Automatic water tarot keeps the grass watered

Summer is fast approaching (at least for those of us who live in the Northern Hemisphere) and if you need to maintain a lawn in your home, now is the time to think about irrigation. Many have built-in sprinkler systems to take care of their turf, but it’s a little (if any) fun for any kid who likes to play with these sprinklers. This sprinkler solves that problem, acting as an automatic water gun tower for anyone passing by.

The builder of the project, who had a specific sprinkler build low and a way to reuse some Khadas VIM3 single-board computers, [Neil], Mining wanted to use for something other than crypto The boards have a neural processing unit (NPU) that makes them ideal for such computer vision projects. The camera input is given to the NPU which then moves the tower to the correct position using Yao and the pitch driver. It is made up mostly of aluminum extrusion and 3D printed parts, and if you are interested in replicating the build, the project page goes into detail about all the necessary parts.

[Neil] Also actively working on project improvements, especially around Tarot’s ability to detect and track objects using OpenCV. We look forward to seeing more versions of this build in the future, and in the meantime be sure to check out some of the other automated sprinkler builds that we’ve addressed.
