## Summary

dex-retargeting analyzes motion retargeting from human hands to robotic dexterous hands, using a Huber loss on wrist-to-fingertip bone vectors as the objective for per-frame numerical optimization. DexPilot builds on this method by adding grasp detection, projected targets, and temporal low-pass filtering, with the Allegro and Shadow hands converging per frame at millisecond-level speed.
