Abstract: A multi-rotor Aerial Vehicle with least rotors/propellers and having single arm failure redundancy is disclosed. The AV comprises at least five arms with at least one arm having a co-axial pair of contra rotating rotors/propellers. To maintain yaw stability under normal conditions, half of rotors/propellers are rotated in one direction and other half in opposite direction. In the event of failure of any one of the rotors/propellers located adjacent to the pair of contra rotating rotors/propellers, the one propeller/rotor out of the contra rotating rotor/propeller that is rotating opposite to the failed rotor/propeller is shut off. In the event of failure of a rotor/propeller belonging to contra rotating rotors/propellers, other rotor/propeller of the pair is shut off. In the event of failure of any one of rotors/propellers not adjacent to contra rotating rotors/propellers, the RPMs of other rotors/propellers is adjusted to maintain stability and navigate the Aerial Vehicle.

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: A fixed-wing VTOL hybrid UAV is disclosed comprising: a central frame 104; a pair of quick lockable fixed-wings 102 comprising right wing 102-2 and left wing 102-1 that lock with each other over the central frame; and four electrically operated rotors 108 in downward facing configuration attached to fixed-wings with help of rotor-blade arms 110. Arms 110 are pivotally fixed to wings 102 so that arms 110 are movable between a working position in which arms 110 are oriented parallel to central frame 104, and a storage position in which arms 110 are aligned with wings 102. Central frame 104 is a thin rod and works as fuselage. Drivers and control modules are fitted in wings 102. UAV includes rudders attached to arms at 45 degrees for maneuvering UAV for yaw and a secondary roll response. UAV includes two landing gears 106 attached to each end of central frame.

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: The present disclosure relates to generating a single vertex list/point-cloud list of an object for rendering the object in different complexity levels. The generated single vertex list comprises a large number of points obtained from external surfaces of the real-time object for detailed 3D representation and the list is updated with new batches of received point cloud vertices. The points are rendered from the single vertex list based on the correlation between zoom level and point retention factor. A scene's zoom/scaling level is altered by changing the distance of a camera to the objects represented by the rendered point cloud.

Snap levers 200 are located such that the two snap levers can be moved together by a single thumb or finger to the released positions. A sheet shaped planar biasing device 300 for biasing snap levers 200 towards the locked position is provided, which includes two generally U-shaped cut-outs defining cantilever springs in contact with the snap levers 200.

Abstract: An improved propeller system is disclosed, including at least one resilient component configured with a mounting arrangement of a propeller of the propeller system. The resilient component is made of a resilient material that allows the propeller to tilt about a tethering axis under conditions of differential lift force on blades of the propeller under an advancing condition and a retreating condition. The resilient component includes a pair of cutouts for locating inserts made of a rigid material and positioned with a longitudinal axis of the inserts oriented in radial direction. The orientation of the inserts results in a radially oriented line contact between the propeller and the inserts to ensure that tilting of the propeller is about longitudinal axis of the inserts, defining the tethering axis of the propeller system.
