Perception enables robotics, allowing interaction with the surrounding environment.
Sometimes just looking at the faced scenario is not enough, robots could require to map information needed for navigation.
Localization: the algorithmic response to the robots’ question: “where am I?”
Given an environment representation, a localization system, and a goal to reach, the optimal path must be computed.
Reaching the desired location could require the more different robotic locomotion systems: wheels, trucks, legs…
To change the world, you must manipulate it.
