Can a humanoid learn faster and better by seeing less? We train a small model to predict the policy's next steps, and show the policy only the terrain there. Together, they learn to cross gaps, stairs, drops and boxes. 🌐 leggedrobotics.github.io/wat… 📄 arxiv.org/abs/2610.29612

Watch Your Step: Anticipated Perception for Humanoid Locomotion

Predict where the feet will land, and show the policy only the terrain there. Zero-shot on a Unitree G1.

What does a humanoid need to look at to cross challenging terrain? People only look around their next few planned steps. So we showed a humanoid only that. Watch Your Step: Anticipated Perception for Humanoid Locomotion 🌐 leggedrobotics.github.io/wat… 📄 arxiv.org/abs/2610.29612

In our latest work at @corl_conf, we introduce Quadrupedal World Model: a single morphology-conditioned dynamics model, where policies are trained entirely in imagination. We found generalization emerges by conditioning the dynamics, not the policy. 🔗modanesh.github.io/papers/qw…

What if one world model could control many different robots? 🤖🌍 That's QWM. In this 2 minutes video we show keypoints about QWM: learning across heterogeneous quadrupeds, and transferring zero-shot to unseen morphologies. No fine-tuning. No warm-up. No retraining. Let's talk it further at CoRL 🥳

LP-ACRL removes the need to predefine task difficulty. It measures task-wise learning progress from episodic-reward changes, then uses a softmax to shift sampling toward the current learning frontier, where tasks show stronger positive competence gains at that stage.

After teacher–student distillation, a single policy transfers to ANYmal D and achieves: • 3.0 m/s on flat terrain • 2.5 m/s on challenging terrain • Up to 3.0 rad/s angular velocity across all tested terrains

Scaling Rough Terrain Locomotion With Automatic Curriculum Reinforcement Learning Authors: Ziming Li @ZimingLi97, Chenhao Li @breadli428, Marco Hutter Published in: IEEE Robotics and Automation Letters ( Volume: 11, Issue: 8, August 2026) ieeexplore.ieee.org/document…

We achieved high-speed rough-terrain locomotion on ANYmal with an automatic curriculum. LP-ACRL automatically samples terrain types, levels, and velocity commands at the correct time based on policy performance, without predefining an order. 🔗sites.google.com/view/lp-acr… 🧵RAL 2026

Real-world locomotion does not follow a single easy-to-hard axis. Terrain type and geometry compound with linear and angular velocity specifications. In our scaled setup, their Cartesian product forms 600 tasks, making a manually ordered curriculum impossible.

VLMs don't understand a robot's body. How can a robot learn from its failures without retraining? PragmaBot: online in-context learning from real-world experience. The robot reflects on failures, stores lessons in memory, and retrieves them for new tasks. RA-L · #IROS2026

How much memory belongs in the context? 5 random memories: 17% first-action accuracy on unseen tasks. Entire memory in the prompt: 74%, at 7.5x the tokens. Top-k relevant via RAG: 89%. Relevant context beats more context. As memory grows, what should a robot forget?

We’re open-sourcing the dataset and the full data pipeline to make this resource accessible to the community and hopefully enable new directions in learning-based robotics.
