Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. Robot navigation includes exploration, mapping, localization, path planning and path execution

Navigation includes:

  • exploration: the strategy that guides the robot to select the next direction to go
  • mapping: the construction of a spatial representation by using the sensory information perceived.
  • localization: the strategy to estimate the robot position within the spatial map
  • path planning: the strategy to find a path towards a goal location being optimal or not
  • path execution: where motor actions are determined and adapted to environmental changes.
