Abstract: The subject matter discloses a mobile robot configured to map an area, comprising a body, two or more distance sensors, configured to collect distance measurements between the mobile robot and objects in the area, a rotating mechanism mechanically coupled to the body and to the two or more distance sensors, said rotating mechanism is configured to enable rotational movement of the two or more distance sensors and a processing module electrically coupled to the two or more distance sensors and to the rotating mechanism. The processing module is configured to process the distance measurements collected by the two or more distance sensors and to instruct the rotating mechanism to adjust a velocity of the rotational movement, said velocity is adjusted according to the distance measurements collected by the two or more distance sensors.
