Very excited to start sharing some of the work we have been doing at Amazon FAR. In this work we present OmniRetarget, which can generate high-quality interaction-preserving data from human motions for learning complex humanoid skills. High-quality re-targeting really helps the reinforcement learning. Why? The control policy optimization landscape is much nicer for (near)feasible trajectories than for trajectories with artifacts like (e.g.) foot skating or ground penetration.

Humanoid motion tracking performance is greatly determined by retargeting quality! Introducing 𝗢𝗺𝗻𝗶𝗥𝗲𝘁𝗮𝗿𝗴𝗲𝘁🎯, generating high-quality interaction-preserving data from human motions for learning complex humanoid skills with 𝗺𝗶𝗻𝗶𝗺𝗮𝗹 RL: - 5 rewards, - 4 DR terms, - Proprio. ONLY, - NO history/curriculum. Ready for agile, human-like 🤖? (Best with 🎧) 🔗 omniretarget.github.io 🎥 1/9

It's almost time for #CoRL 2025! A reminder that we're hosting the Data in Robotics workshop this Saturday Sept 27th. We have a packed schedule and are also attempting to livestream the event for those who can't attend in person.

Honored that our @RL_Conference paper won the Outstanding Paper Award on Empirical Reinforcement Learning Research! 📜Mitigating Suboptimality of Deterministic Policy Gradients in Complex Q-Functions 📎openreview.net/forum?id=H3jcT… Grateful to my advisors @JosephLim_AI and @ebiyik_!

At @RL_Conference🍁, I'm presenting a talk and a poster on Aug 6, Track 1: Reinforcement Learning Algorithms. We find that Deterministic Policy Gradient methods like TD3 often get stuck at local optima under complex Q-functions, and propose a novel actor architecture! 🧵

Do you work on robotics? Do you like robots? Then, visit Korea next year! We (@ryoo_michael @gupta_abhinav_ @SongShuran Haewon and more) are organizing CoRL 2025 in Seoul, Korea!! #CoRL @corl_conf #robotics
Michael Ryoo@ryoo_michael

I am extremely pleased to announce that CoRL 2025 will be in Seoul, Korea! The organizing team includes myself and @gupta_abhinav_ as general chairs, and @JosephLim_AI, @songshuran, and Hae-Won Park (KAIST) as program chairs.

I've been historically bearish on skill-based RL and @Jesse_Y_Zhang consistently shows me I'm probably wrong. Come check out EXTRACT at 1600 at @corl_conf (poster #11) to see him yank semantically meaningful skills out offline data by leveraging PTLMs. arxiv.org/abs/2406.17768

This work was guided by Jesse's co-advisor's @ebiyik_ and @JosephLim_AI, but I think we all agree that Jesse is effectively running his own little lab. If you're thinking about hiring a postdoc in the area of RL for robotics, Jesse comes a ton of insight and mentoring experience!

Well.. we won the best system paper award #RSS2023 @RoboticsSciSys !! @MinhoHeo’s talk can be found at: youtu.be/QXmcu9fVnak?t=… We (@MinhoHeo @doohyun22 @YoungwoonLee & I) gave quite a bit of effort into this talk. So, we hope you enjoy the talk and, of course, the project :)

At #RSS2023 this week w/ some of my (ex-)students from CLVR (@YoungwoonLee @MinhoHeo @doohyun22 @sungj1026 ). Excited to meet about topics on robot learning, RL, physical reasoning, long-horizon manipulation, etc. + Recruiting (int’l & domestic) students. Plz come and say hi!

Excited to present PATO: Policy Assisted TeleOperation, our recent work on scaling robot data collection! PATO uses a policy trained on prior data to assist the user during data collection, making teleop easier and even allows to teleop multiple robots simultaneously. 🧵👇
