Are we experiencing a GPT moment in robotics? Our MolmoSpaces benchmark seems to suggest so. Check out @omarrayyann's thread to see the details ๐Ÿ‘‡

A solid step toward humanoid loco-manip, super cool!
Meet FetchMan: a vision-based humanoid policy trained entirely in simulation that transfers zero-shot to diverse real-world scenes and objects. Simulation has produced impressive locomotion policies that transfer to the real world. We wanted to see how far the same recipe goes for vision-based loco-manipulation. More below๐Ÿงต

Learning mobile manipulation is hard because collecting data for mobile manipulation is hard. But seems like @omarrayyann has found a promising way to crack this problem!

We will be in the #RSS2026 poster session at 6:30 PM โ€“ stop by with all of your questions!
MolmoSpaces provides singular scale and diversity. We built a benchmark that puts that scale to use. MolmoSpaces-Bench evaluates zero-shot policies across thousands of environments previously unseen to them under systematic variation, providing insights that go beyond a success rate % More Below:

Robots are the bottleneck in scaling robotics, and learning from human video promises to solve it. But how can chaotic human data ever measure up to sanitized, lab-made teleoperation data? Introducing Do as I Do: establishing a much needed correspondence between human videos and dexterous robot data. Some fun insights below: ๐Ÿงต

Robotics is still data starved. Collecting high-quality robot demonstrations remains brutally slow and expensive. Introducing COBALT: A cloud-native teleoperation platform designed for large-scale robot learning. We are democratizing data collection by leveraging the hardware everyone already owns: the smartphone All you need is to download an app (today)! Read on for more!

Just merged an amazing contribution by @omarrayyann to mjlab's viser viewer: checkpoint hot-swapping! You can now browse and load any checkpoint mid-session without restarting and it works with local checkpoints and W&B runs.

Benchmarking, evaluating, and developing robotics code is difficult, and part of this is because no simulator really reflects the diversity and scale of real embodiments. Enter MolmoSpaces from AI2: a massive open ecosystem with a range of 230,000 handcrafted and procedurally-generated home environments, including 48,000 manipulable objects. Crucially, MolmoSpaces provides simulation environments which work for both navigation and manipulation. We talked to the team: @YejinKim4, @omarrayyann, and Max Argus, to tell us more. Watch Episode 69 of RoboPapers, with @micoolcho and @DJiafei, now!

Jensen approves! Hercules efforts from @YejinKim4 @omarrayyann, Max Argus & team! This has a decent chance of becoming a super important benchmark fo robotics going forward. Check out this @RoboPapers episode with the MolmoSpaces folks.

MolmoSpaces leaderboard is now open for submissions! When we created this benchmark for zero-shot real-to-sim eval in diverse homes, we didnโ€™t expect things to heat up so quickly. But it did, thanks to @jang_yoel and team at GEAR toppling PI to take the crown on task-general category. Congrats ๐ŸŽ‰ You can evaluate and submit your model to this leaderboard: molmospaces.allen.ai/leaderbโ€ฆ

Also check out MolmoSpaces-Bench from @omarrayyann! Our contact-anchored policies (CAPs) perform well zero-shot across diverse environments and objects. Omar is the rockstar behind our sim env for CAP, enabling us to train and evaluate multiple models in a day.
Replying to @omarrayyann
Itโ€™s hard to find true zero-shot end-to-end policies โ€“ ones that work without any fine-tuning in fully novel, simulated environments, even for single tasks! We test two policy families, the ฯ€ family from @physical_int and the recent Contact-Anchored Policies (CAP) from NYU & UCB. On all our tasks, we are making steady progress โ€“ but we are nowhere close to saturation yet.

How general are your general robotic policies? Today, we're releasing MolmoScenes-Bench to help explore this question. You can spin up ~1k envs in ~700 unique simulated homes and within hours find out how well your zero-shot policy generalizes to these unseen scenes ๐Ÿงต
MolmoSpaces provides singular scale and diversity. We built a benchmark that puts that scale to use. MolmoSpaces-Bench evaluates zero-shot policies across thousands of environments previously unseen to them under systematic variation, providing insights that go beyond a success rate % More Below:

okay, actually yes
interesting. We also observed that contact predictions help locomotion control. I wonder if this would be general for learning-based control if we first predict the contacts, e.g., for VLA/WMs.

Omar is the mastermind of EgoGym โ€“ our sim eval-only benchmark that we hillclimbed to improve in the real world. That it was even possible was surprising to me, but it turns out when your robot is trained on diverse data sim is just another new environment.
Very excited to release Contact-Anchored Policies (CAP) ๐Ÿงข today! Check out this thread for more details on that and on our in-the-loop simulation evaluations:

We don't need the name of an object to pick it up; we simply need to know where it is and what it looks like. Introducing Contact-Anchored Policies (CAPs): instead of language, we explicitly condition on contacts. Our policy learns object pickup with only 16 hours of data! ๐Ÿงต
