Robot Localization

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
  • GPS

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.
