的迹象，如身体的移动、体温和呼吸产生的高浓度二氧化碳。研究人员给摄像机直接编入了一套人工智能程序，这样蟑螂就能够判定一组信号是否真的能表明有人类存在。如果蟑螂认为有幸存者，它就会向救援人员发出警报。为了测试这一装置，佐藤博士和他的团队在模拟灾区进行了试验。他们在25平方米的区域内铺设了大小形状各不相同的混凝土块，并将很多人分散其中，还放置了一些“诱饵”，如加热灯、微波炉和笔记本电脑。在程序中设置好搜索的起点和终点后，研究人员释放了这些赛博蟑螂。实验证明，该软件能够准确识别人类的概率为87%，佐藤博士认为，通过从不同角度收集多幅图像，这一成功率还可以进一步提高。该项目的下一步是改进系统，以便在户外使用。这样一来，背包的制造与配备在昆虫身上的自动装置将会商业化。佐藤博士预估，如果一切顺利的话，这项成果可以在五年内投入使用。
