Summer is rapidly approaching (at least for those of us living in the Northern Hemisphere) and if you are having to maintain a lawn at your home, now is the time to be thinking about irrigation. Plenty of people have built-in sprinkler systems to care for their turf, but this is little (if any) fun for any children that might like to play in those sprinklers. This sprinkler solves that problem, functioning as an automatic water gun turret for anyone passing by.
This project was less a specific sprinkler build and more of a way to reuse some Khadas VIM3 single-board computers that the project’s creator, [Neil], wanted to use for something other than mining crypto. The boards have a neural processing unit (NPU) in them which makes them ideal for computer vision projects like this. The camera input is fed into the NPU which then directs the turret to the correct position using yaw and pitch drivers. It’s built out of mostly aluminum extrusion and 3D printed parts, and the project’s page goes into great details about all of the parts needed if you are interested in replicating the build.
[Neil] is also actively working on improving the project, especially around the turret’s ability to identify and track objects using OpenCV. We certainly look forward to more versions of this build in the future, and in the meantime be sure to check out some other automated sprinkler builds we’ve seen which solve different problems.

That’s anything but grass.
Thats a garden full of green weed.
monoculture or it doesn’t count eh
It’s literally not grass. Whether it’s considered a weed or not is another matter, but it’s not grass.
Poaceae (grass) family or it doesn’t count, ya.
Now, please tell me how I’m killing the planet with my typical lawn.
When the terminator shoots you it doesn’t feel this fun.
I think this one, should appoint a visit for prostate exam.
Now I just need openCV to reliably identify dogs that even think about beginning to squat… and immediately lock on the nearest human.
Dogs? Lol. I’m going for deer !! Something simular, just to keep them away from my fruit trees !!
Funny! Just a bit of controlled pressure regulator needed there for targeting different distances. Nice!
Very nice project, it would be for cats for me!
How about aiming at burning debris and have this mounted on a roof. It would need some intelligence to compensate for a strong wind bending the water stream. That’s my CA vote.
