Proplers

Can you share you machine print model name?

What printer is that?

This was a great help, thank you

Imagine a rod 1km long with a spiral thread, now spin it at 10000rpm...another stationary rod above it. Attach a pod to the stationary rod, use a worm drive on the threaded rod. Why not travel at 1000kph. Yes, hydraulic and pneumatic are options and so is a Tesla disk turbine.

I came across this video after having successfully made a project exactly like the one you mentioned 1st, with the potenciometer. However, I tried doing something using serial comm as the source of the target position, but anytime I connect the powered motor driver to the arduino, serial comm doesnt work. I'm left disconnecting the driver anytime I want to type a number in serial comm. All the grounds have a single common ground point, so it's not a grounding issue. A friend suggested it might be electrical noise from the m.driver interfering with the arduino, what dya think? Thanks

nice project niko, and remember, we should fail fast and fail often when inventing, so we get to the success faster :)

como fazer as rodas girar pra frente e pra tras ao mesmo tempo? mudaria de direção mais rapido.

Regular fan had louder high frequency noise, so it was more annoying

great project, but maybe you chose too high rpm motors, for a nice mower you need around 30rpm

MIT didnt invet those toroidal props, they were used in boats way before MIT did anything with them

No. Go away

have the pivot wheel be the trailing wheel so it iant driving into the ground

No one older than thirty years should have a robot mower. They need the exercise of a hand-pushed one.

I look forward to seeing your progress on making this autonomous. A good start might be running the code with it communicating to a base station while you tweak the inputs, then transitioning to something that follows the guide line to build out a map. Keep up the good work!

You need 2 front wheels

What value to be used for dc power supply

Nice. How about bigger driving tyres?

Toroidal the best! Plus it's quite a conversation starter for the guests1 good work!

Also take a look at Zipline drone propellers

@4:01 that is why I only print with white PLA, it's to write sharpies notes on my design!

Others have said this, but I'll add to it: put the twin drive wheels at the front, so you're dragging the swivel wheel. This is called a "tadpole" for motor-trikes and pedal trikes, and it is both much more stable and means you're not jamming that single wheel into the ground and having to push past it. Putting it at the rear will drag it *over* the bumps instead of pushing it *into* the bumps.

Hello Niko your projects are great 👍, can you help try build a fast coin color sorter? i want to try to build a coinsorter that sorts colored coins with same sized coins, with different colors maybe you can help?

Funny thing is,, there is a system just like that for sale on Amazon for $45. You built that?

for the efficiency, just look at the blades of the aircraft engines, right?, I think they spent more energy and money to have the best efficiency

You could get away with drill motors at this weight as a heads up. You can get them from pawn shops for like 5 bucks.

I think the problem is not the motors but rather that it has a single small wheel in front and that generates a lot of pressure on the ground.

Sounds like you might not have a start capacitor connected to the motors and so the current draw is way to high to get the robot to start moving.

Better than paimon cuz its rich

Wybijaj się Polski Bratku 💪

It’s called a pedestal fan. :3

Hey, great video I’m trying to build my own robot for my university’s final project and i just need to know can i connect the LIDAR to esp32 and send the data via wifi to computer and also control the wheels with the esp32?

PRO plurz 🤔

Dont bother with the perimeter wire and look up ROS2 and NAV2 :)

co jest? nie dość że Polak z dobrym kontentem to jeszcze o imiennik

Polska ❤😅!! Uhuu!!

Normal fan: ssshhhhhhhhhh Toroidal fan: fffffffffffffff

There’s no such thing as a cooling fan. Fans don’t cool, they just push air from one area to another.

Co kropelka sklei sklei

Very good tree! I might need more practice for next time 😂😂

Nice cnc. Although the X axis seems to look weak compared to the Y axis. Also the Z seems not so rigid. Best to replace the X beams with larger alu profiles and put them vertical for rigidity. I also never like to see a belt transmission. This is also not rigid and causes the z guide to vibrate when doing a lead in.

How many people saying it is lazy are hand washing their clothes instead of using a washing machine?

Your accent is so thick

why do it manually 2 hours a week when you can automate it in 50 hours a week :P

does the big roller wheel in the front not push the grass down so its harder to cut? thats why most have 4 wheels so the blades can reach better. You could also experiment with just a piece of plastic wire at high rpm, that is what used for handheld mowers and is ment for higher grass :)

the wobbling tells me you could improve it by balancing it with weights & maybe try an odd number of blades version.

Nicr

No difference. Even the annoyance level is the same.
