Vision-Language-Action (VLA) Concepts

This chapter introduces the core concepts behind Vision-Language-Action (VLA) systems.

What are VLA Systems?​

VLA systems aim to enable robots to understand and execute tasks based on both visual perception of their environment and natural language instructions. They bridge the gap between high-level human commands and low-level robot control.

Key Components​

  • Vision Models: For processing camera feeds to understand the environment (object detection, segmentation, pose estimation).
  • Language Models: For interpreting natural language instructions and translating them into a robot-understandable format.
  • Grounding: The process of connecting symbolic representations (from language) to real-world perceptions (from vision).
  • Action Generation: Translating grounded understanding into a sequence of robot actions.
