Abstract: The present disclosure relates to a control system for a retractable belly mounted payload in an Aerial vehicle for retraction, pan and tilt movements of the payload, comprising a first mechanism to rotate the payload about a vertically oriented first axis for pan movement of the payload, and a second mechanism to rotate the payload about a horizontally oriented second axis, wherein rotation of the payload about the second axis provides movement of the payload between a retracted position within belly of the Aerial Vehicle and a deployed position out of the belly of the Aerial Vehicle, as well as tilt movement of the payload in its deployed position. First mechanism is driven by a servo through a set of gears or pulley-belt mechanism, and second mechanism is driven by a directly connected servo connected to the payload. Both the servos rotate along with payload during pan movement.

Abstract: A method for capturing images of large target area using a single low FOV high resolution camera mounted on an Aerial Vehicle for 3D reconstruction is disclosed. The camera captures sets of images consisting of a nadir image a plurality of oblique images at predefined waypoints or as the Aerial Vehicle travels along a flight path. Oblique images are captured in two perpendicular directions by tilting camera about a single tilt axis at one time thereby preventing bidirectional distortion of objects in images. Further, first direction and second direction define a quadrant of area below the Aerial Vehicle. Oblique images along two perpendicular directions are captured either by using roll and pitch axes, or by using a single tilt axis and a pan axis of camera control mechanism wherein using pan axis the single tilt axis is reoriented in a perpendicular orientation to capture oblique images in perpendicular direction.

Abstract: The present disclosure pertains to non-planar frame structure of a multi-rotor unmanned aerial vehicle (UAV). Aspects of the present disclosure provide frame structure of a UAV that includes at least two rods 102-1 and 102-2, and one or more center supporting plates 106 holding the at least two rods 102-1 and 102-2 to form a rigid structure, wherein the at least two rods 102-1 and 102-2 are overlapped to form a crossed structure wherein ends of the at least two rods 102-1 and 102-2 construe a polygon, and wherein a plurality of propellers 204 are operatively coupled at the ends of the at least two rods to enable flight of the UAV. The frame structure includes at least four overlapping arms 104-1, 104-2, 104-3 and 104-2, at least two of which are present in different planes and thus, the present disclosure provides a non-planar frame structure of a multi-rotor UAV.

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 rotors108 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 arms110 are oriented parallel to central frame 104, and a storage position in which arms110 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 manoeuvring 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 relates to a system and method for executing safe-return of an Unmanned Aerial Vehicle (UAV) moving along a path having a plurality of communication waypoints in the event of a communication failure. In an aspect, the proposed method can include the steps of detecting, at the UAV, a communication failure; enabling the UAV to return to last healthy communication waypoint location; and based on status of the communication failure, enabling the UAV to return to its home location.
