*Adjustable reaction wheels design is nice! Can get a range of torque that way.*

Great stuff as always.

I recently watched so many of your videos! Those are really cool! I am trying to make a simple reaction wheel my self but i have some problems with calibrating the PID. Can you tell me what library for MPU6050 are you using and what controlling algorithm? Is it PID, LQR or something else? Any tips on how to tune it?

I would like to try and make a little larger version of this reaction wheel to put in a backpack (for myself) as an experiment to attempt to balance/stabilize my Electric Unicycle in the lateral direction. Imagine how mind blowing that would be to the EUC world. You wouldn't have to put a foot down when you stop !!!! You could just sit or stand at a stop with no effort. I'm not looking to invent a new product for money because I'm REALLY retired and would never want to try to satisfy or jeopardize other people. I also realize that that Monowheels aren't really practical or needed but, I've always been fascinated one wheel vehicles and love the challenges of riding them electric self-balancing ones or manual.

Very good. I see that you are using different motors/controllers for this project. Do you like the gimbal motors better than the Nidec?

hello. I saw a video of making a 3-axis omni wheel ballbot. Seeing that, we thought that we would like to make a ballbot with wheels instead of omni wheels. We would like to make a 2-axis ballbot that uses two [Unicycle balancing robot with reaction wheel] and puts a ball in the center with the X and Y axes respectively. But I think balancing the ball with the wheel is two different things. I think additional tuning is needed to make the robot the way we want. I'm curious about what to consider when tuning like this, and through what process to fix it. In addition, I wonder if you think there is a possibility of making these ballbots.

I just want to see two of them stacked that’s all I want 😫

Hello. Great video. Maybe frequent question, but can I ask, what filament do you use?

this would be a sweet way to make a claptrap robot!

imagine this with full size mtb wheels....

any difference between these motors and the one from emax u used? cause the emax is like 8-9$ cheaper(and currently out of stock)

Hi. Very nice project I wanted to ask you how convenient it is to change the BLDC gimbal motors GBM2804H-100T to brushless motors, high efficiency 80T hollow shaft brushless motor (2204). What battery characteristics did you use?

as you listed "Gimbal controller BGC 3.1 with atmega328", can these 2 be replaced by 1 Arduino nano? or?

Thanks for the files, it's an excellent design. I have a question about the coding. Is it just a case of uploading the sketch you provided in arduino IDE? What's the "tuning" sketch for? Thanks Mark

I'm nearly at the point of giving up on this... It's all built and the sketch has been uploaded to my basecam bgc3.1 board. Not sure if my position sensors are connected to the right place but there was only one other set of headers for the rc receiver so that's where I connected them. When I power it up the motors take a few steps in each direction (one at a time) then that's it. What am I missing? Tried test mode and it's no different. Any calibration needed etc? What about arming/disarming? Thanks again!! Mark

Do you think I could do it using adx345 accelerometer ? I need to make something like this for a university projevt

Is there a procedure when powering on to get it to start? Calibrating or to arm it? Is Bluetooth needed or is that just for tuning. Thanks

I need some help with these as5600 sensors. How critical is the magnet position, distance and center? I've got a 3mm thick 6mm diameter disc magnet with opposite poles in top and bottom. When in test mode it works but it's jumpy and it will continue to spin in either direction. Also what values should I see in the serial monitor? Mine shows increasing numbers clockwise and decreasing anticlockwise. Right up into the hundreds and down to - hundreds. Any help would be much appreciated

HI! A very great project. Want to know if we can do the same with Simple FOC library but without the magnetic encoders. Please help me with this! thanks

Hi, I have build this project but use the BGC 3.1 Borstelloze Gimbal Controller/PTZ Controller w/6050 Sensor voor FPV Multirotor which is different then you use in this video. When I upload the code the motors turn a short time and then stops. Nothing happens next. Can this be a sensor problem or is this board different then you have used.

Could you please run me through how to set the balancing point in the code please. I've uncommented the print line then hold the model at its balancing point while looking at the x y values over Bluetooth. There to I put these values in the sketch. Thanks

It's great!!! Could you please give me the mathematical model you use to control the robot? And can you share with me 3D printed frame? Because I am doing a graduate project on the subject. But I don't really trust the mathematical model I found because I don't have the real model to compare!

If you ever want to add an English language voice to a video, let me know.

what is the battery?

How does ur robot turn

Can you show me the pictures of the components and sensors separately

Little bit of explanation of working and calculations would be helpful as well as overwhelming. Can any one kindly share explanation of such devices with mathematics?

Can you sell me one?
