UAV for agriculture applications

[Mechatronic]

Hi

I’m going to build UAV for agriculture applications and I want to know what equipment of your products do you recommend me?

My Quadcopter application will be for spraying and photography the land.
The most important key point is its weight. It must withstand the weight of 25 kg load.
And It should be able to spray 10,000 square meters about in 10-15 minutes.
What equipment with technical specification do you recommend for this case?

Best regards,
Reza

Hello @Mechatronic , that’s a pretty amazing project.

Well, there is a lot to take into account.

• Determine the prop size that your drone will run will be based on the frame size.

• Choose your stator size: A general rule of thumb is to classify your motors first by stator size and then lastly by KV after other factors have been considered. This page has suggestion values:

  
  .
  For a better motor selection you could check this motor calculator: https://www.ecalc.ch/ first and thus, looking the desire characteristic in robotshop brushless motor.
  Selecting the right motor comes down to weight, power, efficiency and torque and the importance of each of these are ultimately determined by your flying style and what you are trying to accomplish with your multi-rotor build. Ideally, you want to try to engineer your quad to efficiently fly, but also generate enough thrust without completely destroying your battery. You also want to build your quad for your flying style. A motor with a larger stator will also be heavier, and will have a slower response time due to the moment of inertia. So ideally, you should be able to choose a motor that is efficient, doesn’t draw too many amps, isn’t too heavy, and has the power to get the job done. For further suggestions, check this material.

• Size your ESCs: last, but not least, use the data that you find to make sure that you choose an ESC that can handle the current demand that your motor/prop combination will be requiring at WOT. Give yourself some room here- so if you are drawing 25A, choose a 30A esc, 18A, choose a 24A esc.

• For battery options: I’ll let you here a calculator to get an estimated value for your battery requirements. As one of your requirements is your fly time, you can also check this reference. Once you got an idea of your possible values and combinations, check the catalog for LiPo Batteries.

• Sensors: some options are, IMU, GPS, Barometer, Radiolink, ultrasonic.

• Microcontroller: Pixhawk microcontroller.

I hope this could help you !

@RoboCS
Thank you so much!
I will investigate it and discuss with you later
