I bought the construction manual and read it before I start assembling. Seems that I understand it completely, so it's written incredibly well. Thank you for creating this. Are there kits available so that we need not purchase every component seperately?
I am making this now. My PLA filament cost $16 USD per 1Kg spool. I have built all of the larger parts except the electronics boxes and covers and so far have used about 2/3 of a 1Kg spool. Parts on my Anet A8/Prusia i3 printer haven taken several days to print. I have purchased 4 of the drive motors on ebay from china that are used. I only need 2 motors for one bot, but I plan on making four total. I have created a spreadsheet keeping track of all costs and costs for my time to make the printed parts (not the time for actual printing, only my time in setting it up on the printer) So far, my estimate is about $150-$250 US to make one robot. Depends on how many parts you already have. Also, purchasing the drill bits and taps to make the threads is a one-time purchase. So, if making four bots, I expect about $100 each. I will make two transmitters. One for the back yard and one for the front. I will put all four on the same yard at a time to make the process go quicker and I can keep an eye on them. Also, I have subscribed to the "learnelectronics" youtube channel. It shows very small projects with a very clear understanding of doing many arduino things, and a detailed analysis of the code involved and the wiring. I, too, am concerned about child safety. Spinning razors is not ideal in my book. I will make the cutting disc about 1/3 the diameter and add a way to put in the plastic wire you would use for a weed-eater to cut with. A smaller cutting disc should reduce the problem with the cutting motor being off-balance. Also, I am looking at impleenting arduino code that will monitor a gyro device in the loop part of the code, so if the device is lifted and the x or y axis changes beyond a certain amount, the cutting motor stops right away and the drive motors soon after. The only way to reset it will be to put a mangnet near a certain "secret" place where a hall-effect transistor is or a reed switch to make an Analog pin of the Arduino go low for at least 5 seconds. I really love the amount of work this guy has put into this project. I bought the plans for $10 and it is worth EVERY PENNY!!! Thank you Andreas Haeuser!
Just a thought. but how about making the top part a huge switch so that if there is any force exerted either by lifting or maybe if it ends up under staircase it would stop.
He provides options for using NiMh or LiPo batteries. You can buy the LiPo batteries from an RC done shop. They are 5C or 3S type batteries. Here is one option on Amazon. Make sure it is 5,000 mAh battery.
hi Andreas, i bought your drawings and i look forward to build your machine with both 3dprinting and cnc technologies. i have only one concern, it's about safety. i have a young boy and i'm sure he will try to lift the mower while cutting. i'd like yo know if you have ever considered a switch that stop the blades in case the mower is lifted up from any side. (i'm thinking of a switch somewhere on the motor mount.). thanks for your kind help.
@@fredbuecker849 No, those are not mower blades, a quick google search can easily show you what they are supposed to look like. They are either bent metal as a whole with the spinner or are akin to machining bits with hefty screw fixtures. Those look like M3 screws and if they aren't 3mm of high quality vibranium, they are going to fail very quickly. Want to do the shear force failure calculations when one of those blades hit a twig, pebble, or oxidizes even a little from the moisture in the grass? May as well mow the lawn yourself if you have to comb through the grass every time before these things set out so they don't accidentally seperate someone's ankle from their foot :/
thought of that, you could try putting smaller motors with cutters that would extrude a bit off the sides. either use regular cutting wire or you would have to design some retractable blade so it doesn't get damaged as quickly.
X-ACTO Knife lawn mower HELL YA.

Have fun with this project, John.

Can this be operated by remote control in addition to wire boundary?
That so cool I so wish I hade one of those I’d be playi with it everyday
What's the minimum size your 3D printer must be able to print? Is 100x100mm enough, or larger?
HI
It drives without remote?
Is there gps controller or what?
a few thin solar cells on top. maybe a cutter based on electric shaver designs. or targeted laser
cool!! what battery do you use and how long does it last

how much do all components (apart from the 3d printouts) cost?
a 1kg spool of PLA filament cost like $22. a rough estimate from looking at it, i probably can make 4-5 with the whole spool, so roughly $5?
for the 3d printed parts
+DrgRiderz17 my question was about all other components: motors, controllers....

Did you ever complete your mower project?
How long did it take you to print all the parts?
just abt 3 and a half years
on my ender 3 pro non stop printing with 80 per sent infill 7 and a half days lol
buongiorno x ricaricarsi come fa? sarei interessato al suo progetto
sir what is the rating of the cutting motor used here?
Buy the plans. $10 USD. It includes spec sheets for the motors.
Or pay $10 for a scam, those look like razor blades super glued to a spinning frizbee of death
@@Bajicoy They are actual electric mower blades and they get secured with screws. Just like on a commercial electric mower.

@@Bajicoy I have these plans. I am familiar with the parts. They are the same mower blades my coworker has on his $2k Husqvarna mower bot.
I tried to email you, but I got a bounce back, thoughts?

That grass...
Hai sir I am Isidro jr goc-ong.. I as you? what materials you make that robot. pls answer my sir. for my school project. I make like your lownmower..
Would be better if it has a cutter to do the edges like under the decks .
thought of that, you could try putting smaller motors with cutters that would extrude a bit off the sides. either use regular cutting wire or you would have to design some retractable blade so it doesn't get damaged as quickly.
pls help me sir.
