Abstract

The invention provides for a vertical takeoff and landing capable aerial vehicle with multiple rotors that is designed to carry agricultural sensors and telemetry allowing for real time control of agricultural equipment in accord with sensor data. The ability to carry a suite of agricultural sensors combined with multiple rotors will allow the craft to operate quickly in hovering and longitudinal flight over rows of farm fields and other vegetation and use an NDVI imager and other sensors to take data readings and real time imagery which will allow farmers and other personnel to determine vegetation type, need for chemical applications, plant fertilization, irrigation requirements, and other vegetation features including types of vegetation present. This will allow for precision agricultural, vegetation, and crop management and for farmers it will increase the efficiency of precision agriculture operations.

Claims

1. A multi-rotor autonomous, semiautonomous and remotely piloted unmanned aerial vehicle capable of vertical takeoff and landing comprising:

a center section consisting of two plates with an internal clamping system which bind body plates creating a rigid structural sandwich where the internal clamping system also holds rotor supporting frame shafts which extend out from in-between the plates in order to hold multiple rotors.

3. An aerial vehicle of claim 1 wherein the multiple frame shafts then hold multiple rotors driven by independent electric motors placed at their tips.

4. An aerial vehicle of claim 1 wherein the multiple frame shafts also hold and support electrical conduits connecting to the center section which then convey operational current and control signals to the electric motors from a microcontroller and onboard self stabilizing and navigational aid guided flight control system, remote control, electronic motor controls and battery system mounted to the center section of the aerial vehicle.

6. An aerial vehicle of claim 1 wherein an NDVI camera is affixed to the central structure allowing the unmanned aerial vehicle to take NDVI photographs of crops in order to calculate nitrogen content, crop type, other crop features, and the need for the addition of fertilizer, and or agricultural chemicals to crops to allow for precision distribution of agricultural resources in order to reduce pollution from farm runoff, increase cost effectiveness of farming activities, and increase farm efficiency.

8. An aerial vehicle of claim 1 wherein a crop sensor suite is affixed to the central structure allowing the unmanned aerial vehicle to calculate nitrogen content, moisture content, and determine the need for the addition of fertilizer, agricultural chemicals, and or irrigation to crops to allow for precision distribution of agricultural resources in order to reduce pollution from farm runoff, increase cost effectiveness of farming activities, and increase farm efficiency. Crop sensor suite may consists of cameras both infrared and near infrared, chemical detectors, and other analysis equipment suitable for calculating crop type, pollution, moisture content, and other crop features relevant to agricultural analysis and control or monitoring of other vegetation.

10. A vertical takeoff and landing capable aerial vehicle of claim 1 wherein the multiple shafts make up 3, 4, 6, 8, 10, or more rotor arm assemblies.

12. An aerial vehicle of claim 1 wherein an onboard microprocessor and data storage device is carried onboard in order to record NDVI crop data and or crop sensor suite data for processing at completion of flight.

14. A vertical takeoff and landing aerial vehicle of claim 1 wherein onboard telemetry routes flight instrumentation and GPS location data via radio modem to a remotely located central control facility or personal computer with ground control software so that real time flight control and tracking can be accomplished at the central ground control station.

16. A vertical takeoff and landing aerial vehicle of claim 1 wherein onboard telemetry routes NDVI camera data and or crop sensor suite data via radio modem to a remotely located central control facility so that real time crop monitoring and condition data can be monitored, recorded for future analysis, and or applied to the immediate control of agricultural equipment or other machinery.

18. A vertical takeoff and landing aerial vehicle of claim 1 wherein the automated flight control system interfaces with global positioning system and compass guidance and gyro stabilizes the aerial vehicle for optimum stabilization of the aerial agricultural sensor platform affixed to the central area of the drone, allowing for autonomous, semiautonomous, and stabilized remote control flight with or without altitude hold over farm land or vegetation.

2. An aerial vehicle capable of vertical takeoff and landing comprised of a center section consisting of a central hub with an internal structure holding multiple frame shafts which extend out from the central hub and hold independent electric motor driven rotors at their tips.

5. An aerial vehicle of claim 2 wherein frame shafts contain electrical conduit which convey operational current and control inputs to the electric motors from autonomous, semiautonomous, and user controlled inputs from the center section vehicle control system utilizing fly by wire control and automated flight management along with gyro stabilization.

7. An aerial vehicle of claim 2 wherein an NDVI camera is affixed to the central structure allowing the unmanned aerial vehicle to take NDVI photographs of crops in order to calculate nitrogen content, crop type, other crop features, and the need for the addition of fertilizer, and or agricultural chemicals to crops to allow for precision distribution of agricultural resources in order to reduce pollution from farm runoff, increase cost effectiveness of farming activities, and increase farm efficiency.
