The quest for a universal robot—one that can seamlessly switch between tasks, platforms, and environments—has long been the holy grail of robotics research. The paper “Green-VLA: Staged Vision-Language-Action Model for Generalist Robots” brings us closer to that vision with a revolutionary five-stage training framework that enables a single policy to control humanoids, mobile manipulators, and fixed-base robotic arms alike. The Problem: One Robot, Many Bodies Today’s robotic systems are typically specialists. A robotic arm in a factory excels at assembly but cannot navigate a warehouse. A mobile robot can move around but lacks fine manipulation skills. Training a separate AI for each type of robot is expensive, time-consuming, and fundamentally limits scalability. ...
