Abstract: A split control system for UAV incorporating auto pilot is disclosed. Control system comprises a real-time low-level main processor, and a non-real-time high-level co-processor. The co-processor computes desired body rate values and feeds them to the main processor which may be with latency. Main processor computes one or more motor control signals based on the desired body rate values. The main processor also executes a rate damping loop algorithm based on instantaneous body rate values to generate one or more motor control signals to maintain stability of the UAV even in events of latency in desired body rate values from the co-processor. Instantaneous body rate values are either obtained directly from sensors without any latency or obtained by main processor indirectly with negligible latency. Main processor acts as an intermediate between sensors and co-processor by collecting raw sensor data and feeding the data to co-processor.

Abstract: The present disclosure provides a multi-rotor Aerial Vehicle comprising at least five arms. Pairs of coaxial contra rotating rotors/propellers are configured on each arm defining a polygon. In the event of failure of any one of the rotors/propellers, a control system incorporating an autopilot, shuts off corresponding contra rotating rotor/propeller of the pair to maintain yaw stability thereby rendering the corresponding arm non-functional; and adjusts throttles of the coaxial contra rotating rotors/propellers of remaining functional arms to maintain tilt and lift stability of the Aerial Vehicle.

Abstract: A system and a method for estimating coverage area and viewing area for an Unmanned Aerial Vehicle 104 (UAV 104) is disclosed. It involves creating an operational map of a home location's area coverage 302 pertaining to a complex terrain based on no fly zone polygon data and elevation data, based on the information of the area coverage provided by a navigation unit. The map is created using multiple sample points and validating said sample points by checking whether or not they are at no fly zone or exceeding maximum AGL. Moreover, the operational map is drawn by using home location as a center point. Further, it involves determining and generating coverage area and viewing area of the UAV based on the operational map. It also discloses a feature of checking take-off suitability.
