Has visual fidelity outpaced dynamic fidelity in tactile simulation for sim-to-real transfer of policies?

Introducing HydroShear 🏄‍♂️ : a hydroelastic tactile shear simulation for training zero-shot sim-to-real tactile policies in contact-rich tasks where fingertip force and shear matter most!

Introducing Cosmos 3: Our latest frontier model for Physical AI

Cosmos 3 is the world’s first fully open omnimodel with native vision reasoning, world and action generation.

Today we’re releasing Super (32B) and Nano (8B) variants.

🥳HydroShear got accepted to RSS 2026! Looking forward to the Vitruvian kangaroo t-shirt!

We've open-sourced our code for tactile sim-to-real RL:

Robot memory methods are growing fast, but systematic evaluation is largely lacking. 📉

Introducing RoboMME: a new benchmark for memory-augmented robotic manipulation! 🤖🧠

Featuring 16 tasks across temporal, spatial, object, and procedural memory

high fidelity tactile simulation with shear(!!) to train sim-to-real RL policies

years ago I was less bullish on tactile simulation so we doubled down on SSL with just real data to build Sparsh models

now we can revist co-training on sim + real data

Thanks to my awesome co-lead @dangan1693 and all the amazing guidance and support from our team @mukadammh, Alice Wu, Bernadette Bucher, Manikantan Nambi, and @NimaFazeli7!
