Human-in-the-Loop Task and Motion Planning

Human-in-the-Loop Task and Motion Planning (HITL-TAMP) is a novel system that selectively gives and takes control to and from a human teleoperator. HITL-TAMP combines the benefits of imitation learning and TAMP to solve contact-rich and long-horizon manipulation.


MimicGen is a system for automatically synthesizing large-scale datasets from a small number of human demonstrations by adapting them to new scene configurations, object instances, and robot arms. This enables scalable imitation learning with minimal human effort.


The development of the RoboTurk platform was a significant part of my PhD. The video below showcases some highlights of what we've been able to accomplish using the platform.


I led development on this framework for robot learning from demonstrations. It offers a broad set of demonstration datasets collected on robot manipulation domains, and learning algorithms to learn from these datasets, in the hopes of facilitating progress in this important field. See the project website for more information.

Visuomotor Policy Learning on Real Robots

This is a closed-loop visuomotor policy operating at 20 hz using an action space consisting of an operational space controller. It was trained using a handful of human demonstrations collected with RoboTurk. See our work on Generalization Through Imitation for more information.


Simulation framework for robotic manipulation. Features include several robot models, controllers, and benchmark tasks, procedural generation of tasks, multi-modal sensors, and support for human demonstrations. See the website for more information or try the code out yourself.
