So, Recently, I was asked to design a concept for an already existing project (Ardumower).
The goal of this project is to be able to print it in a 20x20x20 3D printer. of course, this would also cause design difficulties, but also many parts that would need fit be fitted together.
This project will be design after existing Hardware that one can buy from marotronics.
All parts have been printed in a smaller build size then 20x20x20.
Ardumower PCB Test:
The mower can be built either as a single mower or a double version. Your budget can decide. For questions about Hardware or code I refer to (Ardumower).
This is a great project if you want to build your on robot lawnmower.
If you like what I do, give me a shout at Twitter @

The parts, something like this
PCB 1.3 = with (Gyro, GPS, BL, DUE, INA, Motor driver, regnsensor, charger, Clock) = 226 euro
Motors 24V = 189 Euro
Battery = 140Euro
Mower motor = 70 Euro
Small update:
First rim for the robot is 3D printed. It came out great. The rim will be enclosed by a track with spikes 3D Printed with Flex-filament to reduce ground noise and also makes it easier to change tire pattern. Will also print a Centrum Cap with push- and screw fitting.

Wow! That’s a tremendous job! And what a beautiful result too!
The caster at the front seems somewhat tiny compared to the wheels. Do you know it gets stuck at all or maybe that’s not a problem?
Thanks @Arthurio.
Front caster will not be a problem. The drive motors are very strong and the COG is located just in front of the rear wheels, which makes it possible to even climb steep slopes
A very professional design. We have two main types of grass to consider for. Texas grass, the thick and deep vine St. Augustine and the straight blade thinner and shorter Bermuda style grass. This link will show the grass but also the landscape patterns.https://tlclandscapesllc.com/top-3-types-of-grass-for-texas/
The thick grass blade St. Augustine has a bumpy ride as a lawnmower may find deep nested pockets of grass where the root has barried. As well, the sidewalk usually has a gap and rise of about three inches.
For these types of lawns I would have designed the chassis with 6 wheels and flexible allies to conform better to the terrain. I would build this unit for the center of the lawn and a second with an all terrain chassis design.
Very nice looking with practical manufacturing considerations to upgrade as needed.
