Configuration Space

Definition

Configuration space is a mathematical concept that represents all possible states or configurations of a system, often used in robotics and motion planning. It allows for the analysis of how objects can move and interact within a given environment by considering their position and orientation in space. Understanding configuration space is essential for solving problems related to movement, collision detection, and pathfinding in various applications.
