About

Defu Lin is a robotics and autonomous systems researcher whose work spans computer vision, control theory, and multi-robot coordination, with a particular focus on operating in challenging, GPS-denied environments. His early contributions made a significant mark in autonomous UAV navigation, most notably through his 2018 work on ellipse proposal and convolutional neural network-based landing marker detection, which garnered 33 citations and addressed the critical challenge of reliable autonomous landing under real-world computational constraints. Complementing this, his 2015 research on chattering-free adaptive fast convergent terminal sliding mode controllers — cited 28 times — advanced precision position tracking for robotic manipulators by elegantly combining linear and terminal sliding mode techniques to eliminate the notorious discontinuity problem in classical approaches. More recently, Lin has turned his attention to complex maritime robotics, developing both autonomous aerial transport systems and heterogeneous multi-robot platforms capable of object retrieval in GNSS-denied open-sea conditions — environments that push the boundaries of perception, localization, and coordination. His body of work reflects a consistent drive to bridge theoretical control frameworks with practical autonomous systems, making him a noteworthy contributor to the growing field of field robotics and intelligent unmanned systems.
