- Finally, have wheels back on my mechanical gyroscope, it is very stable and drives forward. No steering mechanism yet but that will be next version. Homemade cd rotor gyro, servo counterweight controlled by Arduino, and a little dc motor to provide go power.

Could you make a video tutorial how can make it for us?
Thanks !
ジャイロ効果！素晴らしい！
i am woking on similar kin of project. I am making a two wheeled bike balaced by gyroscope as line tracer i did the line tracing coding part on arduino atmega 8 but i am having difficulties in gyrroscope part
how did u manage to stabalize bike??do i have to add extra microcontroller??
Nice projects, How did you created the flywheel/weight disc/spinner?
5 stacked dvds held on motor shaft with rc propeller adapter. Not the best way. Later versions were machined rotors out of aluminum. Here is my pdf book on my blog site on how to build these things: demej00.wordpress.com/2020/02/08/self-balancing-gyroscope-two-wheeler/
@@demej00 this is a lot of information, thank you
@@av03 You are welcome. Good luck.
what components u used to make the gyroscopic run...which is that sensor and how it works...nd how can I buy that sensors and components coz m really intrstd in making a gyrostabilised car...plz help me??
Please check the link in the description. That shows most details. Sensor is just a potentiometer.
Hey jimmy
I need some help? If i use a flywheel with its axis horizontal (as in case of a steering wheel) and use a Potentiometer to measure tilt which read by adruino uno which changes the direction of motor i.e clockwise and anticlockwise of the flywheel so as to balance the whole wheeled drive.
Do you think it'll work?
If there any chance of it working I'll do solid modelling and simulation using solidworks. I just need some help here with my idea.
Waiting for your reply.
Regards.
The only thing I am sure of is that you have to try it to see if it will work. Yes, a steering wheel would make for a massive flywheel for the gyroscope and if you can get it spinning fast enough and just as importantly smooth enough, it should generate a lot of torque. Now, do you make it top heavy so that it basically precesses and keeps itself in balance, or bottom heavy where you will have to do a lot more processing to get it to balance. I don't know. Top heavy is easier but it will still be unstable if you make a turn in one direction, more stable if you turn in the other direction and it will just fall over if you jar the gyroscope too hard. Bottom heavy is more stable but harder to do. And if you expect to put this on an actual two wheel model or vehicle then you really need two gyroscopes rotating in opposite directions. Lots of questions only you can really answer by doing. I am tired of working on gyroscopes because they are so fickle and because no one out there seems to want to share really detailed information about building them for self-balancing purposes. Good luck Vishal!
Jimmy Demello thanks brother!
I'm motivated to do this as my major project.
I'll try to see which model works best!
Thanks for reaching me out and helping.
Hope you'll see some work from me.
Till then gud luck with your projects.
Good wishes.
COOL!
Why a 2 side pivot on gyroscope vs a fixed gyroscope?
Hi. A fixed gyroscope will not self-balance. The gimbal is required to exert a force 90 degrees from the forward and back tilting of the gyroscope itself. Here is a fantastic booklet that explains everything very well: thebbb.net/free/theories-and-experiments-for-gyro-monorails.pdf

Downward thrust
What will happen to your prototype if external force is applied..
Hi. From the side it is pretty stable and it will resist movement. But going around right corner, it will often fall over - no cornering ability to speak of because my gyro is not powerful enough (need bigger or faster) and I havent any coding to compensate for turning. Will work on that in the future just for fun.
may i ask what is the huge clamp/clip doing on the gyro?? thanks
Hi Devan. Yeah, it looks hokey but it was the only thing I had handy to make the gyro a little bit more top heavy. That's the only way it will self balance - the gyro must be top heavy - in my case the balance point is about a centimeter above the gimbal axis.
yay thanks.... can i ask another question... as i want to do a final year project something similar to this... there was another video using dual gyro, and if they are using 2 gyro are they spinning in the opposite directions... thank you so much :D
Yeah, the two gyros are best because a single gyro self stabilized bike tends to turn in one direction well but often falls over turning the other direction. So the two gyros counteract each others tendency to fall over. May be some other benefits too, I have never build one.
ok thank you so much.... i might try them thank u so much for the info...u the best
Thanks Devan. Good luck with your project. I would be very interested if you kept me updated. I don't know how much you know about self balancing gyros but there is another way to do it, like the C-1 motorcycle - actively controlling the gimbal with a servo. I have never gotten that to work but then I need a good gyro to do it and I never had one. The way I have been doing it is just using the natural precession of the robot to keep if balanced by making it top heavy.
How did u do it
Go here for my blog site to get my free ebook with all the details on how to build one: demej00.wordpress.com/2020/02/08/self-balancing-gyroscope-two-wheeler/
how did u do that
make a vide on that man
Too late, I moved and threw everything away. Don't think I have the motivation to make it again. Just got lucky that it even worked as well it did as I have since made self balancing gyros from hard disk drives and they don't even work as well as the sloppy one made with cds.
Gyros are weird.. I would have expexted the swivel axis to be side to side rather than back to front..
+akumabito2008 90 degree rule I guess. I love gyros. Am trying to get a custom built gyro that is much larger than my homebuilt job here to do some more stuff.
They are very cool. I've never played around with gyros before. I just came across the Lit Motors C1 and a 1960s era gyro-car and wondered how they worked. What are your plans once you get the biger gyro?
Dang I just lost a big reply I just typed in. Have to do it again. I sent an email to Lit motors and they responded. Told me they are using over 30 sensors to control the gyros. Thats why I think they wont make it (I hope Im wrong) because the number of things that can go wrong with two large computer controlled gyros, especially when they bike is at speed, is huge. I plan to use my rotor to see if I can make it self balance with just top weight but no movable weight. THen I want to see if I can computer control the gimbal which I have failed to do with my homemade rotor.
How did they control the tilt on the old gyro monorails of the 1920s? Seems like they worked just fine as a concept without using any sort of automated gyro controls: en.wikipedia.org/wiki/Gyro_monorail
akumabito2008 The monorails used dual gyros just like the C-1. But they were huge. The C-1 spins their gyros fast and they need instant response. The gyrocar used one gyro but had problems with left hand turns - same as my version 5 gyro bike - it would fall over on sharp right turns. I saw one diagram that showed the gyrocar using a counterweight too just like my gyro bike. Probably where I got the idea. I think the C-1 needs really fast response like when you are jerking the bike around at speed and hence the need for computer control. Just guessin.
