North Carolina State University researchers have developed technology that allows cyborg cockroaches, or biobots, to pick up sounds with small microphones and seek out the source of the sound. The technology is designed to help emergency personnel find and rescue survivors in the aftermath of a disaster.

研究人员还开发了可以用作“无形的围栏”的技术，以将生物机器人保留在灾区。

“In a collapsed building, sound is the best way to find survivors,” says Dr. Alper Bozkurt, an assistant professor of electrical and computer engineering at NC State and senior author of two papers on the work.

生物机构配备了控制蟑螂运动的电子背包。Bozkurt的研究团队使用麦克风创建了两种类型的定制背包。一种类型的生物机器具有一个麦克风，可以从任何方向捕获相对高分辨率的声音，以无线传输到第一反应者。

The second type of biobot is equipped with an array of three directional microphones to detect the direction of the sound. The research team has also developed algorithms that analyze the sound from the microphone array to localize the source of the sound and steer the biobot in that direction. The system worked well during laboratory testing. Video of a laboratory test of the microphone array system is available athttp://www.youtube.com/watch?v=ojxepcv-fmw。

Bozkurt说：“目的是使用具有高分辨率麦克风的生物机器人来区分重要的声音（例如寻求帮助的声音）与无关紧要的声音（例如泄漏的管道）进行区分。”“一旦确定了重要的声音，我们就可以使用配备麦克风阵列的生物机器人在这些声音的来源中零。”

A research team led by Dr. Edgar Lobaton has previously shown that biobots can be used to map a disaster area. Funded by National Science Foundation CyberPhysical Systems Program, the long-term goal is for Bozkurt and Lobaton to merge their research efforts to both map disaster areas and pinpoint survivors. The researchers are already working with collaborator Dr. Mihail Sichitiu to develop the next generation of biobot networking and localization technology.

Bozkurt’s team also recently demonstrated technology that creates an invisible fence for keeping biobots in a defined area. This is significant because it can be used to keep biobots at a disaster site, and to keep the biobots within range of each other so that they can be used as a reliable mobile wireless network. This technology could also be used to steer biobots to light sources, so that the miniaturized solar panels on biobot backpacks can be recharged. Video of the invisible fence technology in practice can be seen athttp://www.youtube.com/watch?v=mwgakd7_fam。

A paper on the microphone sensor research, “Acoustic Sensors for Biobotic Search and Rescue,” was presented Nov. 5 at the IEEE Sensors 2014 conference in Valencia, Spain. Lead author of the paper is Eric Whitmire, a former undergraduate at NC State. The paper was co-authored by Tahmid Latif, a Ph.D. student at NC State, and Bozkurt.

The paper on the invisible fence for biobots, “Towards Fenceless Boundaries for Solar Powered Insect Biobots,” was presented Aug. 28 at the 36th Annual International IEEE EMBS Conference in Chicago, Illinois. Latif was the lead author. Co-authors include Tristan Novak, a graduate student at NC State, Whitmire and Bozkurt.

“用于生物搜索和救援的声学传感器”

作者: Eric Whitmire, Tahmid Latif, and Alper Bozkurt, North Carolina State University

提出了：11月5日在西班牙瓦伦西亚的IEEE传感器2014

抽象的：神经工程的进步已使昆虫运动的直接控制。昆虫生物机构具有自然能够爬过小空间的能力，比传统的合成机器人具有独特的优势。这种生物机构的网络物理网络可能被证明可用于在不确定的灾难环境中搜索和拯救应用程序。我们以前的工作表明使用基于Kinect的计算机视觉平台对马达加斯加的嘶嘶蟑螂进行了控制。现在，我们展示了低功率昆虫安装的声学传感器，用于将来在环境映射和捕获幸存者的定位中使用。我们的实验表明，昆虫安装的麦克风阵列可以定位声源。

“朝着太阳能昆虫生物机器人的无栅栏边界”

作者: Tahmid Latif埃里克•惠特米尔和特里斯坦•诺瓦克Alper Bozkurt, North Carolina State University

提出了：8月28日，在伊利诺伊州芝加哥的第36届年度国际IEEE EMB会议

抽象的：用仪器昆虫进行远程导航的演示，例如马达加斯加的嘶嘶蟑螂Gromphadorhina Portentosa，已使生物生物剂的概念用于搜索和救援任务以及环境监测应用程序。生物机器人可以形成以自然灾害后的未知和动态环境中建立的移动传感器网络的节点，以查明幸存的受害者。我们在这里首次证明了昆虫生物机器人的无形围栏的概念，其最终目标是将昆虫生物机器人彼此或基站保持一定距离或基站以确保可靠的无线网络。在延长的任务持续时间内，该无登记的边界还将用于引导昆虫朝着轻度源来实现其机上电池的自动量太阳能充电。
