IMechE - Swimming Microrobots for Biomedical Applications

7th December 2021 6:00 pm

Swimming microrobots are envisioned to be able to freely move inside the human body and reach currently inaccessible areas to perform delicate biomedical operations such as diagnosis, surgery, cell transportation, and localized drug delivery. Application of these microrobots will revolutionize medicine and have a high impact on society. However, there are still many challenges to be addressed. One of these challenges includes powering and control of microrobots. Researchers have been inspired by motile bacteria to develop swimming methodologies at microscale which are different than methods at macroscale. The use of external magnetic fields for powering microrobots would be promising. However, uncertainties in dynamics as well as magnetic actuator nonlinearities make control of robots challenging at microscale. To achieve a reliable biomedical microrobotic system, many kinds of expertise such as micro-/nanotechnology for fabrication, robotics for design and control, mechanics for modelling at microscale, and medicine for operation are necessary to bring together. In this event, theoretical and experimental results and challenges facing application of microrobots in biomedicine will be discussed.

Dr. Ali Ghanbari graduated with a Ph.D. in Mechanical Engineering with a focus on swimming microrobots from Amirkabir University of Technology in 2011. He was a Postdoctoral Research Fellow in Biomicrorobotics Lab at Robotics Engineering Department of Daegu Gyeongbuk Institute of Science and Technology (DGIST) and a guest researcher in Multi-Scale Robotics Lab at ETH Zürich. He worked as an Assistant Professor at Tafresh University and as a Research Fellow at the University of Leeds. Currently, he is a Lecturer in Mechanical Engineering in the School of Engineering at the University of Central Lancashire.
