Track2Art: Motion-Centric Articulated Object Model Recovery from 2D Point Trackers
Recovering articulated object parts, directed kinematic graphs, joint types, and joint geometry directly from RGB-D interaction videos and persistent point tracks.
About
I am currently working as a VLA model researcher at Lumos Robotics, where I focus on robot manipulation and long-horizon tasks. My recent work includes depth-modality integration for VLA models, mask-guided object-centric manipulation, and improving non-Markovian long-horizon task execution through subtask decomposition and high-level memory modules. More broadly, I am interested in physical world models, VLA models, and robot learning that can understand and interact with the physical world.
I am seeking PhD opportunities in robotics, especially around physical world models, VLA models, and other related areas.
