Automatic lawn mowers are very modern, and very useful, because they take a lot of work from you. Unfortunately, but they are also very expensive! With this download project you can build your own robotic lawn mower at a fraction of the cost that one would have to apply for a commercial one.
The 3d printed robotic lawn mower works on the same principle as its commercial counterparts, which can be bought for a lot of money at most hardware stores. It drives in the inner space of a “boundary wire fence” (BWF). If it comes close to this it stops, turns and then it goes on mowing your lawn continuously. The robotic lawn mower is well tested for a lawn size up to 500m². If your lawn is bigger you need a second battery or you should print a second robotic lawn mower.
In addition to a 3D printer and the needed filament (ABS and PLA) for printing the parts, only a few tools and resources are needed to build the chassis. These are mainly common hobbyist tools. You do not need a lathe or a milling machine. Every common 3d printer with a build volume of minimum 180mm x 180mm x 60mm (x,y,z) is suitable.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
