If you have a log from real experiments, check it. The gyroscope on G1 saturated at 8.72 rad/s, which is 500 degrees per second. This is an extremely small value. Once the gyro saturated, the fused orientation also becomes incorrect.

Stein’s lemma originally formulated for Gaussian distributions applies more generally to arbitrary continuous exponential families. Allow to derive identities between raw moments for polynomial exponential families. tinyurl.com/SteinLemmaEF

Probably nothing, but multiple devices recorded video of a venue, then sent that to the @AukiNetwork's growing number of community nodes, that then collaborated to stitch it all together into this 3D map of the venue... Collaborative data capture. Collaborative reconstruction.

🤖What if you want to train rough terrain humanoid locomotion but have only flat terrain demonstrations? ⛳️In ConsMimic, we introduce a principled pipeline to learn stylistic motions from demonstrations that may not align with task objectives. See you @corl_conf in Seoul!

Excited to share our #CoRL2025 paper: Constrained Style Learning from Imperfect Demonstrations under Task Optimality. We introduce ConsMimic, optimizing a style-imitation objective with near-optimal performance constraints. 🔗 sites.google.com/view/consmimic 📄 arxiv.org/abs/2507.09371…
