Zhixuan Xu | 徐志轩
Hi there! I am a fourth-year undergraduate (Sep. 2020 - ) student of College of Control Science and Engineering and Chu Kochen Honor College at Zhejiang University. I am currently majoring in Robotics Engineering with a minor in Computer Science and Technology. Nowadays, I am a research assistant working with Prof. Lin Shao at NUS. I am also lucky to work with Kechun Xu, Prof. Rong Xiong and Prof. Yue Wang at ZJU.
I'm interested in combining learning and control to enhance generalizable dexteorus manipulation.

UniContact: A Basic Model for Robotic Manipulation of Contact Synthesis on Rigid and Articulated Rigid Bodies with Arbitrary Manipulators
Gang Yang, Zhixuan Xu, Zixuan Liu, Jichen Sun, Hanwei Fan, Xinghao Zhu, Lin Shao
TL;DR: Generated a large scale dataset for contact synthesis and developed a neural network for arbitrary manipulators to choose contact positions on a random rigid or articulated rigid object to generate a specified target wrench. Proposed a collision-free optimization framework to jointly optimize robot configurations, contact force and positions.

TL;DR: Proposed a self-supervised approach to reconstruct and extract object shapes and 6D poses from monocular human demonstration RGB videos using differentiable rendering. Combined global contact sampling with a robust gradient approximation technique for model-based robotic manipulation with the aid of differentiable simulation.
