Hi I see that you are using an aero ESC. this may not be the best choice to drive the blade as they normally get more air cooling. Check current draw of the cutter under load. may need to add a heatsink to use a brushless ESC intended for an RC car.

Child ride on car motors are dirt cheap, 200 dolla is a waste

I don't know if somebody else mentioned before, but why do you drive the robot from the rear instead of driving from the front? I mean just the opposite direction, will be much easier to drive

You probably want a big gear reduction for the wheels. It doesn’t need to go so fast and it will be much easier to modulate the speed in the ranges you can actually mow at.

I started (but never really finished) a very similar project a few years ago. In order to avoid expensive motor drivers, I DIYed some crude H-bridges with relays. The controllability of such a driver isn't great: the motors can only run at 100% power forwards or 100% backwards, nothing in between. But because all the current passes through simple relay leads, such a setup can handle a lot of power easily. For the relatively slow, highly geared down motors, the crappy controllability wasn't really an issue.

Great video. You should put four motors on.

Damn you are soo cute bro hahaha. And yes i love 3d printing 😅

Toroidal algorithms are way better for building but they need to be way more stable than normal mechanical devices because they not only generate more general force in pneumatic and hydraulic conditions than normal turbines but also have issues displacing the force across every point of stress in the shape. Its a more complex shape, so it needs a stabler rotor

Only air needed

❤👍

what about sticking some blades on a roomba

Great project. I’d love to see your own version of an ai powered robot like the ones from Larry’s workbench, makingmadeeasy, and RobGPT.

Super project! Love your approach, although mayge, just maybe give yourself enough time to think/brainstorm a little more. My first reaction is the mowing bed: it should be able to cut taller & thicker grass. Many other machines do it successfully with the same principle as yours. This might come back to haunt the project later. Either way, I love this and look forward to your next video. Good job!

Here's a comment for you, I subscribed 5 seconds into the video. I know a quality content creator deserving of a follow when I see one.

Firstly, really enjoyed the video! Second thing: I think if i remove the cage on my fan (I don't have kids and unlike kids, my cat is intelligent), I might just be able to sleep with it on...

once you start looking at autonomy, have a look at RTKlib, you can really integrate RTK for cheap these days

Very cool project. Did something very similar some weeks ago (didn't do a video on it yet). I started with a defective mower from ebay (mainboard was dead) and converted it to remote control. While watching I'm printing a new blade disk. Looking forward to the next part :)

You mean the hidden secret, quantum fan which the gov is hiding from the ppl, which gives free ac cooling

TORODORODOIDAL 😅

cool, I was building a Rep-al mower, but feature creap at the time made me not finish it :D. in the end I backed a mamotion luba mower on kickstarter. Mine was using sabertooth controller with ardurover, and GPS / RTK, as perimeter wire drives me nuts, we have a husqvarna, and the amount of times it has just nicked the wire. than later it corrodes and trying to find it is nuts. if you want to go gps and ardupilot way, check out "Yuri's Homebrew & DIY" here on youtube.

Go with gps and lidar instead of perimeter wire

at some point these clickbait videos need to be listed as misinformation...

I like the toroidal low pitch sound

Zipline drones have a better propeller shape, which is almost a wishbone shape, it's quieter and maybe more efficient than toroidal.

To me the noise of the toroidal fan was more tolerable and "easier on the ears."

Fantástic!

Nice! Turned the fan into making more brown noise without any performance losses. That's not too bad.

Thats nice😅

Is there any chance you're looking for design/prototype help? Little bits, pieces, connectors, etc.. I've been looking to start the same project, but I'd rather colab if it's possible.

kurde myślałem że to filmik za graniczy

Ohey! I love making little robot designs like this that require rugged durability, and I have two big recommendations right off the bat for this based on my own experiences! When 3D printing discs that need to spin without exploding, using the concentric fill for layers is super useful! If you use the default zigzag, your prints have a specific weakness in one horizontal direction, similar to layer separation problems. It can be particularly noticed when 3D printing gears. The proper solution to this, of course, is to waterjet some aluminum or other metal so you don't have a crucial part like that 3D printed! Additionally, when dealing with high-speed rotation, a very quick and easy self-diagnostic method the robot can use to ensure it's not damaged or malfunctioning is an accelerometer! In the case of a sawblade (or the saw-adjacent rotary hinged blades on your grass cutter mechanism) it's quite standard to include an accelerometer near the center of rotation, on a stationary part of the robot. This way, the signal can be quickly checked to see if there's any unexpected wobble or vibration each time the device spins up to speed, ensuring there's not unexpected friction (things caught in the bearing or mechanism!) or wobble (blade missing, broken, etc!) Hope these tips help! I love the idea of open source designs like this and I think youtube is a great community platform that allows creators to spread brilliant ideas :)

At least you can now say that you worked and lived in a Vault, haha!

After you tackle this, id love to see a diy roomba!

I think you should try balancing the fans. You might be introducing noise in the 3d printed version by having an off center, center of mass. It will vibrate like a rumble motor in a controller.

I also working in same kind of project remote control rc car using Mobile phone Use 18650 battery + You can get cheap type c bms + charge controller And use it You will get good capacity for cheap price and less weight your old motors are powerful enough for running I see the problem is lead acid battery it's heavy that's why it struggling

does not work 😒

Well very interesting study, I simple view the Toroidal shake a lot the fan stand.

Would you mind printing me one? Ill pay to have everything made and shipped!

Так, вы мне скажите русскому человеку, какая в итоге то лучше была.

Great job Nikodem! Can't wait for next part about boundry wire, I am curious how you solved it. I also did try to make mover but more heavy duty one, with wiper motors as a main powertrain, but these were overmade with too much power consumption. I have ended with motors from window window lift motors. As a blade motor I used 12V DC motor from power drill. I stopped now because I have no idea which sensors to use to sense the boundry wire.

I prefer your version, even tho the sound intensity is the same, the sound is lower pitched, and for me the high pich of the origial one is really annoying

Nice work! I need one for my lawn

Battle Bot next video?

just build a battlebot, if it fails you still have a lawnmower.
