Roomba builds a static map of your home by moving around. Can a robot create articulated models of indoor scenes through its physical interaction? Ditto in the House builds digital twins of articulated objects in everyday environments. #ICRA2023 Website: ut-austin-rpl.github.io/HouseDitto/
What if the form of visuomotor policy has been the bottleneck for robotic manipulation all along? Diffusion Policy achieves 46.9% improvement vs prior StoA on 11 tasks from 4 benchmarks + 4 real world tasks! (1/7) website : diffusion-policy.cs.columbia.edu paper: arxiv.org/abs/2303.04137
Our work on a unified approach to imitation learning and learning from preferences was featured on the Microsoft Research Blog! Try this method out (github.com/hari-sikchi/raβ¦) to obtain SOTA results in imitation learning. A collab with Akanksha Saran, W. Goo, Scott Niekum
S3O: Symbolic State Space Optimization tl;dr: Solving Task and Motion Planning problems without predefining task-level state space in mobile manipulation domains. w/ Yifeng Zhu Yan Ding Yuqian Jiang Yuke Zhu Peter Stone Shiqi Zhang Check it out at @IROS2023 next week!
Context-aware navigation requires object/terrain-level understanding - in support of this, we are thrilled to release CODa, the largest multi-class, multi-modal urban robotics dataset to date. amrl.cs.utexas.edu/coda/ Work done with a fantastic team from UT Austin's Autonomous Mobile Robotics Laboratory! A short π§΅, 1/7
Huge congratulations to Peter Stone for receiving the ACM Allen Newell Award! π We are proud to celebrate this incredible recognition of his groundbreaking contributions to AI and computer science.π #ACM #AAAI #AllenNewellAward
How to prevent behavior cloning policies from drifting OOD on long horizon manipulation tasks? Check out Latent Policy Barrier (LPB), a plug-and-play test-time optimization method that keeps BC policies in-distribution with no extra demo or fine-tuning: project-latentpolicybarrier.github.io
If you are working on multi-agent RL and Ad Hoc Teamwork, please check out this new effort from my colleagues, led by Caroline Wang
Both Youngju Yoo and Jiaheng Hu are in CoRL. If you are interested in our work in in-context imitation learning, please reach out and talk to them!
We hope that RoboSSM will inspire the robot learning community to rethink about suitable neural architectures for miltitask manipulation policies. RoboSSM is led by Youngju Yoo, who will be applying for PhD. She is a very capable candidate, please consider!
Everyone says they want general-purpose robots. We actually mean it β and weβll make it weird, creative, and fun along the way π Recruiting PhD students to work on Computer Vision and Robotics UMD Department of Computer Science for Fall 2026 in the beautiful city of Washington DC!
