1.7× faster inverse kinematics in pure Python, GPU-accelerated! Fully open-source and built for scale [📍Bookmark for later] PyRoki, a modular toolkit for robot kinematic optimization, supporting - inverse kinematics - trajectory optimization, and - motion retargeting. Built for flexibility, but also fast: ✅ Runs on CPU, GPU, and TPU ✅ Outperforms cuRobo in speed, success rate, and accuracy ✅ Fully in Python, easy to integrate and extend Whether you’re working with industrial arms, simulation environments, or humanoids, PyRoki is designed to fit your stack and scale with your hardware. Thank you, Chung Min Kim, for sharing!! Website: Code: Paper: This one’s for researchers, builders, and anyone tired of debugging their IK stack.

Video2Humanoid. Still trouble with bad retargeted humanoid motions? Humanoids now are Easy to track any video using our new Neural Motion Retargeting (NMR) Method. Optimization-based motion retargeting methods like IK and GMR are solving a non-convex problem frame by frame, which makes them sensitive to initialization, hard to tune, and prone to poor local minima. The result is familiar: joint discontinuities, self-collisions, and unstable foot contact. Our solution is simple but effective : instead of optimizing each frame independently, learn the mapping between human motion and robot motion as a distribution via networks. 📊Results on Unitree G1 - 0 joint jumps - 54% fewer self-collision frames - 61% fewer joint limit violations - Faster convergence for downstream control policy training NMR turns motion retargeting from a fragile optimization problem into a learned, scalable pipeline for more stable humanoid motion. please visit for more visualization results. opensource:

Spatial optimization has applications in nearly every field but it's underutilized. In 2026, I'm working on open source and lightning-fast tools to make spatial optimization accessible. Shown: interactively solving a "location-allocation" problem in an app with instant results.
