Research

My research focuses on Collaborative Robots, with novel techniques and algorithms developed in several areas including Motion Planning, Trajectory Optimization and Model-based Control. Now I am mainly working on developing optimization algorithm to explore the extreme capability of the robot and improve the performance of collaborative manipulation. In addition, I am very interested in human intention estimation base on learning algorithms.
