Explain the navigation stack.

Question

Accepted Answer

The navigation stack is a collection of software components that work together to enable a robot to navigate autonomously in its environment.

The navigation stack typically includes components such as localization, mapping, path planning, and obstacle avoidance.
Localization is the process of determining the robot's position and orientation in the environment.
Mapping involves creating a map of the environment using sensor data.
Path planning calculates a safe and efficient path for the robot to follow.
Obstacle avoidance helps the robot navigate around obstacles in its path.
The navigation stack relies on sensor data such as lidar, cameras, and wheel encoders to make decisions.
An example of a popular navigation stack in robotics is the ROS Navigation Stack.
