Robot localization refers to the process of a robot determining its location in an environment usually represented by a map.
There are several ways robots can estimate their location in an environment, such as:
- Laser sensors
- Vision sensors
- Ultrasonic sensors
This capability is essential for autonomous mobile robots and vehicles because they would not be able to travel between their current location and a goal location without it.
Robot localization is the first fundamental step in robot navigation:
- Robot localization
- Path planning
- Map building and interpretation
Additionally, robotic localization is critical in obstacle avoidance and handling busy environments.
