The Core Challenge
The greatest hurdle in robotics isn't movement; it's the computational paradox of building a map while simultaneously using that map to find your way.
The SLAM Paradox
The Mutual Dependency at the Heart of SLAM
This section introduces the core paradox of simultaneous localization and mapping, framing it as a circular dependency problem in probabilistic robotics.
