AI, Physical AI, World Models, VLA, VLM, and Other Terms We Should Stop Mixing Together

The text explores the increasingly crowded landscape of robotics AI terminology, clarifying distinctions between related but distinct concepts such as Physical AI, World Models, Vision-Language Models (VLMs), Vision-Language-Action Models (VLAs), Robot Foundation Models, and Digital Twins. Physical AI refers to systems where AI outputs impact the physical world through robots and machines, requiring careful system-level reasoning to ensure safety and effectiveness. World Models predict environmental evolution, while World Foundation Models aim to generalize across various scenarios and applications. VLMs connect visual data with language but do not perform actions, whereas VLAs integrate perception and language with robotic action generation. Robot Foundation Models support diverse robotic behaviors across tasks and environments, although they are not complete systems. Digital Twins, in contrast, are virtual representations of specific real-world systems. The text emphasizes the importance of correctly using these terms as they significantly impact architecture, data collection, evaluation, safety, deployment, and product positioning in the field of robotics and autonomous systems.
