Navigation

Definition

Navigation refers to the process of determining one's position and planning a route to reach a specific destination, particularly in relation to robots and their operational environments. This concept is crucial for robots to understand their surroundings and make informed decisions about movement and task execution, enabling them to effectively operate in various applications, utilize advanced perception systems, and traverse challenging environments such as outer space or underwater.
