<![CDATA[In this paper, the importance of odor localization is explained. The researchers that investigated the experiments and applications of odor localization using static sensors, mobile sensors (that were integrated in single robot, multi robot, and swarm robot) are described. However, there are some difficulties faced by the researchers in applying the mobile robots in the real situation, such as: the speed of mobile robots are not as fast as the odor patches transporting and the use of more than one sensor in mobile robot can make noises or errors. In the future, the plume finding in the uncertain environment and the challenges mentioned above will be the authorsâ consideration.]]>
