Here is what it feels to be an autoregressive LLM. I show you a question, and ask you to write an answer. You write the first word, and then I zap you with a taser so that you forget what you just did. 1/2

Teleoperation is slow, expensive, and difficult to scale. So how can we train our robots instead? Introducing X-Sim: a real-to-sim-to-real framework that trains image-based policies 1) learned entirely in simulation 2) using rewards from human videos. portal-cornell.github.io/X-Sim

Huge thanks to my co-lead Prithwish Dan, collaborators Angela Chao, Edward Duan & Maximus Pace, and co-advisors Wei-Chiu Ma Sanjiban Choudhury! Thrilled that our X-Sim paper received Best Paper (Runner-Up) at the EgoAct Workshop Robotics: Science and Systems β€” winning a cool pair of Meta Ray-Bans! 😎

We released COLMAP v3.12, which adds long-awaited end-to-end support for multi-camera rigs and 360Β° panoramas πŸ‘€ COLMAP just got better at handling your robotics, AR/VR, or 360 data - try it and let us know! github.com/colmap/colmap/… Kudos to Johannes & team for this great work πŸš€

One amusing takeaway from doing RL in these massively parallelized sim environments is that reward engineering matters more so than ever. A small detail in reward function could make a huge difference: with 10k+ parallel threads to explore in, the policy Will exploit any caveat
