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.

@leggedrobotics Thanks for this!
I want to start looking into off policy methods for humanoids and this is very useful 🙏🏼

This project is led by Gianluca Sabatini, supported by Chenhao Li @breadli428 and Marco Hutter @leggedrobotics. We thank Clemens Schwarke's implementation insights.
Check out the paper!

The implementation extends RSL-RL with same APIs, same training pipeline, same wrappers.
✅Swap the agent config, and you're running RSL-RL-SAC. Multi-GPU, RND, and symmetry augmentation are included out of the box.

This project focuses on understanding the performance gap between PPO and SAC in massively parallel robot learning.
While efforts like FlashSAC @hojoon_ai and FastSAC @younggyoseo explore separate development, RSL-RL-SAC is made to stay close to the widely used RSL-RL codebase.

On humanoid tasks, SAC actually outperforms PPO. Entropy-driven exploration pays off in dense reward settings.

By adapting SAC for massively parallel simulation in IsaacLab, we match PPO across quadruped locomotion tasks — with a single set of hyperparameters, NO reward retuning needed.

To make SAC work well, we crystallize four major factors that matter:
✅Right-sizing the action space
✅Treating timeouts as timeouts, not failures
✅Smoother targets via n-step returns
✅Starting exploration where it should

PPO has been the go-to algorithm for training robots in simulation. SAC is more sample-efficient in theory, but consistently fell short in practice. And while PPO thrives where data is cheap, it hits a hard wall when moving to real-robot learning.
🔥We set out to close that gap.

PPO has long dominated robot locomotion training in simulation. SAC, despite its sample efficiency, couldn't keep up.
We analyze why:

🔥Integrated into RSL-RL, our approach requires only minimal changes, making SAC a drop-in alternative out of the box. h

Advancing dexterous manipulation through scalable visual sim-to-real transfer.
We are excited to share our RSS paper, “ViserDex: Visual Sim-to-Real for Robust Dexterous In-hand Reorientation.”
