报告摘要:The independent control of microrobot swarms is a major challenge in the field of micro/nano manipulation. In this talk, I will present our research on a new localized magnetic field generating system that can be used for the independent control of multiple magnetic microrobots. Such a system will allow for cooperative or parallel microassembly tasks with teams of magnetic microrobots. Firstly, the performance of the novel circular microcoil is modeled by analyzing the effects of input current to study the magnetic field distribution characteristics in the workspace, which is validated by finite element analysis and simulation; Then, an actuation and motion control method of coil array for microrobot is discussed. Meanwhile, the independent closed-loop control of the microrobot is realized based on visual feedback; Finally, an experimental platform for the new microcoil actuation system is built to validate the newly designed structure. The results show that the microrobot can move in eight directions at any equilibrium point. At the same time, the system is capable of independently controlling multiple microrobots and holds great potential in performing micromanipulation tasks.

报告人简介:Xinyu Liu is currently the Percy Edward Hart Professor with the Department of Mechanical and Industrial Engineering and is cross-appointed with the Institute of Biomedical Engineering, University of Toronto. Before joining the University of Toronto, he was an Associate Professor and the Canada Research Chair with the Department of Mechanical Engineering, McGill University. He obtained his B.Eng. and M.Eng. from Harbin Institute of Technology in 2002 and 2004, respectively, and his Ph.D. from the University of Toronto in 2009, all in Mechanical Engineering. He then completed an NSERC Postdoctoral Fellowship in the Department of Chemistry and Chemical Biology (with George Whitesides) at Harvard University in 2009–2011. At U of T, his research activities primarily focus on microfluidics, bioMEMS, and micro/nanorobotics, with applications in medicine and biology. He was a recipient of the Stars in Global Health Award from Grand Challenges Canada (2012), the Douglas R. Colton Medal for Research Excellence from CMC Microsystems (2013), the Christophe Pierre Award for Research Excellence from McGill University (2017), and the Young Scientist Award from the Microsystems & Nanoengineering Summit (2018), the Highly Cited Paper Award from Microsystems & Nanoengineering (2020), and the Outstanding Paper Award from Materials Horizons (2020). He is a Senior Editor of IEEE ROBOTICS AND AUTOMATION LETTERS and Microsystems & Nanoengineering, and an Associate Editor of IEEE TRANSACTIONS ON AUTOMATION SCIENCE AND ENGINEERING, IEEE TRANSACTIONS ON NANOTECHNOLOGY, International Journal of Advanced Robotic Systems, and IET Cyber-Systems and Robotics. He also served on the Editorial Boards of the three major IEEE Robotics and Automation Society Conferences (ICRA, IROS, and CASE).
