I present some lessons learned about using a gyroscope to balance a structure or vehicle by constructing a model to demonstrate free precession. I have been able to balance this demonstration model over 15 seconds now before the gyro runs down.
UPDATE: just occurred to me that I don't need the extra weight - as one side of the gyroscope is already heavier than the other so I just spin up the gyro then swivel the heaviest side to the top and it actually balances longer and smoother than if I add weights.
You can actually make a motor/rotor gyroscope balance itself on two legs without any gimbal control - just by making the rotor or motor the heavier side of the motor/rotor pair. By being top heavy in a vertical axis gyroscope or one side heavy in a horizontal axis gimbal, it will correct itself as it falls to one side or the other. Also I have calculated and measured the total gyroscope weight to torque produced by the gyroscope and found that it is a 26% ratio - in other words the total gyroscope weight needs to be 26% of the torque produced by the gyroscope (can be calculated at gyroscopes.org/maths) to be able to keep itself balanced on two legs.

Again a great creation.
Thanks Anupam. I missed notification of your comment for some reason,
Excellent video. Thank you for explaining and the demonstration!
Thank you so much!

I am gonna make Mono wheel vehicle with this concept
Thank you for the video. I want to build a self leveling 'table top', or base, on which two cameras will be placed and pointing in opposite directions. The model will then be placed onto my boat's longitudinal centerline with the cameras pointing to port and starboard respectively. The idea is for the table top, or base, to remain level when the boat rocks side-to-side. When floating down a river I will then maintain a horizontal filming perspective and not have one pointing upwards while the other would point downwards without this self-leveling mechanism
Pretty cool idea! Good luck with it!
The marine market use a gyroscope to stabilize the boats, to make it pleasant. Look at seakeeper. Nice video, thanks!
Good stuff
hi, thx for ur video. u said when u move the gyro (tilt back) the structure will lean to the right,
so if u want to stabilize when the structure leaning to the right is tilt back the gyro. my question is what happens if u tilt back the gyro when the structure is already in balance position, will it lean to the right. I need this info if I want to build 2 wheel vehicle, because as we know motorcycle need to lean right/left when it comes to corner.
Inadhi. Yes, if the vehicle is in balance and you move the gyroscope one way or the other it will force a sideways movement of the vehicle. Good luck with your project. See my two wheel gyro vehicle I build a few years ago.
13:29 All the gyro machines featured in this video show that weight is added on to the top.
To make the gyro top heavy without adding weight, drill a new horizontal axis at a lower position than the existing gyro axis. This will change its center of gravity, and it'll keep the overall weight down. _The difficult thing about this is - The two piece axis shafts would need to be longer, or you have to make your tube-frame extend closer to the gyro_ .
*P.S. I don't know if this axis change - nullifies the gyroscopic procession effect, because the axis is no longer centered through the spinning flywheel.*
Thanks for the idea. Actually, all I had to do was flip the gyro over and it was top heavy without a weight. Worked very well.
That was much easier.
Maybe if there is one more axis if movement, where the gyro can tilt the other way, when the frame starts to tilt to one side, it may fix this
If the gyro rolls in another axis from side to side, the resulting moment would only affect the pitch and the pitch of the vehicle cannot change since it has a foot in the front and a foot in the back.
Very nice...

It looks like the wobble starts small and gradually gets larger and larger. At the bottom of gyro try putting a stop so gyro can only move 1/4 or 3/8 inch in both direction. This should stop the increase in wobble, but will balance remain?
you mean need made brains computer arduino and PID controller have perfect this
angular moment doent change it direction unless or untill external torque is applied that why it is not falling
does the gyroscope have to be located centered between the tweo wheels ( incase of a bycicle) or can it be moved further towards the rear wheel and still balance ? .. please answer
Hi Max. Just my opinion but between is best while other locations will still work but if it is extremely toward one wheel or the other then there will be an adverse effect on how the bike turns. Doesnt have to be exactly centered though.
what about turning the gyro upside down before release instead off adding weight on top?
Discovered that previously - see my description.
Wouldn't it balance better if the weight was on the bottom? or maybe make the cross bar have a bow downwards to center the balance to te middle? I was hoping to see you demonstrate the bottom weighted..
I also noticed that your Gyro sounds like it has a lot of friction due to poor fittings, maybe create a ball bearing gyro with a big bar bell weight?
It won't balance if the center of gravity of the gyro is below the center of cross bar, the system will slowly fall aside, due to the precession.
Yes, it was a cheapy.
Sir we are currently working on gyroscopoly balanced two wheel bike as our project and we are facing some problems in balancing.
It would be very grateful for us if u help to solve our problem.
Booklet I just wrote on the subject: www.scribd.com/document/451958738/How-to-Build-a-Self-Balancing-Gyroscopic-Vehicle
5:58, can anyone explain this self correcting mechanism? I need more info on it. thx!
Gyroscopic procession is hard to grasp because it so strange.
This is gyroscope . Gyroscope has ability to fix itself to an angle and a place while it spin.
A very scientific gyroscope is used to stabilize a telescope in space like Hubble . Or airplane ✈️ to balance
Try building one, it becomes obvious when you do. Free ebook on how to build motorized two-wheeler here: demej00.wordpress.com/2020/02/08/self-balancing-gyroscope-two-wheeler/
1. If I build a car on but two wheels, will I be able to balance it with a Gyroscope? While riding it, I mean.
2. If I build a house on unstable ground, will I be able to balance it with a big enough Gyroscope?
In answer to #1 see Lit Motors C-1 motorcycle and there is a historical precedence for two wheel cars but they are not viable unless using two counter rotating gyroscopes.
In answer to #2 - anything is possible - a gyroscope can be scaled up. That would be interesting - even a model of a self balancing house.
So how does this tie into an MBT stabilizing its main cannon?
I guess it will help if the tank has only a single track.
I want to make an enicycle.For the purpose of balancing, I need gyroscope. Could you please help me for making this possible?
Awaiting your reply.
Sorry I have no experience building an enicycle.
How much should be the radius of gyroscopic disc with respect to the mass of the body? Is there any formula how we will judge the radius?
Go to this website: www.gyroscopes.org/math.asp
You can see that by increasing the radius, you can achieve the same force as if you doubled the mass by increasing the thickness of the rotor. So increasing the radius of the rotor is always most effective. But practicality enters in as you don't want a rotor with a diameter so large that it becomes cumbersome to use.
Also look at the math section in my ebook on how to build these things on my my blog site: demej00.wordpress.com/2020/02/08/self-balancing-gyroscope-two-wheeler/
@@demej00 normal have 2 gyro and mass handle about 500 pound about then can use motorbike or bicykle and battery who spin gyros 10 000 rpm one CW and one CWW
Magic
Yes, a kind of magic. Love gyroscopes.
Where did you get the gyroscope? I've been looking for that particular one.
Hi Ron. I am in China so bought it on taobao.com. Not sure you can get it in US.
Thanks, that helped.
Jimmy, get yourself a copy of H.Crabtree (1914) "Spinning Tops and Gyroscopic Motion" (free online as its out of copywrite).
i think if you could get it to spin at a constant speed (motor) you would eliminate a variable.
john doe can i get the link of it please?

Where did the model car come from?
I used a toy gyroscope and made the frame out of fishing pole sections.

lot better if add 2 gyro, ccw and cw run gyro on frame, test this

bottom heavy more better 😉
This will never be self balancing.
So what is it doing in the video if not self-balancing. What do you call it? I am interested.
@@demej00 the video shows that the wobbling gets bigger and bigger and eventually the apparatus lies on the table. It's not self balancing as it can't be. As a whole it's top heavy.
@@Kogacarlo You are right, it is not a perpetual motion machine. Of course when the rotor stops moving, it falls over. The next step is to motorize the rotor and it stays up - which I have built many such machines. Here is one: th-cam.com/video/NsBnBMIeXeo/w-d-xo.html
@@demej00 You say that as long as the wheel keeps turning it will stay up? You are probably right, meaning that I am wrong. I stand corrected
Crap
Yeah I built it out of crap. I got the idea from a science photo but could find no documentation so just built it and low and behold it works. It is a wonderful principle and I just love how a gyroscope can make something self balance. It is what what makes the GyroXcar possible and Brennan monorail and almost seems like magic. Have a great day!
Again a great creation.
Thanks Anupam.
