This 3D-printed, Arduino-powered robotic mower will take care of your lawn for you


Build your own Ardumower for less than $300.


Mowing the lawn; it’s a nice slice of solitude and exercise for some, and an arduous task for others, to be avoided at all costs. If you fall into that second category, then the Ardumower might be for you. According to its description,“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 mower itself is an interesting build, with a nicely sloped canopy and driving wheels that resemble something found inside of a clock. Housed inside is an Arduino Uno (ATmega328) and a motor driver board for control. Two 12V electrical motors are used for locomotion around a yard, while another motor turns the cutting blade.

The robo-mower is kept within your yard using a boundary wire fence to tell it when it has reached the limits of its domain. As seen in the video below, it also has some obstacle avoidance capability, though it would likely be best to keep it in an area free from animals, children, and irresponsible adults!

If you want to assemble one yourself, you can do so for about $250-$300 — a fraction of the cost of its commercial counterparts. A manual, which is available for $12.16, claims to give step-by-step directions to build your own Ardumower (or maybe two for larger lawns!), as well as info on how to create the boundary fence.
