About
Liangming Chen is a robotics and control systems researcher whose work centers on multi-robot coordination, formation control, and relative localization. He is perhaps best known for pioneering the theory of **angle rigidity**, introduced in his highly cited 2019–2020 papers, which addresses the fundamentally challenging problem of stabilizing multi-agent formations when robots can only measure relative angles to their neighbors — without access to distance or position data. This theoretical contribution, which has attracted over 112 citations, opened a new avenue in formation control by providing rigorous mathematical foundations for angle-based sensing frameworks. Chen's research extends beyond theory into practical multi-robot applications, including distributed circumnavigation with time delays, air-ground heterogeneous formations for search-and-rescue missions, and 3-D relative localization using angle and self-displacement measurements. His 2025 work on relative localizability further advances the field by addressing how partial inter-robot sensing information can still enable robust multi-robot coordination. He has also explored recurrent neural network approaches for controlling redundant robotic manipulators. Collectively, Chen's contributions bridge rigorous geometric theory with real-world autonomous systems, making him a notable emerging voice in the multi-robot systems research community.
