• Two axis reaction whee...
Cool.
Not what I expected, I thought you were going to stand it up on one vertex!
One vertex? Yes! ruclips.net/video/sT9be_IoEw8/видео.html
@@ReMRC awesome!
Ok, now on a vertex on a tennis ball! 😂
Joking aside, very, very impressive.
RUclips recommended me the video we are currently watching, but the one on one vertex is much more impressive! Nice work.
Ok, google recommended this to me also, and I was thinking on a piece of string, on the back of a motorcycle.. Is it just me??
@@ReMRC Amazing! Wow! ♥️
This is the same phenomenon for when you are tipping you put your hands and start waving them to balance
Yes, you understood correctly.
I need this in my shoes, when I go home from pub
To prevent you from tipping over? Then you need it on your hat, not shoes.
Love the part where it balances itself on a ping pong ball
Awesome! Great robot! Always enjoy your masterpiece! I imagined the hard and long time for tuning the controller. Inspired me to do more in this field.
“Tennis ball”
:) Better "ping pong ball"? "Table tennis, also known as ping-pong and whiff-whaff, is a sport in which two or four players hit a lightweight ball" (Wikipedia). We call it a tennis ball...
@@ReMRC tennis balls are the ones you use in tennis, the full sized one
Pedant! :)
Right? That's clearly a beer pong ball.
@@MichaelRainey I don't think beer pong is an official game, we call it a tennis ball as well...
I like the projects you do. Also this open cube design is awesome!
Very impressive, almost a Cubli!!
Excellent! Three axis wheels will let you balance it on a vertex. Hope you make it.
I've booked for future recommendation.
Nice
This video seems to be doing well with RUclips, because I have never seen any of your videos, and this was the first video on my front page :D
Keep it up mate 😉
I always enjoy watching your videos. Keep them coming!
What you call a tennis ball, I call a ping pong ball 🤣🤣🤣
staying on top and being stable are a bit different things, maybe one really fast rotation disc gyro, and two other perpendicular axes position altering wheel
one big fast spinning wheel on the top, passive stability, then active when wanting to change position
This is smart
Can you post a detailed guide on how you made it and programmed it !
What a cute little robot! :)
That’s some really good project right there!
Maybe an axel with flywheels on both sides?
This will increase overall weight, which is not good.
How was expecting a corner balance?
I couldn't see how amazing this was because the video was too quiet
There are many sudden toque on spinning to generate counter force in attempt to balance the system.
I am not sure whether it is more energy efficient than a wheel that run continuously spin under low torque.
Very impressive
Can you tell me how it's done please.....not Much details.... jargons will work
Thanks 😀
2:25 Would be even harder if bottom was flat. Also, ball is sitting on textured surface, making it more stable.
In the US that's a ping-pong ball :D
Great work. Awesome!
there is room to improve stability. but very nice balancing
Have you got the parts list and code ? I would love to build one
Awesome project. Is it necessary to have closed loop control? Why's the magnetometer feedback necessary?
BLDC motor in FOC mode (close loop) works very smoth...
Great project! Do you mind sharing the sourcecode?
Make cube with gyroscopes that rotating inside the cube on high speed.
Excellent. How did you pid regulate? What kind of filter did you use?
I use LQR. Tuned over bluetooth.
This can be used for leg amputees, right?
That's cool sir! Is it with PID?
LQR.
This is impressive! What gimbal motors and gimbal controller did you use?
BGC3.1, motors - GBM2804H-100T
@@ReMRC but why? Why didn't you use 2 nidec 24h as you did for balancing stick? Is there any limitations with those motors? Or you just tried different setup?
Thanks
@@AlexVKapa Of course with Nidec this would work too. I tried different setup.
@@ReMRC thank you for you reply!
that is such a good content and inspiring Robot thank you keep it up
So the difference in radius from the pivot point between the inner and outer rim of the wheels is what allows you to get a net impulse from a rotation?
Wheels size and weight. Inertia moment.
I saw you well. It's fun technique.
That was amazing! !gnizama saw tahT
정말 유튜브엔 없는 게 없구나
Endlich mal wieder was intelligentes! BG aus D.
But cosmetic change should be a test cube/companion cube from portal
Please teach how to do like this.
Great job!
Very very cool!
What feedback controller did you use? for example LQR, PID etc.
LQR.
AMAZING
What is the neccessary material you need for that?
Can you explain the equations you used for this??
Nice!
really awesome
Can you place it on one corner?
No, but this can ruclips.net/video/sT9be_IoEw8/видео.html
To me this is strongly genius
With a third motor it can fly 😁
This is my new favourite pointless device.
Impressive!
ΕΞΥΠΝΟ. ΜΕ ΔΥΟ ΥΔΡΑΡΓΙΡΙΚΟΥΣ ΔΙΑΚΟΠΤΕΣ
How about moving the batteries to the center of the machine? Your torque will be more effective if you do.
The center of gravity needs to be in the middle. The wheels are heavy, and weight in one direction. The battery slightly offsets...
@@ReMRC Ah. Yeah. Of course.
Very nice video and thank you very much !
If you do not mind me and my team are doing a similar project and we want to know the wheel 3D drawings and its dimensions if you do not mind
All the best
Thats awesome
Definitely need good tunnig for that tennis ball (ping pong ball)
I feel like if we wrote down the number of movements it makes it would tell us something
I am impressed :D
Is this SimpleFOC powered too?
Yes.
Build two more and stack them up on each other
did you try decreasing the circumfrence of the weighted wheels, should reduce stress on the motors
It would also reduce the arm the reaction force acts on, thus it would need higher accelleration to counteract the falling, which would eventually require the same amount of power.
Of course I tried... Bolts and nuts for this purpose. I can easily change the weight of the wheels.
@@ReMRC I ment like keep the w8 the same and decrease the circumfrence of the wheel. what do i know
@@gmunay420 Yes, I tried smaller wheels. Bigger is better...
Also I did many experiments with reaction wheels. You can see other my videos.
@@ReMRC TBH i havnt seen any of your other videos, think its cool what your doing.
Cool😄
Is this education kit? Possible to purchase it somewhere?
No. This is DIY.
Need faster motors and heavier wheels. Heaver wheels = more inertia = more potential resistance to force
and higher weight of the whole structure. Not that simple...
Start stacking them...
Wow!
Wai how cool
Do you offer designs? I'd like to make one.. teach me master!
where do you learn stuff like this?
I learn with make many experiments. Begin from this ruclips.net/video/wFZl9MwwkB8/видео.html
where did you source the esc´s from? i see they are symmetric in movement
Hmmm... This is a gimbal controller, but of course the program has been rewritten
@@ReMRC But the code is written on an arduino right? or have you embedded the code into the driver?
@@sharpnesstherapy502 This gimbal controller has atmega328 and several mosfets for drive bldc motor. Yes, it can be called an Arduino and can be write sketch with Arduino IDE. "Arduino" is just a name and nothing more.
thought you'd balance it on a corner
ruclips.net/video/sT9be_IoEw8/видео.html
Tennisbal? Really looks like a pingpong ball
I see your cat:)
How come you leave two empty screwholes on the wheels? Intentionally asymmetrical?
Asymmetrical? No. On the one hand, the construction needs to be as light as possible. On the other hand, a heavier wheel is needed. I put bolts and nuts for change weight...
@@ReMRC Ok! Do those empty holes make the wheel asymmetrical?
@@johnaweiss No.
@@johnaweiss If you split a rotating shape in half diagonally (with the pivot point on the line), and you find out that both sides have the same mass for every possible splitting orientation then the center of mass is on the choosen pivot point, so it is balanced.
What if you put wheel on each side then made them all spin at the same time very fast, then try moving it.
You talk about gyroscopic effect? This is reaction wheels.
@@ReMRC yea like a gyroscope but make it spin on the x and y axis or more. I'm curious to see if it's weightless or close to it from a video I seen a while ago where a guy spins a heavy weight with a drill and is able to lift it .
@@lucarini238 This is called gyroscopic precession.
@@ReMRC I know. I've been trying to find a way to spin 2 opposing wheels or a wheel on all sides of a box very fast and figured these could do what I was curious about seeing.
Show how cochlea work.
Segways use this tech?
No. If I understood the question correctly...
А если его поставить на угол?
Для этого нужен другой ruclips.net/video/sT9be_IoEw8/видео.html
👍👍👍👍👍
It can't balance on the vertex of cube? You shouldn't share this while not.
No, but you can see this ruclips.net/video/sT9be_IoEw8/видео.html
Beautiful, is it for sale?
wow!!!
try two motor on each side?
Better change motors.
ruclips.net/video/vXHlW2S24GQ/видео.html
👌👏
Great
noice
It looks like a child TIE fighter
You forgot to balance it on a corner...
Not forgot. :) ruclips.net/video/sT9be_IoEw8/видео.html
You seem disappointed with what you built even if it works pretty well
If you re not happy with it, feel free to send it to me
but can he beat goku?
❤🔥👍
can you do a proper tutorial on how to build this from scratch? u will surely get tones of views and help students at the same time.
I do not have time to describe in detail... Sorry.
@@ReMRC bruh how busy are u, just play rec and tell us lol

Ping pong ball. Not tennis.
I mean table tennis. :) Yes, I understand - ping pong.
@@ReMRC The tennis field, court, whatever, is many meters long and wide. So you didn' t get this correct, either. But at least the whole construction you made, was very good. So, there isn' t any serious problem. After all, my brain freezes also some times, as well.
Couldn't afford audio? At least a dictionary?
