What is exploration?

Exploration can be defined as the act of moving through an unknown environment while building a map that can be used for subsequent navigation.

Why exploration?

Humans explore their environments visually and know the places (like corridors, halls, walls, staircases etc) and also connect these regions for future reference. Robots are majorly used in places where humans cannot reach. Hence they should have the first know the environment like humans, by building map and to move around to do certain tasks. Example: Mars Rovers, Rescue robots etc.

Previous Algorithms:

  1. Simulations using “blue print” of floor plans.
  2. Wall following algorithms, which fails for large open space.

Types of exploration:

  1. Frontier based exploration
  2. Entropy based Exploration
