Part 30 of the ongoing development of the Arduino controlled robot lawnmower – now fitted with high torque motor and gearbox to drive a cutting disc made from a used angle-grinder disc and very dangerous razor blades! – Music courtesy of “Billy in the Lowground” – “Meet me by the river”.

Silly madness 🙂
How did this lawnmower work out? Does it cut well? Does it run regularly?
I am so afraid of neighbor children messing with the pretty robot!!! I don't know why most of these designs do not use plastic string like a Weed-eater, as a grass cutter. Also, incorporate some sort of code in the arduino so if a sudden lift from any side of more than a certain angle/second will shut down the cutter motor. Of course there will be contours of the ground that move one edge up as the mower does it's work, but I am talking about the children lifting these up quickly to look at it. Also, I am afraid a neighbor might steal it. Is there a way to incorporate some sort of WiFi "Tether" so if it leaves the reach of your WiFi SSID range, it shuts down and can only be reset by putting it back into your WiFi range and pressing a certain button combo or something? I think you all are doing great work! Much better than the one I was trying to make that used an "invisible fence" doggy wire around the perimeter to define the yard space. Keep it going guys! When you get it right, I will pay you for your plans!!!
Do you still have all your fingers
ACE!
God that is beautiful, fantastic work!
How much did it cost to make this? I'm at work so can't watch the video atm!
Good idea ,I like it

I purchased this mower as a gift for my son>>>t.co/4tnwTWryaw I can't rate its performance but my son seems to be happy with it.
I suggest you to change motor driver, that motor drive have ridiculously high drop down voltage
Efficiency is terrible
Awesome project!
Hi any chance on releasing the arduino code please 🙂
I like this model over the others i have watched
staying with the disc cutter principle..you could use an old 4.5" diamond blade with snap off box cutter blades attached, these will give you a longer cutting edge with very little more weight 🙂
Like like ?????????????????????????????????????????????????????????????????????????????????????????
Great improvement! Big smile on my face! I wonder whats next?
what do you find best on your blades, skandi, convex or straight grind?
