SAIL: Faster-than-Demonstration Execution of Imitation Learning Policies
Nadun Ranawaka Arachchige*, Zhenyang Chen*, Wonsuhk Jung, Woo Chul Shin, Rohan Bansal, Yu Hang He, Yingyan Celine Lin, Benjamin Joffe, Shreyas Kousik†, Danfei Xu† Under Review, 2025 project page We propose SAIL (Speed-Adaptive Imitation Learning), a framework for enabling faster-than- demonstration execution of policies by addressing key technical challenges in robot dynamics and state-action distribution shifts. SAIL achieves up to a 4× speedup over demonstration speed in simulation and up to 3.2× speedup on physical robot. |

MimicLabs: What Matters in Learning from Large-Scale Datasets for Robot Manipulation
Vaibhav Saxena*, Matthew Bronars*, Nadun Ranawaka*, Kuancheng Wang, Woo Chul Shin, Soroush Nasiriany, Ajay Mandlekar†, Danfei Xu† ICLR, 2025 We develop a data generation framework to procedurally emulate key sources of diversity in robot datasets. Using this framework, we generate large-scale datasets with controlled variations to analyze how collection diversity and retrieval strategies impact downstream policy learning. |
