Vision-language-action models, often abbreviated as VLA models, are artificial intelligence systems that integrate three core capabilities: visual perception, natural language understanding, and physical action. Unlike traditional robotic controllers that rely on preprogrammed rules or narrow sensory inputs, VLA models interpret what they see, understand what they are told, and decide how to act in real time. This tri-modal integration allows robots to operate in open-ended, human-centered environments where uncertainty and variability are the norm. At a high level, these models connect camera inputs to semantic understanding and motor outputs. A robot can observe a cluttered table, comprehend a spoken instruction…
