Geometric Models

Definition

Geometric models are mathematical representations that use geometric shapes and forms to describe and analyze physical objects, spaces, or environments. They are essential in autonomous robotics for enabling robots to understand their surroundings, make decisions based on spatial relationships, and plan movements. These models facilitate a structured approach to navigating complex environments and support decision-making processes in robotic systems.
