Developing algorithms that enable robots to see and interpret the world (e.g., using vision and LiDAR). Research in Simultaneous Localization and Mapping (SLAM) and 3D scene reconstruction.
Detailed Explanation
This chunk discusses the importance of robot perception, which is the ability of robots to gather information about their environment through sensors. Algorithms based on machine vision, like camera systems or LiDAR (a laser-based sensing technology), help robots form a picture of their surroundings. Simultaneous Localization and Mapping (SLAM) enables robots to navigate new environments while mapping their surroundings in real time, ensuring they know where they are and what is around them.
Examples & Analogies
Imagine you are in a dark room and trying to find your way around by feeling the walls with your hands. As you move, you're creating a mental map of the room and noting where you are. Similarly, robots use their sensors to interpret the world and build a map as they move.
