  5. What's the minimum size your 3D printer must be able to print? Is 100x100mm enough, or larger?

  6. 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?

  8. 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!

  10. 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.

  12. 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..

  14. a few thin solar cells on top. maybe a cutter based on electric shaver designs. or targeted laser

  17. Hi Andreas, my name is Arvian Ordonez and I'm an intern for Discovery Channel Canada, for the show Daily Planet. I recently came across your video about the 3D printed lawn mower, and we would love to feature it in our show tonight. I was wondering if you would let us use the video. If so, is there an email you can provide for me to send you our disclaimer form for you to sign? I can be contacted at arvian.ordonez@bellmedia.ca Thanks for your time
