Reflex: Visually Grounded Reactive Humanoid Control

arXiv 2026 16.3 method

TLDR

A three-stage framework for egocentric visual reactive whole-body humanoid control, demonstrated by catching thrown boxes in simulation.

Reasoning

The paper presents a well-structured decomposition of visual reactive control with clear training signals and simulation results. However, it lacks real-world validation, and the core contribution is not framed as a generative or interactive world model, making relevance to world-model keywords low.
