RL can assist robot data collection during demonstrations through a technique called Data Inoculation, improving data quality for both behavior cloning and RL, as shown in a new paper on stacking cubes.
TAD introduces Trajectory-only Adversarial Distillation, which improves vision-language-action policies using only a fixed bank of teacher trajectories—no teacher action scores or task rewards—via a discriminator providing on-policy rewards, boosting OpenVLA-OFT success rates substantially while trailing white-box on-policy distillation.
RynnWorld-Latent is a cross-embodiment video world model that uses 3D-grounded latent actions as a shared conditioning interface, enabling joint pretraining on human videos, robot demonstrations, and simulation rollouts to generate synthetic data that improves robot policy performance on LIBERO and real-world platforms.

A new paper, 'Split the Differences, Pool the Rest: Provably Efficient Multi-Objective Imitation Learning', introduces MA-BC, which pools expert demonstrations only where observed actions do not disagree, and provides upper and lower bounds on sample complexity for learning from experts with differing objectives.
Pantheon describes how it built a highly diverse Universal Manipulation Interface (UMI) robotics dataset in eight weeks with 90 operators, custom in-house hardware, and VLM-based freeform annotation, producing over 1 million unique tasks at $10/hour and releasing a 100-hour annotated sample.
MimicX introduces policy-in-the-loop supervision refinement for video-driven humanoid motion tracking, enabling robots to execute human motions (tennis, football juggling, dance, kung fu, parkour) captured from ordinary video demonstrations, including in collision scenes.
