项目摘要

Army ants are unlike any other ant species. They are nomadic and therefore do not build permanent nests. Instead, between two episodes of sometimes daily migration, they build temporary nests called “bivouacs” by attaching themselves to each other. In this way they build functional structures solely out of their interconnected bodies. Army ants can assemble and disassemble bivouacs of up to a million individuals in less than an hour and can do so in almost any condition in which they find themselves. These incredible feats of constructions are of great interest for engineers looking to create swarms of robots that could autonomously assemble themselves anywhere into any desired shape. Similar swarms could, for instance, self-assemble into habitats on Mars or in disaster areas without human intervention and regardless of the state of the local environment. This collaborative research brings together biologists and roboticists to achieve two goals: understand the principles of self-assembling construction in army ants, and adapt these principles to create a new generation of robots capable of self-assembling into any desired functional structure, even in unpredictable environments. The project will also give students from K12 to Ph.D. an opportunity to learn how biological structures build themselves out of smaller units, and how fundamental knowledge of natural processes can lead to new technological developments and applications in engineering. The project has three complementary components. In Component 1, the researchers will perform field experiments to determine the rules used by army ants to self-assemble into functional structures. These studies will combine computer vision-assisted behavioral observations to measure the individual behaviors of the ants and high-definition 3D imaging using a custom-designed CT-scanner to characterize the organization and dynamics of the structure under construction. In Component 2, the result of the field experiments will be used to generate a multi-agent mathematical model and a physics-based simulation of the ant behaviors. The focus will be to design generalizable agent abstractions that allow for mathematical analysis to determine what forms of individual rules lead to correct and efficient collective outcomes as determined by the functional goal (e.g. formation of bivouac), and how modification of individual sensing and coordination capabilities affect the colony capability. Finally, in Component 3, the researchers will design a self-assembling robotic swarm with at least 30 robots. The swarm will be capable of building functional structures in unknown environments, through climbing and attaching to each other. These robots will use similar principles as army ants for collective control and allow complex 3D “organic” self-assembled structures. The goal is not to mimic ant morphology, but instead demonstrate novel robot designs that use embodied intelligence and bio-inspired control, to achieve similarly adaptive structures while also allowing simplicity and large-scale manufacturability.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

军蚁不同于任何其他蚂蚁物种。它们是游牧的，因此不会建造永久的巢。取而代之的是，在两次有时每天的迁徙之间，它们通过相互依附建立临时的巢穴，称为“露营地”。通过这种方式，他们完全从相互关联的身体中建立起功能结构。行军蚂蚁可以在不到一小时的时间内组装和拆卸多达100万个人的露营地，并且几乎可以在任何它们发现自己的条件下这样做。工程师们对这些令人难以置信的建筑壮举非常感兴趣，他们希望创造出一大群机器人，这些机器人可以在任何地方自动组装成任何想要的形状。例如，类似的蜂群可以在没有人类干预的情况下自行聚集到火星或灾区的栖息地，而不考虑当地环境的状况。这项合作研究将生物学家和机器人专家聚集在一起，以实现两个目标：了解行军蚂蚁自组装结构的原理，并根据这些原理创造新一代机器人，即使在不可预测的环境中，也能够自组装成任何所需的功能结构。该项目还将为从K12到博士生的学生提供机会，学习生物结构如何从较小的单元建立起来，以及自然过程的基础知识如何导致新的技术开发和工程应用。项目有三个相辅相成的组成部分。在组件1中，研究人员将进行实地实验，以确定行军蚂蚁用来自组装成功能结构的规则。这些研究将结合计算机视觉辅助的行为观察来测量蚂蚁的个体行为，并使用定制设计的CT扫描仪进行高清晰度3D成像，以表征在建结构的组织和动态。在组件2中，现场实验的结果将用于生成多智能体数学模型和基于物理的蚂蚁行为模拟。重点将是设计可概括的代理抽象，允许进行数学分析，以确定由功能目标(例如露营地的形成)确定的哪些形式的个人规则导致正确和有效的集体结果，以及个人感知和协调能力的修改如何影响群体能力。最后，在组件3中，研究人员将设计一个至少有30个机器人的自组装机器人群。这些蜂群将能够通过攀爬和相互附着，在未知环境中建造功能结构。这些机器人将使用类似于军蚁的原理进行集体控制，并允许复杂的3D“有机”自组装结构。该奖项的目标不是模仿蚂蚁的形态，而是展示使用体现智能和生物启发控制的新型机器人设计，以实现类似的自适应结构，同时允许简单性和大规模可制造性。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
