Methods and apparatus to facilitate autonomous navigation of robotic devices

This invention describes an autonomous robot designed to navigate by analyzing images of its surroundings. It uses different specialized neural network models, each uniquely associated with a specific "region" of its environment. As the robot moves from one region to another, it switches to the corresponding neural network model to guide its movement. If an obstacle blocks its path, the robot can request a new route from a remote server, which provides new regions and their respective neural network models.
