When you click on the motor to view the item it takes you to a 42mm stepper motor. Should it be a 35mm Is this wrong on your site??

Osman, did you even watched the video? You need some inertia on the higher part of the robot to get it to work. Check this video on how to balance a stick on you finger: kzread.info/dash/bejne/np-TstmuZ9HMYbg.html

Joop Brokking no, i dont know english im using translste

Joop i still didn't see in the net anybody with such complete and accurate informations/instructions as you. I deeply appreciate your effort and above all your passion. Many should learn from you.

I also want to say the thorough information you provide is great! The bringup steps, checking for overcurrent, etc, are particularly good. These steps are important for any project but almost never discussed. Many folks that view this tutorial, even if they don't build the robot, will learn important concepts they can use on future projects.

this is one of the first videos I actually see good wire management on the project

Thank you Joop, never seen such a perfect tutorial. The language clear to understand, no music, and all details to download. I just ordered the material and will try to reproduce this Robot. I'm shure, I will learn a lot. I can't understand those who gave a thumb dawn. Kind regards Otto

Thank you for writing me this comment. I really appreciate it!

I had nothing to do with the project but the description and commentary is so nicely done, it's just perfect!!!

i havent seen the next ep2 and ep3 videos, but i must say that your code and how you express your intruction in this ep1 is very very clear to understand, thank you for that

Excellent design and a great video!

Your work is inspiring, accompanied by your descriptions!

Any time I see a video from you I know its going to be interesting as well as educational. I enjoy the simple, complete and interesting way you present your video info. (for anyone who does not understand the concepts/idea of a balance bot and how it works using an accel/gyro look back in Joop Brokking's videos for compete simple to understand videos, using his DIY arduino quadcopter as the platform)

Found this video from adafruit. You've got my subscription. Cant wait to check out the rest of your videos!

Bit late to the party. Just made this Robot and must say what a well laid out and explained tutorial. I used 3D printed versions of the wooden bits. Had a bit of a problem with electromagnetic interference but tidying up the wiring and a couple of ferrite cores on the motor wires solved it.

Thanks for the great tutorial! So concise, like a Swiss watch!

Thanks so much! I've been looking for such a tutorial for such a long time!

Excellent video yet again, thank you so much! ☺

Thank you for the inspiration, think I will build something like this for my April project!

This is great! Greetings from Germany!

A nice little project to play with,.. clearly explained ( unlike many ),.. with the potential pitfalls of what to look for,.. a definite thumbs up

Great stuff I enjoyed your projects. Appreciate your effort. Its world class engineering.

there is nothing better than knowledge explained such that anyone can enjoy it

2 seconds in, I already know this is going to be awesome! 👍 :)

i have to say thank you for your amazing work i built this robot and worked perfectly thanks

AMIGO VOCÊ ALÉM DE GÊNIO, É UM SHOW. VALEU POR COMPARTILHAR UM PROJETO COMO ESSE...PARABÉNS.

Very cool project. Thanks for sharing your work!

Very comprehensive , Thanks for teaching this subject , Nice presentation

Awesome! I'm working on exactly the same project! I'm using 12V steppers and an adafruit motorshield V2.3 to control them and an mpu6050. When I started the project I just chose stepper motors because I thought they looked cooler haha

Thanks for such nice and comprehensive tutorial Joop :)

Respect man, very nice project!

Very well done. Excellent craftsmanship . I love your videos. Keep making more!!!! I subscribed :)

Excellent !!! Thank You for sharing your Knowledge !!!

You are an awesomely inspirational person thank you for your videos

awesome project and thanks for the explanations and detailed info , data etc.

Very Pleasent Tutorial & Video. Thanks for making my day.

Great Man! Thanks for posting video and plans.

Nice little project. This has lots of scope to be able to learn and replay movements..

Very nice project you have here. Everything is explained very good . Good job ! Keep it up .

Excellent @joop Im going to design this balancing robot too in my lab.. In previous YMFC is working fine.. Keep on rocking.. Now im doing ARDUINO CNC.. Share that one soon..

After I spend more than a month to gather all the stuff and to combine, finally I could build this robot. Thanks for you very detail information. But there are some issue that I cannot upload when this arduino is in place... so I have to take out to upload every time.. Anyway I will figure out. And you are right "limit current for step motor" is very important, I saw heated and smoke from diode before I limited current. Thanks a lot!!!

Cool project! Thanks for sharing!

Thank u so much Mr Joob for this perfect and accurate explanation, best regards

Great Work, i am building this one, really nice. Thanks a lot

Cool build! Sharing on The Awesomer.

You are awesome! thanks for posting this!

Thanks for the video. I built a dual axis solar tracker, going to build this robot to learn the MPU9265 to aid in my tracking instead of LDRs (doesn't do very well in cloudy conditions)

Cool thing ;-) I like the sound of the stepper motors :-)

Great work! Thanks for sharing.

Oooh! I've been meaning to build something like this!

i love the sound it makes

Absolutely awesome video, so if I wanted to make one twenty times the size, would the code have to be altered or not?

Genius! Just simple, Genius!

Amazing work Joop.

Nice and clear demonstrationen and the same for to the documentation as to what one need and how til assemble, much better than most others.

I'm so happy I subscribed to you 🙂

very nice complete tut! Thank you.

Thank you for the great project! One question.. Can I use this platform to make autonomous robot with ultrasonic censor? Or it's impossible because of 4 milliseconds main loop limit? Thank you.

Really thanks for this project, I made this and works perfectly, really thanks for sharing, all of your projects are amazing, regards from Ecuador

Hi Skyreacher. Congratulations on getting your robot project working. I've been working on this project for about 4 months. I'm at the point where I've soldered the boards and I know that my DRV8825s work and are set to appropriate current for the motors. I'm able to drive the steppers via the 8825s on a separate arduino circuit, no problems. However I'm finding some strange things on the main circuit. On Joop's diagram, resistors R2 and R3 are connected. Does this not effectively short out the purple and black and gray wires on the diagram? I get about a short between the gray and purple connections for the 8825s(lower right two pins) even when the 8825s are not on the board.The low voltage (5V) side of the circuits seem fine, but the high voltage side just goes to full power and the motors are frozen when the power is on. Can you confirm that the -ve side of the battery feeds BOTH the ground pins on the 8825s AND the GND pin on the step-down transformer that gives me the 5V supply for the components and around the low voltage sides of the circuit boards?. I'm at the point where I'm thinking of starting again with the circuit soldering. Any insights you can offer are greatly appreciated. I'm really looking forward to completing this project as I'm on a robotics study group in my board of education in Ontario Canada, working to build our capacity in Arduino and robotics.

Hi Gordon! Search for "voltage divider" to understand what R2 and R3 are doing. This part of the circuit is completely OK, it does not create a short. The wire between R2 and R3 is connected to A0 on the Arduino - this is used for monitoring the battery. When the battery becomes weak, the robot will stop working without damaging the battery. Yes, ground is the same on the whole circuit. All the black and light grey lines on Joop's diagram are connected. It sounds like there's a problem with your lower right two pins of the stepper driver (where high power is feed to them). If you test your circuit, there should be no connection between them. Having a short there can be dangerous for your battery! I'd not connect the battery at all, as long as the problem is there. Check your board very carefully, there must be a soldering problem somewhere (a connection between the purple and the light grey/black lines).

Great video. I am going to build one.

Dude, can you tell me how you got to these levels of pid control?

Great project! First the robot didn't work, but now it works. I had to wire the left motor with the right motor driver and the right motor with the left driver, then the balance worked. But why I must do this?

very nice! thanks for sharing. have a happy and prosper life

Congratulation, a really perfect Tutorial. If every teacher would have your qualtity, the world would be much further. Also verry good, no stupid music in the background as often. So your words are verry clear to understand, also by non english mother tonge people. Thank you Otto

this is excellent work , how small can this be feasible do you think , based on currently available components ?

Excellent brother!!!!!! Perfect

Hi Joop! Thank you for your video. Why did you use 1/4 step mode instead of 1/16? Was it because of torque or to increase the time step?

Since you made all this code,it should be super easy to transform this project to a xy joystick controlled project. I think many will like this. Just remove the wireless, the accelerometer and the extra code. It will allow anyone to make a xy controlled project!

Nice projects. I want to ask you if I can use the accelerometer to read vibration in a ball bearing as I am working on a project mixed between mechanics and electronics...Thank you.

Cool bro. Responce is response but very cool robot!

Great video!! I was wondering how hard it would be to build an Arduino based 3 axis brushless gimbal?

Excellently explained... :-)

Great Video ..very well explained.....as always......Thanks !!! BTW....Stepper Motor`s are an excellent choose for this project because of ...no backlash....in ballancing mode...

There are more benefits to the steppers - accurate (matching) speeds, direct speed command. The DC motors are normally controlled by just duty cycle. This is not speed but rather power control. There is a dead zone at low duty cycle (no motion due to friction). As a result more stable ballancing position (I built first one with DC motors)

Hello Joop, This project is awesome. Very much descriptive. I would like to suggest you to make a video series on developing a micro quadcopter with serial transceiver(eg. HC-05) or nrf24l01+ with self made remote(transmitter) just like you made YMFC video series. There is no such proper tutorial in youtube. I hope you would appreciate my suggestion and help enthusiasts just like you and me.

Hi Joop, any idea why the stepper motors work when not touching the ground, but halt and make a whirring noise when they do touch the ground? Everything else works well.

Great video. Would Nema 17 motors be ok for this project? I have a few spares from 3D Printer build.

That is realy cool!! Thanks so much!!

Additional question. Does the wheel size affect the calculations? If so, could the spreadsheet help to derive the new factors? Thanks

Great. Why put the Gyro in stand position instead of flat ? For giving plus and minus values from y pitch accelerometer ?

Are there "performance loss with variable battery voltage" for brushless dc motors as well? or do brushless motors behave like stepper motors? Thank you for the awesome videos, it has always fueled my interest in control engineering.:D

Can I ask you what changes did you made to the LIPO battery? I have the same one and Im wondering how you configured it so that it suits the rest of the elektronics.

Hi Joop, I went through all your videos about YABR and they're great! I am building one balancing robot by my self, but the difference is that I used a stm32 blue pill board instead of the Arduino board. Now I am stuck on modifying the code to make it work properly on stm32. Could you tell me how to modify the code for a stm32 board? please.

yeah! this is awesome! I wanna build it

Hey, so the hardware check says everything is all excellent.. the nun-chuck is recognized and the gyro works.. but i cant control the bot with the remote.. any thoughts i am so close to finishing this project.. i would love to get it done soon

Hi Joop, before to start with building, I'm studing your code and video. I read the comment here. Why it is so important the exat position of the MPU-6050? Why it shouldn't work if I put MPU-6050 a little bit top or bottom, right, left? Thank you in advance. BR

nice project.👍👌 :)

Great project and great video - very open and easy to follow, thanks. How easy would you feel it is for a beginner to port this to MicroPython on a Pi Pico?

Keep up the good work.

Thank you very much for an interesting project. The build is finished apart from the Arduino UNO, WiFi and controller. So my question is; should the robot be able to balance without the WiFi units?? Mine will not balance and seems to have a very large angle between the steppers actuating. It seems that maybe the gyro are correcting the wrong way. I have checked and double checked the wiring and it is OK

Nice work ;-)

HI Joop...Thank's for all this information and this great videos.... Didn't you need the capacitors in paralell with the 12V supply of the A4988 ? And.. Do this project work usin Arduino Mega 2560 ? Thank's very much...

Very beautiful and good job

Hi Joop Many thanks for your video, just a quick question, can I use this software with the geared DC motor instead do step motor? Thanks

I made the code for the stepper motors only. If you want to use normal dc motors you have to modify the code yourself.

wow Nice tutorial.. have its all details..

excellent project!

How does the MPU-6050 gyro and accelerometer compare to the one in the Arduino 101? Could the 101 be used instead?

Hi, I built your robot and it works very well, thanks but I have a question: I saw that you are using an "2.4G Wireless Serial Transparent Transceiver Module for Arduino" ... where can I get some documentation on this small board? I would like to know hot it works. Thanks

You are the best!

Interesting and Fully explained project. THanx for your efforts Joop Brokking. I can see that the post is old, so now: How about now using a Nano instead of Pro Mini together with 2x A4988, 2x JDY 40 2.4G (NRF24L01) and Stepper Motors +MPU6050. This would reduce the costs to less than 50% of what was in those years. Also the JDY-40 2.4G will not require a second Arduino (Uno in your case) for the remote (use simple 4 buttons sw for FF, RV, TL, TR all wired straight to the board ). this will make a tiny hand held RC operating with a small lipo. Loved your patience in Explaining in all the 3 video clips....I listened to them all.
