About

William Chu is a pioneering researcher in the field of micro-robotics and precision assembly, with a focus on diamagnetic levitation technologies. His major contributions center on the development of milli-scale robots that operate without physical contact, enabling unprecedented manipulation of micro-scale components. In his highly cited 2017 work, Chu demonstrated automated 2D micro-assembly of 10-μm polymer microspheres and silicon parts using diamagnetically levitated milli-robots, achieving long-term open-loop stability through optical feedback at 27 Hz. This breakthrough laid the foundation for his 2018 study on heterogeneous 3D assembly, which expanded the technique to multi-layer, multi-material constructs. With over 60 combined citations, Chu’s work has significantly advanced the capabilities of non-contact micro-manipulation, offering a scalable solution for assembling complex micro-devices. His achievements are notable for bridging the gap between macro-scale robotics and nano-scale precision, with potential applications in MEMS fabrication, biomedical devices, and advanced manufacturing. Chu’s research continues to inspire new approaches to automated micro-assembly, making him a key figure in the evolution of milli-robotics.
