Biography

Guangning Tan (TGN, 谭广宁), was born and raised in Guangzhou, China. He received in 2010 his Bachelor degree in Communication and Electrical Engineering at Sun Yat-sen University, Guangzhou, and in 2012 and 2016 his M.Eng and PhD respectively in Computational Science & Engineering at McMaster University, Canada. While at McMaster, he was the main author of the DAESA package, a Matlab tool for structural analysis of differential-algebraic equation systems.


After finishing post-doc at MIT, TGN joined Mujin Robot Controller Inc. (Tokyo, Japan) and became the Lead Computational Scientist and Software Engineer. He tackles one of the most difficult computational problems in robotics kinematics automation. He authored IKFast++, a C++ package that solves inverse kinematics (IK) problems of any industrial robots. Within IKFast++ he has developed sophisticated mathematical theories, state-of-the-art numerical & combinatorial algorithms, and efficient modern C++ code. IKFast++ drastically exceeds the capabilities of its predecessor ikfast.py originated by Mujin's CTO Dr. Rosen Diankov, and generates much more reliable and versatile C++ solvers that can be used in numerous robotics automation applications.
