Congratulations on your degree. I found your channel recently and I am really impressed.

If you want you could put some smaller, higher rpm motors on this guy for its cutting blades and just increase the weight of the disc. Just make sure you start it on a clean surface. Doing that should make sure you get all the grass in the one pass.

Would a Cylinder Lawn Mower work longer? (More power efficient)

oh hey i made a servo actuator set for the openroboticplatform it needs some kinks work on but i can wait to post it.

Can I come an meet you

Gratz! And very cool project here!

RTK would still be a really nice technology

Congratulations on completing your degree Nikodem!

You're awesome. Subscribed

did you go to open sauce?

I need something and help to test run my stepper motors.

They're low speed performance propellers. They're meant for sustained, low speed flight. Which isnt ideal for drones, especially because the original design is massive compared to a drone. And it's made massive because their performance decreases steeply as you miniaturise it.

If you use motor to turn both in the middle of the mower, you will have a line in the middle of pass...

Have you considered using trimmer line instead of blades for the cutters? Would definitely be lighter and probably safer. Easier to maintain too. No sharpening.

Hi Nikodem! Congratulations my friend for your degree! It's a personal great achievement. I'm happy to be among the very first subscribers who rapidly noticed you had energy, skills and the willing to gather the needed skills to build serious devices from A to Z, many YEARS ago. Your projects and your audience as well, will be part of the beneficiary of your complete knowledge. Pretty exciting.

Can’t say ChatGPT was wrong. Since it’s a voltage divider, all it needs is a ratio (in this case approx 1:4 ) which can be achieved by either 27k and 10k or 2.7k and 1k if it made sense.

Congrats on getting your diploma, Mr. ehm, Master Nikodem! I wish you all the best for the future and lots of new (crazy) ideas that come to your mind. 😎

Can you test under water pump jet with torodial impellor

Cool video

You actually aren't far off at all it's just more powerful components with the 8sleep. Really though as you mentioned this is not a product for those who don't have air conditioning already as it will heat up your room overall more because of well, efficiency losses and simple thermodynamics. But if you have $4,000 to spend to make your mattress cold you also probably have an air conditioner to make the room itself cold so the heat generated by the 8sleep is not a problem in that case.

ChatGPT can be extremely useful but you have to know how to use it. When it comes to these things it's good to keep in mind that it's a language model, not a calculator, it doesn't understand numbers at all and it never will. The only way ChatGPT knows how to do anything with numbers is if it starts generating code and executing that code (which is what they're doing now), but even that is not flawless and a small error can quickly add up.

Congrats to getting the MoDS. Good luck for the future.

Throw a PV panel on top of it, and it will keep Wall-E company.

Please stop this "watch until the end" stuff. I see it more and more and I despise it, if your video is good I'll watch it to the end regardless, this just makes me not continue an other intersting video

PCB was hard to create: Next time, use JLCPCB as a sponsor :)

was it 5y to complete your master? or both your bachelor and master?

I'm excited to see what you will build with your knowledge of AI and machine learning.

I found a dead husqvarna (motherboard is dead), planning to use it as the base for my own arduino driven auto mower. The hardware is very simple. Here are some things you may want to know about it (happy to make a short video about it if you want to see it in more details for taking ideas from it) 2 wheels in front one in the back. 2 line sensors, one in the front and one closer to the back and they are offset only by a few centimeters so I guess this allows for better tracking of the line when trying to go home. all 3 motors are brushless but with extra wires for sensing "things" (I assume they have feedback on how they are turning or are to make the esc cheaper by providing a feedback signal). to detect "crashing" and even detecting hills the whole body is surrounded by a "shell" that is hold "floating" by some rubber masts, when you move the shell a couple of magnets move with it and two hall sensors inside can then detect the machine hit something or someone is lifting/tilting it (pretty clever). What I found amazing is how well isolated the inside and outside are, this machine was living outdoors in the sun and rain but the inside was pristine.

Not dogging on this design, but I have a question in general for all these robot mowers... why not just use an 18/40v weed trimmer motor/mechanism for the actual 'mower' portion? Everyone has so many issues with razor blades and other odd designs, but a weed-whacker works great, and is basically maintenance-free for months. Self-adjusting mechanisms.

The problem, is people keep thinking that chatgpt is an Ai...its not... It's a large language model that predicts text... It isn't a "computer", it can't do math...

Thanks! Congratulations on the degree!!

Nice. Please Nikoden, make a tutorial about manufacturing PCBs with the CNC machine.

Years ago when I did electronics at school we made PCBs by drawing or printing the design onto the copper then we put the PCB in a acid bath, is that not something that is done anymore?

Split your test area and let 3/4 fallow lest it get exhausted.

What do you recommend for a beginner with 20 yrs C/C++ experience to learn ML? I want to show it 3D computer generated designs, and have it learn to identify a real object. Also, can I get away with not knowing Python but 20+ years in C/C++?

Interesting project. If you improve the blades and add a bag it would do the job. The soft seem to work well.

Congrats Master.

Congratulations for your degree and thank you for sharing your progress!

Congratulations to your MA.

Congratulations for your degree!! Keep up the good work

I am very encouraged by your progress. I want to one day build something similar, but in my case, I need it to use rtk and / or imaging and/or lidar instead of a guide wire. Hopefully, your project will eventually progress to that phase so that I can follow your steps. Perhaps by that time, some of the more advanced components required will also go down in price. One thing you might consider is using a power bank that is wireless for your mower's power source to facilitate your self recharging station. Buying a cheap mower and retrofitting it is not that cheap in many places. It might be cheaper to buy a commercial device fully done. So i like your approach better.

Great project, and the best part is its really useful. I was thinking about create some sort of that for the last year. ps. I need to write something for the yt algorithm

I used Arduino (r3), my perimeter wire is galvanized steel electric fence wire (cheap, no need for transmitter) and inductive proximity sensor on the mower. I tried 4 blades on my first one, (looked like a hammer head shark), redesigns ended up with just one 400mm disc. I use [2] 25w solar panels to charge a 3s5p li ion battery pack. (power draw for the mower total is 19 watts) Cutter motor is 775 brushed, at 3v-1a. Wheel gear motors are 30 rpm @ 12v. (VT-555-12V- 5000R) Hope this helps. Thanks for your videos!!!

Regarding the direction of rotation for the mower blades- should they oppose one another because if they go the same way they could try rotate the mower- it would depend on how heavy they are and how fast they spin. Also the direction they move in could pile the cut grass up or spread it out.

Dziwi mnie tylko fakt, że pierwszą rzeczą przy DIY autonomicznej kosiarce nie była osłona ostrzy.

Myślałem, że masz z 16 lat

yeah the current versions of gpt struggle with complex maths. its surprising that the mistake for you was a factor of 10 and not something completely different, as it tends to be.
