Generalizable Robotic Insertion with World Models

Robotic assembly in high-mixture settings requires adaptable systems that can handle diverse parts, yet current approaches typically rely on policies specialized to each insertion task. Although this can reach high success rates, it makes the process of deploying systems for new problems tedious and time consuming. We...

FACT: Failure-Aware Causal Training for World-Action Models

FACT is introduced, a causal World-Action Model that predicts future video and task progress conditioned on the executed action, and allows failure rollouts to supervise action consequences, turning bad actions into valid future targets rather than being discarded.

RoboTALES: Learning Reasoning-Guided Robot Policies via Task-Aligned Simulated Futures

This work proposes RoboTALES, a single-stage framework that learns task-aligned simulated futures and uses them to train robot policies and introduces two key innovations: a hierarchical LLM-based planner that breaks complex tasks into a sequence of subgoals to guide the model's imagination and a VLM-based critic that...
