SHADOW CASTING DRONE

The present invention relates to systems for protecting against sun's damaging rays, and against unwanted onlookers like drones. The systems comprise a drone and a covering member attached to the drone. In one aspect, a Flight Control System, FCS, flies the drone in a selected spot. In one embodiment, the covering member acts like an overhead covering, and a measuring device provides the FCS information for flying the drone on a holding position over a stationary user. In another embodiment, a measuring device enables the FCS to fly the drone over a non-stationary user and to tracking him. Further, the FCS adjusts the drone position with respect to the position of either the sun or a detected drone in the sky. In another embodiment, a radio control, transmitter receiver, pair is used to communicate user's requests to the FCS. One request may be to turn on the motors.
