Abstract: The subject matter discloses a mobile robot, comprising a body, one or more distance sensors mounted at the body, 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 one or more distance sensors, said rotating mechanism is configured to enable rotational movement of the one or more distance sensors and a processing module electrically coupled to the one or more distance sensors and to the rotating mechanism, said processing module is configured to process the distance measurements collected by the one or more distance sensors and compute resolutions in the distance measurements associated with multiple objects in the area, and to instruct the rotating mechanism to adjust a velocity of the rotational movement in case the resolution is lower than a minimal resolution threshold associated with an object in the area.
