DexMimic: A Generalist Dexterous Hand-Object Tracking Policy via Value-Guided Reset Allocation

Read the original on arXiv AI →

DexMimic is a generalist dexterous hand‑object tracking policy trained across diverse human hand‑object interaction trajectories. It uses Value‑Guided Reset Allocation to adapt the initialization distribution, prioritizing difficult phases and selecting reset states that maximize expected tracking returns. The authors present a benchmark for training, fine‑tuning, and generalization, demonstrating improved tracking success, training efficiency, faster fine‑tuning, and potential zero‑shot generalization to unseen trajectories and objects, and validate the approach on a real‑world dexterous manipulation platform.

Dex-One2Many: Learning Dexterous Manipulation from a Single Human Demonstration

Dex-One2Many introduces a real-to-sim-to-real framework that learns a generalizable dexterous manipulation policy from a single human video. By abstracting the video into sequential scene graphs, the method guides reinforcement learning with dense rewards and diverse reset states, enabling efficient exploration while preserving broad generalizability. Trained entirely in simulation, Dex-One2Many achieves zero‑shot transfer to a real multi‑fingered hand and outperforms baselines by 6.5% on seen configurations and 71% on unseen scenarios across five tool‑use and manipulation tasks.

Learning Adaptable Dexterous Skills via Hybrid Dexterous Mimicking

AdaDex is a goal‑conditioned reinforcement learning framework that transforms a short hand‑object trajectory—captured via mocap or in‑the‑wild RGB(D) video—into an adaptable dexterous skill. It trains a shared policy on two parallel environment populations: motion‑tracking environments that embed human priors and generalization environments that enforce robustness to noisy states and goals. The resulting policies achieve diverse, functional dexterous behaviors such as grasping, re‑posing, in‑hand reorientation, and dynamic throw‑and‑catch, outperforming baselines in generalization and demonstrating transfer from simulation to the real world.

Dexterous Point Policy: Learning Point-based Dexterous Hand Policies from Human Demonstrations

arXiv:2606. 10614v1 Announce Type: cross Abstract: Robotic foundation models pre-trained on human demonstration videos have shown promise, but a significant embodiment gap remains when the resulting policies are deployed on real robots.

DexPIE: Stable Dexterous Policy Improvement from Real-World Experience

DexPIE is a post‑training framework that improves dexterous manipulation policies using real‑world experience. It introduces a dexterous‑hand‑adapted intervention system and multi‑stage DAgger‑style data collection to enhance exploration, aligns training and inference to reduce distribution shift, and conditions the policy on a continuous optimality indicator for fine‑grained data quality use. In three real‑world tasks, DexPIE boosts success rates by 37.3% over a demonstration‑based baseline, outperforming all other methods and showing stronger robustness.
