It is a range up to which a robot can view its surroundings. The area of visibility of a robot is usually assumed to be circular in which the robot is located at the center. This circle is known as the circle of visibility and the radius is known as the visibility radius.

Abstract
Swarm of mobile robots is actually a large number of small robots imitating the behavior of social insects that perform certain tasks in a group. This chapter considers the problem of area coverage by a swarm of mobile robots. Initially, the robots occupy random positions in a target area. The objective is to physically cover/scan each accessible location of that area by at least one robot of the swarm. After discussing, in brief, different models and their challenges this chapter summarizes the research works carried out to solve this problem. The existing literature is classified into two categories, namely, team based approach and individual approach. The pros and cons of both the approaches are indicated and finally a comparative study of the addressed works in terms of computational model, synchrony, characteristics of robots, etc. is presented.
