Abstract: A vertical take-off and landing (“VTOL”) unmanned aerial vehicle (“UAV”) system and a method of controlling the same, wherein such method controls the stability and maneuverability of the VTOL UAV by manipulating the speeds of the propellers at each rotor. The VTOL UAV includes a body with three extending arms, wherein each of such arms is aligned and fixed at a certain angle from a central axis passing through the body. Each extending arm is equipped with a rotor with propellers. The rotors are sufficient to control the yaw of the UAV, and there is no need for coaxial rotors or an extra servo-motor in order to control the yaw of the UAV, thus reducing the cost and the weight of the UAV.

Abstract: There is provided a system, method, and a computer program product that, when implemented, provides a user a notification about one or more road conditions. The system may include one or more sensors that may be configured to detect the presence and absence of one or more road markings, and a processing unit in operable communication with the one or more sensors configured to receive and process a plurality of sensor readings provided by the one or more sensors. A display in operable communication with the processing unit may be configured to display audio, visual, and audiovisual notification messages to a user.
