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.

A Balanced Data Diet: Addressing the Exploration Bottleneck in Mega-Scale RL for Robot Control

The paper introduces Success Guided Sampling (SGS), an adaptive sampler that focuses reinforcement learning on task configurations near the policy’s current frontier, thereby reducing wasted experience in massively parallel simulation. SGS enables large‑scale RL to solve complex quadruped locomotion and contact‑rich assembly tasks that previous methods could not, using up to one million parallel environments. The authors also distill the learned policies into RGB‑based models that transfer zero‑shot to real‑world assembly tasks.

EXPO-FT: Sample-Efficient Reinforcement Learning Finetuning for Vision-Language-Action Models

EXPO-FT is a system that enables stable, sample‑efficient reinforcement learning fine‑tuning of pretrained Vision‑Language‑Action (VLA) policies. It achieves perfect success on a range of manipulation tasks—such as routing string lights, striking a pool ball, and inserting a flower into a wine bottle—using only about 19.1 minutes of online robot data. The approach outperforms both RL-from-scratch and existing VLA fine‑tuning methods, and the authors provide an open‑source codebase to support wider adoption.
