URDF (Unified Robot Description Format)

URDF (Unified Robot Description Format) is an XML-based language used to represent a robot's physical structure and properties in robotics software. It details the robot's parts (links), how they connect (joints), and attributes like size, shape, and movement capabilities. This standardized format enables simulation, control, and visualization of robots within software environments, providing an accurate digital model. Essentially, URDF acts as a blueprint that describes a robot's anatomy, allowing software to understand and interact with it effectively for various tasks like design, testing, and operation.
