What is "more accessible"? Ali, Ebay.

However, there is probably something wrong with the connections.

@@ReMRC I have a custom pcb, I checked like 20x and all of the connections are connected how they should be, I seriously dont know anymore

@@ReMRC Are you using a PNP or NPN transistor?

@@randomdudeidfk Of course n-p-n. If you use PN2222. I use another one, but it doesn't matter.

@@randomdudeidfk same problem here, buzzer keeps beeping, how did you solved it?

Nothing special is needed. Arduino serial monitor or any other program that does the same.

@@ReMRC Thanks, that worked, but I don't know how to follow or what to send, only get this message: first you need to calibrate the balancing points... How can I balance the points?

@@ReMRC I tried that comma d but nothing happened, maybe I didn't do the process properly, tomorrow I will try again. Thanks and sorry for not noticing that part

@@ReMRC Thanks!, that works :)

Reverse? What you mean?

@@ReMRCfor example,when you want turn right,first steer to left to make bike roll right .after roll to designated algle center the steer wheel. this might increase the manuverbility

Code for this project is currently not available on github.

No, bus all difference you can see in this video.

@@ReMRC Sorry, my bad, I ment as in uploading and setting up the code.

@@KerneIBit Setting the balancing points is different.

@@ReMRC Alright, Thanks!

Yes. Or watch this ruclips.net/video/Nkm9PoihZOI/видео.html

@@ReMRC aha, the one video I had not seen :) tnx

How? ruclips.net/video/ZU0oTBRDgOE/видео.html

@ReMRC Oh, a custom part has to go on the shaft to interface with the wheel. Thanks, I hadn't noticed that part before.

@@hummerman85 Custom part? No...

@ReMRC I can not find the file for the black part you have on the motor shaft seen here. I have almost everything and can't wait to finish it. Thank you for putting this together. ruclips.net/video/ZU0oTBRDgOE/видео.html

@@hummerman85 This is part of motor. These motors are sold with this pulley.

Then there would be no need for EDF. And it would be something like this ruclips.net/video/-fPYXWaVcOw/видео.html

i found everything except for the motors, does anyone know where i could find some.

@@K1VQ_andRandomStuff aliexpress or ebay.

Nidec24H is an easy way because there is a controller inside. FOC + BLDC can also be used.

I use encoder. It works very poorly without it. Don't do that.

Yes... But try to implement it. This is a difficult task...

@@ReMRC I can imagine, it would probably take a bit of time to crack the formula, maybe ChatGPT can help, but lately for the type of code I’ve been trying to make it’s not been doing what I asked it to do… but yeah, have you heard of “single wing planes ✈️ “? They invented this idea where it’s only one wing that controls the steering, thing is to turn when the wing is at high speed the pilot had to manually calculate how to turn on the fly, so it’s a similar concept, you can turn good, but the geometry of it needs to be programmed

Maybe the encoders are connected badly? Red connections in the schematic.

@@ReMRC Ah yes I got the encoder pins for the motors on my pcb design crossed so I just swapped the pins in software and now it works. Amazing upgrade, so much more stable and the wheels sometimes almost stand still. Is there a reason not to implement standing on all three sides of the cube?

@@sander368 Look at sensor orientation. :) In the first cube I didn't intend to do balancing on the edges. But I did it, although it works badly, and primarily because of the position of the sensor.

24H404H160

@@ReMRC Thanks a lot

I don't calculate.

Encoders have poor resolution. But it helps a little. However, this complicates the algorithm and requires more changes…

@@ReMRC I am using hall sensors instead of encoders. Would the new code improve balancing in this case?

@@nickp7339 Hall sensors with these motors?

@@ReMRC i used Maxon EC flat motors with hall sensors

@@nickp7339 Maxon are very good motors. But very expensive. :) The balancing algorithm needs to know the rotation speed. It doesn't matter what method is used for this.

The balancing point is determined by calibration.

@@ReMRC so it only works if your structure is perfectly symmetrical isnt it ? If your point of balance is changes by an extra mass your motors will saturate?

@@dolevwasser8639 You mean something like this? ruclips.net/video/aWhKnBbdXs0/видео.html

@@ReMRC exactly!!! How ? How do you change your reference angle ?

No, sorry. Code explaining would be time-consuming and uninteresting to most viewers...

Aloha! Glad you liked it.

You can see both cubes with new software at the end of the video.

@@ReMRC why didn't you include LEDs in scematic and when do LEDs turn on?

@@hunakaka Because the LED connection is very simple. And schematic is completely unnecessary.

Where not available? Ebay, Aliexpress always help me.

@@ReMRC Do you have a current link on Aliexpress for the motor? It seems it does not come up (at least not the 24H404H160 version.

@@bi0530 24H404H160 shows exactly that version.

No, center of mass is important.

This is not easy. Why you can see here: ruclips.net/video/PwZfTrd_3Jg/видео.html

You mean like this? ruclips.net/video/PwZfTrd_3Jg/видео.html

@@ReMRC Yes! nice. That is doable in this current build? I'm just waiting on the motors to show up. I will make the new print in the meantime.

@@elidelia2653 No, it's hard to make good brakes that always work the same way. It also requires additional space.

Gyroscope precession - no. This is reaction wheel. It works by creating a torque through changing its momentum.

@ReMRC hi. I was reading a bit more yesterday. I believe it works just generating a torque in the wheel opposite to the torque of the weight, is it right?...

@@RGDot422 If you rotating the weight, you get the torque in opposite direction.

@@carjavitube Yes. Watch another video about cube.

ZH 1.5mm. But they come with motors.

You can make any two-wheeled balancing robot that can move fast (lots of projects online) and change the wheels to omni wheels. It will work similarly.

Why did you buy 12 pin motors? It's not the same.

Because there are no others, and I can’t find yours, I noticed only after they​@@ReMRC

You don't need to adjust the k1 k2 k3 k4 values if you try to build this project.

@@ReMRC I have adapted it for use with your triangle balancer

@@vietle-fr5rj I didn't understand what you wanted to say. Can it be more precise?

@@ReMRC sorry for the slow reply, i want to know how to adjust the k1 k2 k3 k4 values ​​in your code in this project to use for this ruclips.net/video/aWhKnBbdXs0/видео.html&t =4s

@@vietle-fr5rj I don't have any method. Only the experience of making quite a few balancing robots.

Empty. :) I don't use any libraries for this project.

@@ReMRC Hello thanks for reply, im building this project and im facing one small problem. Its that when i use 115200 baud its not working, and im now using 38400 and its kinda working but its angle values always being 0. If you have any suggestion or help please let me know, thanks.

@@hope-yn5sl ESP32? 115200 baud should work, it doesn't depend on my code. Also, you need to try any mpu6050 data read example.

I don't have a schematic. You need to understand that I don't need it.

First of all: does the motor test work normally? About the buzzer - apparently you are using a passive buzzer. Active is required.

​@@ReMRC thank you, Ok for buzzer, It's not really a problem now with "tone." but thank you for this detail (I didn't see "active" requirement, my bad). Yes the motor test is OK, turn one motor clockwise and counterclockwise slowly, 1, then 2, then 3 and loop. On one of three side the three motors turn, as it was on vertex but not. Never only one motor turns

@@esope60 Something is mixed up though. Two motors together never work... Also tone() function will interfere with PWM... I don't know how it can interfere with ESP32.

@@ReMRC So You are very talented... I cut the tone. command for the moment, and motors don't turn anymore after the boot... I mixed two motors and now only one motor turns on his own axe. Each motor command the good edge. I've done again calibration. But motors turns without catch the balance. Is it normal motor turns everytime I do the "c-" ? I do c+, wait on balance point; then "c-", motor turns until I do another "c+" or put the cube on a face. On your video you can turn on another edge without turning. My motors seems to be too slow to change direction and catch up balancing. thank you

@@esope60 Motors should only start close to the balancing point. If the cube falls, the motors turn off. Nothing gets in the way of balancing? Wires?

Are you talking about the reaction wheel? It's not a gyro. The slower it spins, the better.

@@ReMRC I see, Can it be two reaction wheels on opposite direction ?

@@josacra Yes, but it doesn't make any sense.

You must understand that it is difficult for me to give advice. I don't know how you did it. There can be many reasons why it doesn't work. If you were doing exactly the same as me with the same code, I might wonder what's wrong.

@@ReMRC yeah I understand, cant shoot blind. I guess I have to first do a Nidec motor version to get a stable version, to eliminate noise involved, and then do a Brushed motor version. Sad I can't get Nidec around where o live. Have to find equivalents if at all available.

@@cholan2100 Ebay.

@@ReMRC got any place/mail where i can share snapshots of angle/pwm/rpm graph to see if it makes sense?

@@cholan2100 Yes, the email is in channel "About".

I don't have any lesson. It is basically the same as a two wheel balancing robot. Just use the omni wheels to move in the other direction.

Yes, 10 ms. I didn't need any additional data about motor. Only pinout.
