Simultaneous Localization and Mapping , also known as SLAM, is the process of collecting
data from the physical world, with the help of numerous sensors installed in the
robot. Subsequently, This data is generated into maps for later navigation.  SLAM
makes  it easier for the robot to localize itself, interpret data through visual
points, build a map and use it to navigate simultaneously.

when a person tries to identify his way around an unknown place. The first step
is to look around to find familiar markers or signs. Once The person recognizes 
a familiar landmark, he  can figure out his whereabouts in relation to it. The more
that person observes the environment, the more landmarks will become familiar to
him and  he will begin to build a mental image, or map, of that place.  He may have
to navigate this certain environment several times before becoming familiar with
a previously unknown place. In a related way, a SLAM robot uses its sensors (Sonor,
laser or cameras) to map environment while figuring out its own location.

The popularity of the SLAM problem is correlated with the emergence of indoor mobile
robotics. The use of GPS has no room to bound the localization error for indoor 
usage, such as [**Telepresence**](https://sifsof.com/product-category/artificially-intelligent-robots/telepresence-robots/),
[**service **](https://sifsof.com/product-category/robots/service-robots/)and [**disinfection robots**](https://sifsof.com/product-category/disinfection-robots/).
Additionally, SLAM offers an appealing alternative to user-built maps, showing that
robot operation is approachable even in the absence of a purpose specification localization
infrastructure.
