One world, one policy.
MorphMimic shares a morphology-conditioned world model and policy across #Unitree G1, #AgiBot X2 Ultra, and #Booster T2—from the same dance in MuJoCo to a live browser demo and Unitree G1 hardware, with more to come. Code and report at lzyang2000.github.io/morphmi…
Huge thanks to the SuperMimic team for the inspiration!
What a great work, ported into mjlab as a patch and can do below, with shadow on, 4096 env, 640x480. Code at github.com/lzyang2000/mjlab_…
The main goal is to open-source to the community to facilitate further research. Will continue to improve the pipeline. I thought if I were to open-source it should be more than just reimplement SuperMimic, so here we are. This will not be submitted to venue in its current form.

And yes this is done solely after SuperMimic came out, saw an interview of @ZhongyuLi4 a few days before, where he talked about that if every embodiment is trained by itself then it’s difficult to scale. When I was reading SuperMimic the idea came back to me - coupled with me thinking of latent space recently - lead to this project

With @JayHe748646 @KehanWen170077 @leggedrobotics , we push humanoid mobility to next frontier.
Achieved by a generalist contact planner + a generalist tracker + a generalized neural mapping, warmstarted from few human data.

We found a way to scale humanoid control that reduces GPU-hours by more than 1000×.
Across 129,514 motions, SuperMimic surpasses the state of the art (128 GPUs, 7 days) with 1 GPU in 3 hours.

VoxelCraft, built with Qwen3.8-Flash-Next in Codex: 11 hours, 8 Qwen agents, 100.74 million tokens processed, and 881,597 output tokens.

This was done with Strata on 5070ti +64G. Thanks to Nico1221 at github.com/Niko1221/Strata
And we did this before Astra :)
Natural language driven with a harness, fully autonomous
Walking, handling objects and getting back up. All with one controller.
Gary Yang, Junheng Li and Aaron Ames, the PAC-MAN authors we featured in #01, return to our series as part of the HANDOFF team.
BONES data in Research #04
When you reach for an object, you think about where your hand needs to go. The rest of your body coordinates in the background.
HANDOFF brings this idea to humanoid control. The planning system uses text instructions and visual observations to set hand targets, walking speed, and body height. One controller coordinates the robot’s movement.
The team distilled motion-tracking, walking, and fall-recovery teachers into a single policy. The motion-tracking teacher learned from human motions in BONES-SEED, retargeted to the robot.
The authors demonstrated different object tasks on a real G1 without task-specific controller fine-tuning.
Congratulations to @lzyang2000, @Junheng_Li1, Nehar Poddar, Yiling Hou, @giohuh_, Robert Griffin, @georgiagkioxari and Aaron Ames!

Can a humanoid be your badminton buddy, learning from just 30 min of human motion data? Humanoid Badminton 🏸, accepted at #CoRL2026, learns diverse racket skills with a single policy, enabling natural whole-body motion and real-world multi-skill rallies with forehand, backhand, and highly dynamic jump returns.

Glad to see dodgeball becoming popular
releasing orcs, a toolkit to post-train humanoid whole-body controllers for tasks.

I'm excited to release mjbatch, a simple tool that lets you step thousands of MuJoCo simulations in parallel on your CPU, all from the comfort of Python!

To show how far this primitive can take you, I built some fun, self-contained examples with it 👇
