In this video I'll show how i made a powered gyroscope that can travel along a monorail or tightrope. I'll explain how angular momentum keeps the
gyro upright, even when gravity or other external forces try to knock it over.
The gyro uses an 8" diameter flywheel printed with PLA, with 21 1/2" steel bolts around the edge to dramatically increase the moment of inertia.
Some performance figures:
Motor KV: 620
Motor Voltage: ~15V
Motor Speed: ~9,000 RPM
Flywheel Speed: ~3,000 RPM
Flywheel moment of inertia: 0.0138 kg*m^2
Flywheel kinetic energy: 680 J
Flywheel angular momentum: 4.3 kg-m^2/sec
Drive motor speed: ~120 RPM
The drive motor has plenty of torque to climb a steep incline, but traction is a major limiting factor, so the best i could manage was 10-15 degrees on a tightrope. In the future, I'd like to build a rack & pinion rail for the gyro to travel on so that it can go up extremely steep inclines without a problem.

The motor i used is out of production, but pretty much any other brushless motor of a similar KV will work fine.

Totally underrated channel
Its not underrated ppl just dont watch this stuff
@@michaelStrikess22zpeople do tho
Agreed
Agreed its undermeowed! i wonder if he made free energy machines before!
If the whole contraption was a motor by itself i think i will float like a UFO!
Underrated = good. overrated= bad
As a mech eng student, I found the whole process fascinating, more please sir! Thank you for using metric units 😅
Just discovered your channel, really awesome projects man!
Definitely going to be binging your videos for the forseeable future :)
My favorite part was calculations before making. I am over 30 years in engineering but it is always a feeling like magic that whatever you calculate works exactly as pre-calculated. I like you stuff man! Keep doing your engineering magic!
I’m going to show this to my students. We are just covering rotational and circular motion. I’ve recently 3D printed a walking robot that uses a gyroscope (spinning columns of pennies) and uses the precession of the gyro to rotate and take its next step. I just need to find a few more screws to finish putting it together. This is an awesome project! Keep up the great work!
Just a thought, could you setup a gyro stable enough to measure the earth’s rotation? If you mount the gyro horizontally (the spin axis is parallel to the ground) and allow it to rotate perpendicular to its flywheel, it might pick up the earth’s rotation.
How would that make it measure earth’s rotation- and wouldn’t it be too small?
Not only can you, but that's where a gyroscope gets its name from! It allows you to observe (scope) the rotation (gyro) of the Earth (by maintaining the spatial orientation of its axis). Also for maximum effect, I would mount it with its axis perpendicular to Earth's axis. You should see it "change orientation" at 15 degrees per hour. You may need a high quality gyroscope though...
Now that you have something new to share with your students, I need to see your walking gyroscope to share it with my students! (I get the idea though, and might be able to come up with my own version of it.)
the earth doesn't rotate
@@throwawaypt2throwawaypt2-xp8nx you’d be correct if you ignore the evidence that says otherwise.
@@boomfiziks ok
9:10 and now turn the speed down again xD
I really enjoyed the explanations of the physics stuff, thanks for including them.
You can increase grip on the rope if the driving wheel has a V-shape profile instead of C shape.
The wobbling would be lead and lag of torque because of distance from the centre of the rotational mass would it not?I'm thinking there's lag building energy at the wheel point then it overcomes it at a point approaching lead or equilibrium then the wheel rolls forward and starts the cycle again. I'm not as smart as you but its just what I visualise in my mind
You could have added 2 aluminum disks for the bolts then it would have never flown apart...
Why your views and likes so low. Here take my Upvote. Great job man, expecting your next project.
Your channel is about to blow up, I'm calling it. Your content is excellent.
Still waiting.... but I agree with you, this is a criminally under-subscribed channel.
It will get there, great science Ed with mad scientist projects, just a matter of time
@@xntumrfo9ivrnwf getting there!
RUclips is not pushing quality content anymore. THey just want people to watch shorts
THey even stopped the scroll bar in desktops, so that people will click on 'Shorts'
this looks like tp secret military spy tech
hes probably one
How do you turn it off without touching it?
You don't, lol. I really need to make it remote controlled
let the battery drain of course 🐱👍🏿
I'm sure you know what you're doing, but with a device like this, one might have based it off a factory-made motor/flywheel combo, you know, something that doesn't need to be precision balanced because it already is.
It’s probably too late for this, but a brake disk would be a perfect flywheel.
too much weight in the hub....?
That did did NOT know what was going on!
But seriously that thing looks like it has sharp edges maybe put pool noodle type material on all the pointy bits next time so it can't scratch people/animals. Still very cool.
Also did you actually run that thing on hardwood floors?
Without active steering, gravity/center of gravity will still tip it over, eventually?
Wonderful projects on this channel! Love the detailed information. Thx
Would you be able to make this layout with the gyro, but use some type of rocket engine. Sort like a ufo concept. Just make a small engine to lift this gyro upward. But it may go off balance and crash into something
#4:51 Now I'm considering how one would go about making a solar powered kinetic energy bomb. For learning purposes only, of course.
Wow! Really good job! Continue with your amazing projects!
I'm actually amazed that your flywheel with that weight didn't break down at 3000 rpm that's insane
In retrospect, it was probably a very risky thing to do. In the future I think I'll just use a solid steel flywheel.
@@HyperspacePirate in retrospect.... hahaha. Brave doggie too. If you've answered this before I apologize but are you multidisciplined engineer?
@@HyperspacePirate I would at the very least have made a test part to see how much force can be put on the bolt before it breaks, to be able to set the rpm with some known safety factor
for flywheel, hollow sphere/donut w/water inside for centrifugal/centripetal spin.. option add magnetic compounds or polarized oxides in orb’ital fluid n spin gyro w/air pressure negating noise from drive motor e’mag fields..
@@HyperspacePirate Or drill through the heads and wire them together with some high-tensile cable.
Bonjour , pour évité que le gyroscope se mette à tourné, ne faudrait t il pas mettre un autre gyroscope au dessus qui tourne en sens inverse, ce qui aurai pour effet de supprimer le balancement, une meilleure stabilité , plus peut être la possibilité de lui faire changé de directions volontairement en accélérant un des gyroscope ou en le freinant légèrement ? À essayer non?
Excellent video and impressive concept as always 👍
I can tell from the vegetation you're a fellow Florida Man
i didnt see any alligators around
Woowww..
I've watched many clips of your Cilp. Maybe I think you're an alien. Is it with us people of the world? Hahaha 😂
You are amazing and multi-talented. much respect bro...
FC from Thailand
hes probably a retired NASA Nuclear scientist will a lot of free time on his palms 🐱👍🏿
Do you have a tutorial on how you did the CAD design?.....how many degrees of freedom does this Gyroscope have? I'm doing a similar project for my Project this year and would appreciate any help i can get!😁😁
If I timed the spinning bolts to release at the correct time, then it would work as a 45 cal gun? That doesn't seem right.
@5:31 - the rotational kinetic energy = 45 cal gun. What does it mean? Are you saying the total energy required to achieve the spin is the same energy as the bullet release, but spread over a much wider amount of time?
To clarify: the video says that it is important to calculate the limits of stress. Those limits were near the border of what the plastic can hold. Then the energy of the spinning disc is calculate to be a 45 cal bullet. This is dismissed and the project continues.
BUT where is the part in the video where it is explained how it is ok to produce an item that will throw 45 cal bolts in random directions if the plastic doesn't hold up?
Somewhere, the video should explain why it is ok to continue making something after the energy in the spinning bolts is like a bullet. How was it determined to be safe to continue?
Criminally underrated channel!
I bet FBI surveys this guys home for his "other" projects..
Forget hyperloop, this is what the future of transporation looks like🤣
Your contant are Awesome
This is really cool. I just love the physics behind this project.😊
you deserve front page recommendations. Not sure why your channel not as huge as the other tinkerers like Tom Stanton. Maybe make some plane vids :P
That very impressive. It almost looks like you know what you are doing! Ha ha ha. I love today's technology, 3d printin' n such! Thanks for a great video.
have you considered machining the wheel instead of 3d printing it? It'll withstand much higher stress
It’s a crime this thing doesn’t have some kind of shell to make it look like Claptrap.
Glad you explained the basic principles in terms only hard core engineers could understand. We wouldn't want ordinary plebes getting ahold of and using these secrets.
how the heck is omega a W?!
Love it. How about an upsized gyroscope backpack that provides enough assist to allow the average fit person to walk a tightrope.
The issue with that is that you'd need to make the whole body rigid, but still able to process, which isn't exactly conducive to beginner tightroping
Pretty Skookum. For some reason this guy reminds me of AvE and I dont know why.
Si quieres puedes anular el torque, poniendo un segundo volante de inercia girando en sentido contrario.
That would be cool and might be best, but I imagine is difficult to achieve, like high-tech rotors of advanced helicopters.
This thing needs a speaker that plays the tune from night rider. As I make my way thru your videos. Wanna guess witch video I watched first?
I've always thought that a gyro on the back of a puskbike or motorbike to keep it upright. This is the closest I've seen that is the same thinking with a workable model.👍
I'm curious about counter-rotating gyroscopes. Would they cancel each other's torque, so the whole thing wouldn't spin around? Would they also cancel each other's precession, causing them to no longer be useful?
They'd cancel each other out
@@HyperspacePirate in both regards?
I mean, such an arrangement would just fall over, if used in a device like shown in the video?
@@zippythinginvention Yes the thing would just fall over.
@@Panthlessbut this idea is very much useful in propeller engine aircrafts. The designers really want to cancel the torque created by propellers.
Love the content. But if you're going to do engineering stuff please don't abuse "exponentially" like that.
A lot of physics, lot of maths behind such a toy....Great video..btw.
Damn! Amazing work! High IQs for sure
What if you add some ribbed pattern on the wheel to sit o-rings of various diameters to give it more grip for stiffer rails?
This is wicked , as for your belt slippage. Add a belt tensioner?
May I suggest repositioning the battery across from the motor to give better balance , servo tester and esc are light, and battery and motor are heavier which would help eliminate the stationary wobble
hmm.. 640 joules is the energy a 45 caliber bullet? That's interesting. Google says a AA battery has on the order of 10000 joules. So since a 45 can definitely kill you, I'm gonna start telling people a AA battery can kill you several times over. Which I am sure is true.. I mean you could cut it open and eat it, that probably wouldn't be good. Or you could charge a capacitor with it and stop your heart.. probably? Which leads me to the meaningless question of what is the minimum amount of energy needed to kill someone? Obviously it's meaningless since someone could just die on their own with no energy expenditure necessary.. in fact it takes energy to keep you alive. Idk where I was going with this but that was an interesting little tidbit that led me down a rabbit hole of thoughts.
minimum amount of energy needed to kill someone? FBI entered the chat....
Well, just think about how dangerous a fully charged super capacitor with the equivalent amount of energy would be.
The problem is you would never be able to fully charge that capacitor with an AA because of the low voltage. So the AA has a lot of energy, but you can only get it out very slowly.
could be used in rescue operations...
So much smarts and then he lets his dog's face get centimetres from a fast spinning mass of metal.
I think he knows and is just evil
Utter sorcery! we should apply these magicery on motorcycles as well!
Fun fact: A gyro spinning at 2x has 4x the energy, a gyro that is 2x mass has 2x energy. Thank you r2.
Is that where R2D2 gets its name?
Where did you get that toy gyroscope with the flanged wheel?
North Korea probably
(Bad)
This kind of clarification is very helpful
that shit goes over my head, but cool machine!
Ive been enjoying the crap out of your videos
Increíble, felicidades. Dios nos bendiga
I'm now expecting a Gizmoduck (Ducktales) like mode of transport. A self balancing, motor-gyro uni-bike. That's were my mine went anyway..
Great build and video man!
Excellent work. May I suggest you try putting it on a bicycle chain so it doesn't lose grip on the slopes.
That looks like south Florida and that rope looks like dollar tree rope.
I just came across your channel. Instant subscribe!
This is a beautiful contraption! Cheers
Totally love the explanations in your videos, please keep making more
the motor goes brrrrrrrrr
Cette magnifique prouesse sur le radiant de la Gravité est formidable c'est génial ❤

hey! quit it eith the funny words magic man!
If you need weights for further experiments, you can get tungsten-carbide pieces from McMaster-Carr, such as balls and cylinders. The density of TC is 14.5 grams per cubic centimeter, compared to
I love that you included and explained the maths and physics behind it!
Is this FreeCAD you're using here?
Totally underrated channel
I wish I had your creativity
sure u can! join the north korean nuclear missile project as a volunteer for 2yrs
Great stuff. Well done. Try adding a layer of silicone or butyl to the drive wheel for more grip. Let it mostly dry then use it. It will smooth off the silicone. I've done the same for upper side of the heel area of sandals, let it mostly dry then wear them, and it's still pliable enough to conform to my heel. Set aside and let it finish hardening.
That's so random and badass
Really cool video, love the way how to do the calculations before designing something, many RUclipsrs should learn from you…
Wow!!! Awesome project! Congratulations 👏

Keep it up!
"after an hour or two of cad design"???.... Genius, it would take me at least a couple of days 😂. I love you guys, even with the most obligatory mental superiority all american catch phrases!! Respect for using metric units, one day i hope soon, we will be free of the banana units and at last we engeeneers will be truly one!
Awesome video, even if i am "taking the mick" a abit, like our english friends say😁
