The Robotics Part of Micro and Nano Robots
微纳机器人的机器人学视角
Brad Nelson
ETH Zürich, Switzerland
Abstract: Micro and nano robots have made great strides since becoming a focused research topic over two decades ago. Much of the progress has been in material selection, processing, and fabrication, and paths forward in developing clinically relevant biocompatible and biodegradable micro and nano robots are becoming clear. Our group, as well as others, maintain that using biocompatible magnetic composites with externally generated magnetic fields and field gradients is perhaps closest to clinical application. One of the most challenging aspects of the field is in the development of the magnetic navigation system (MNS) that generates the fields and field gradients needed for microrobot locomotion. In this talk, I will present an overview of MNSs and show how these systems are fundamentally robotic in the way they must be designed and controlled. Decades of work in robotic manipulation can be brought to bear on this problem as we move forward in bringing MNS technology to the clinic. I will also look at recent efforts in creating more intelligent micro and nano robots that exhibit increasingly complex behaviors, some of which can even be programmed in situ. The field appears to be on the cusp of realizing the fantastic voyage.
在过去的二十年中,大量的研究聚焦于微纳米机器人,使该领域取得了长足的进步。这些进步主要集中在材料选择、加工和制造方面;同时,面向临床应用的发展道路也正在变得清晰——即开发具有生物相容性及可生物降解的微纳米机器人。我们认为使用生物相容性磁性复合材料,结合外源磁场和磁场梯度的方案可能是临床应用中最可行的方案。该研究方向最具挑战性的问题之一是开发磁导航系统 (MNS),从而生成微型机器人运动所需的场和场梯度。在本次演讲中,我将介绍磁导航系统,并分析为何这些系统在其设计和控制的角度上来看根本上也是机器人。随着我们将 MNS 技术引入临床,在机器人操纵方向上数十年的研究工作将能够应用于此。另外,我还将介绍近些年来在创建更智能的微纳机器人方面所做的努力——这些机器人表现出越来越复杂的行为,其中一些甚至可实现原位编程。该领域似乎正处在开启一段奇妙旅程的前夜。
Bio: Brad Nelson is the Professor of Robotics and Intelligent Systems at ETH Zürich and has recently become the Chief Scientific Advisor of Science Robotics. He has over thirty years of experience in the field and has received a number of awards in robotics, nanotechnology, and biomedicine.
