I created an autonomous intelligent ag sprayer drone that identifies and sprays only the wild blackberries (weeds) in my prairie grass. It worked surprisingly well and could be copied for other applications. This video will show you how it's built.
Note - This is version 1 - it works but the system to identify weeds is a bit of a clooge. Version 2 is forthcoming and will use a raspberry pi zero 2 to do onboard image processing and will work much better - I recommend going that route, raspberry pi zero 2's should be back in stock in the summer of 2023.

That sounds like an excellent project, and I bet you can do it. I'd recommend using an on boards pc/camera like the raspberry pi zero ($15) so you're not transmitting video over wireless to your base station as I did here. You'll get far superior image quality that way.

Thanks for an amazing video, loved it! How many acres can this drone cover with one battery before swapping it out for a charged one? Also how big is your spray tank? Would it be able to handle a bigger spray tank?

@nathanbuildsdiy 9 ай бұрын

Yes - it'll certainly take a bigger spray tank, next revision of this I'm going to 3d print the tank to save weight and hold a bit more liquid. It holds around 8 oz currently, I want to push it to 16oz. Since it only sprays when it has to I can cover about .5 acres per flight with that (my weeds are fairly dense in places) and I can get about a 12 minute flight to cover that .5 acres. I want to make everything bigger in the next revision as well. I saw an ag drone in my neighbors field (he had hired a company) that was around 8 feet square! It had a huge battery pack, and was fully human operated, no automation, but they covered something like 60 acres in an afternoon. They could swap batteries every 20 minutes or so and had a bunch charging in their trailer at all times.

This is a great overview and project, I have been researching this topic a little bit and this is the exact inspiration I needed to begin working on a similar project. In terms of open source autonomous drone flight, would you recommend starting with ardupilot, I want to explore the idea of mini auto swarm drones that are loaded with lightweight recognition models on board. So a software that can control multiple drones would be ideal.

Interesting build! I wonder if some sort of a two pass, batch approach would be interesting? first pass does relatively high speed scan/ video of the field. Drone returns to base and the video is downloaded and processed, and then the drone heads out with a new battery and the herbicide and does a high-speed spray run using the just calculated target data. Of course this depends on the system having sufficient locational accuracy and repeatability. I assume that for the most part the limit is air time so if the drone can move faster more of the field is covered at once. Thanks for the video

@nathanbuildsdiy Жыл бұрын

Interesting idea - flying higher and faster would let you get an overview of the field. I also think a raspberry pi + camera would get a much better resolution picture to enable that. Then the trouble would be that rpi+camera doesn't talk to the mission planner on the base station so it wouldn't know where it actually is in the field when it gets a photo. Perhaps comparing time stamps between the systems coudl sync up. I actually came up with a different solution - I built a lander/automated battery swap station that takes the hassle out of flying new missions. I don't have to be around, the drone lands, swaps batteries, gets loaded with a new mission and takes off for that mission

@nathanbuildsdiy 10 ай бұрын

Very good question. I just saw a company out of Illinois that a few farmers in my area hired to spray their entire field (no machine learning to only spray weeds), so it's cost competitive with crop dusters. Their drone was 8ftx8ft and could carry 10 gallons. The battery was enormous and they had a whole bunch of them charging and after flight they would manually swap battery/refill the tank. It was very cool (though not automated, had a crew of people running it). I've also seen the DJI Agras drone (2 gallons) which is also around 6 feet on a side. So, long answer to say I haven't built a drone that can carry a gallon (yet), but I'm guessing it'd be 3 feet or so on a side. I'm not sure how big the motors would be, perhaps start by researching what other ag drones (not automated, not Machine learning ready) are put together to get an idea of the motors and batteries used, then you could take that info and add in the machine learning/weed recognition. Let me know how it goes!

Hi, Nathan. Veeeery impressive work to bring all that together! Congrats! I’m a long-time drone builder/pilot. I’m also an experienced (self-taught coder. What I’m trying to decide now is whether to use nodejs (very little experience, although I’m experienced with JavaScript/jQuery) or Python. Never used python. There are so many options/ approaches to take to build something like you’ve built, my head is starting to spin. What do you think is the optimal approach for your next build? Python? Nodejs? Raspberry Pi Zero? Mini PC? If you could provide some overview of options, I’d appreciate it very much. I see a lot of pros/cons concerning the choices, but not directly related to a project such as yours. During your next build, make a step-by-step course available and you’ll have many buy it! I would! One last thing, promise. 😊 I have a DJI Naza V2 that’s been sitting in a box for years brand new. Can that be used in place of the Orange cube that coats so much?

@nathanbuildsdiy Жыл бұрын

Good questions. - For flying drones (including your DJI) with ardupilot/Mission planner I think you have to add a flight controller (an autopilot). In my case I chose cube orange, but a pixhawk could be used too. There is a cheaper knockoff pixhawk to save some $ which I tried but the GPS I used (here3) doesn't ship with a compatible connector to that one. There are videos about how to modify/solder the wires on the GPS to work with that cheaper pixhawk though. NET: pixhawk/cube orange are needed for use with ardupilot/mission planner. More info see here; discuss.ardupilot.org/t/control-a-dji-drone-through-pixhawk-and-ardupilot/39386 - I love python and raspberry pi and I'm using it for my next build (a robot, not a drone). It's inexpensive and easy to learn BUT you don't get ardupilot/gps out of the box there. Just a "robot" sort of control but importantly python is great for crunching numbers and working with tensorflow (machine learning from google - I use it for image classification). I think it's possible to add ardupilot/gps though as I've read a few headlines about that sort of thing, and if you could get that working it'd save money. That said, nodejs is also a fine language though it doesn't work out of the box with the open source machine learning. Go with what you're comfortable with and if you hit a wall where it can't do what you want switch languages or platforms

Hi Ralf, totally understand. It took me a few days of hard learning during the winter when I had no other projects to get my head around it. The "official" best places to start are things like this: www.tensorflow.org/tutorials/images/classification -> this is a "get started" to actually classify images on a pre-trained model www.tensorflow.org/tutorials/images/transfer_learning -> this is training a new model from a pre-trained one, basically feeding in new images to train the model as I did here If you've got a raspberry pi with a camera module, you can jump right in very quickly with this: github.com/tensorflow/examples/blob/master/lite/examples/image_classification/raspberry_pi/README.md I'm actually playing with that last one now. That said, check out minute 30 onwards of this video for how I "distilled" down these tutorials into something usable. First I took a pre-trained image (mobilenet) and hand-sorted images into "weed" and "not weed" folders on my computer, then retrained that mobilenet model on my folders. Then I took the resulting model and actually put it to use on future flights - I snapped images as the drone was flying and used my laptop running that model to classify them. Hope this helps!

It's the here3+ GPS that's the important thing. That gets GPS RTK which is far more precise and what I needed to be more exact with the passes in the field and to get the landings on the pad. The cube orange had the proper GPS port and the here3+ GPS documentation showed it worked with it. I actually started with a pixhawk and when I realized the here3 didn't have the same GPS port I got nervous and switched. I'm pretty sure I could have cut the wires and soldered them to use the pixhawk port but I wasn't sure if I'd introduce to much R/C and make the here3 unusable.

@nathanbuildsdiy 9 ай бұрын

I'm sure you can build that. You'll save quite a bit of money over my build because you don't need the cube orange and expensive Here3+ GPS if you're not relying on full automation. I used these with success for FPV camera/video from the drone back to my laptop (I see the video feed from the drone on my laptop) - I grabbed this from the description in this video (kzfaq.info/get/bejne/fMyclcaQ3pitd4U.html) Version 1 Camera System - *NOTE I don't recommend buying version 1. Version 2 will be WAY better and cheaper. Just wait for raspberri pi to be back in stock* 1 Runcam swift 2 FPV Camera - $28 (usa.banggood.com/RunCam-Swift...) 1 eachine 5.8GHz Video Transmitter TX805S - $35 (usa.banggood.com/Eachine-TX80...) 1 eachine ROTG02 5.8GHz receiver w/ USB - $31 (www.banggood.com/Eachine-ROTG...) You could keep the sprayer design I used or change it so it can deploy grain/powder, probably just change the pump in my design for a small motor that can deploy grains/powder when you activate it. You'll still need some way to control the drone. You could probably get a much cheaper pixhawk (instead of the cube orange) and a cheaper GPS, and still use ardupilot. These often come bundled together, something like this: www.amazon.com/Controller-Wireless-Telemetry-Quadcopter-Multirotor/dp/B07NRMFTXL/ I started by using a kit like that. In the end I decided the 900mhz radio didn't have enough range and the GPS wasn't accurate enough for my needs, nor did it have lidar, so I ended at the design in the video instead which is more expensive, but these kits certainly work with the limitations listed. There's probably even cheaper FPV enabled drones from DJI that are fully human controlled - no laptop used at all, and you could just add the grain/power distribution system onto that and figure out a way to turn it on when you want to. I've not got any experience with that, but I bet it's the least expensive option of them all.

wil the drone work in the rain? and water issues?

@nathanbuildsdiy 2 ай бұрын

Best not to fly in the rain. In a future version I'd like to have a weather sensor and pull a roof over the setup in case of rain

Where is the wire to the pump coming from??

@nathanbuildsdiy 2 ай бұрын

An ESC. The raspberry pi turns on the ESC which actually provides the power to the pump. Should be in the wiring diagram.

Why dont we like blackberries?

@nathanbuildsdiy 2 ай бұрын

LOL, good question! The land is in CRP (conservation reserve program) and is supposed to be native grasses. The blackberries got flagged for removal at the last check in. They're quite tough... so I came up with this. But more broadly, drone + image classification to only spray where necessary is a big win for agriculture. Less chemicals used while maintaining yields = cheaper cleaner food.

Excellent work a great example of engineering and determination. i can see you've put a whole lot into this. thanks for sharing. Many years ago i imagined a fleet of purpose-built drones designed to speedup the recovery of habitats after environmental catastrophes. A drone lands, gracefully drills and plants seed in holes and can alternatively carpet bomb large areas efficiently with tree seed-balls/seed-bombs. It's equipped with similar technology: GPS coordinates guide it to target fields, where it autonomously maps the area, considering environmental factors like soil type, slope, and climate. Based on these data, it plans an optimal grid layout for planting and its base-station prepares seed ball magazines. kzfaq.info/get/bejne/mr2pl9iI2NXdaKM.html&ab_channel=catfishbones kzfaq.info/get/bejne/hdeJh91nkuCrk5s.html&ab_channel=BareMtnFarm A reforestation game-changer in areas that are difficult to access. By autonomously selecting suitable vegetation and preloading seed magazines tailored for each pass, it ensures that every planting mission is tailored to its unique environment. To restore and heal exploited, damaged, burned, or abandoned lands!
