odometryand
Odometry and is a term that describes the process of using a robot's own sensors to estimate its position and orientation over time. This is commonly achieved by tracking the movement of the robot's wheels or other actuators. By measuring the distance each wheel has rotated and knowing the wheel's diameter and the robot's wheelbase, odometry can calculate the change in the robot's position and heading. This allows the robot to build a map of its environment or navigate to a specific location.
However, odometry is not a perfect system. Errors can accumulate over time due to factors such as
