I don't understand how you are able to release this kind of content so often. I can only imagine it would take me months to do just one of your projects. Awesome video as always!
Your work is straight up addictive to anyone with an interest in physics, robotics, and coding. I'm legitimately thinking about reading up on PID controllers, because imagining the FIR/IIR (I think these are appropriate) diagram of literally rerouting the output of the gyros to the set point is just satisfying, regardless of the hackyness. I remember having a terrible time trying to develop a balancing robot with my childhood NXT, and this would have been just the encouragement for me to go more advanced.
If you know maths up to derivatives and integrals, the PID controllers aren't that complicated. I play Factorio, and hacked a PID controller out of combinators to manage my laser turret power...
ball bearings for weight, interesting. spin that puppy fast enough and you got a claymore. also, if you put a picture of an eye on that gyro, its slow back and forth oscillation would look like an eye looking around the room.
So in order to get the gyroscopes up to speed I've installed several dozen ball bearings in these plastic discs and I'm going to spin them at several thousand rpm to initiate a grenade boosted backhop off of this ramp here-
thanks for visualizing control-systems in an easy to understand ways. Helps a lot to see physical applications instead of the lifeless block diagrams they hand you at university.
This was amazing! I was astounded to learn about the wave dampening gyros on boats you mentioned in Part 1, and this is even cooler to really see an application of gyro balancing. Great content!
Finally a use for a hubless bike wheel, That's where you put your gyroscopic flywheels. Regenerative braking is an efficient because the electricity has nowhere to go, the batteries can only take so much. You only need the gyroscopes going when the bike is stopped. Dump your regenerative braking into the gyroscopes. That also means you can get a boost from a dead stop without hammering your batteries. Store a little in the flywheels at all times, and you could have a boost button. The right computer logic you might even be able to get it to do some crazy cornering.
Some of his earlier videos are more like that. I got into learning it through watching them. I recommend any of Brad's "how would I build that" tutorials on the official site. He is a brilliant teacher.
Jesus christ that fanhome thing. "Only 99 cents for the first stage and 5 bucks for the next 3 stages, 9.99 per stage afterwards" Ok cool how many stages are there "100" Alright cool so this whole thing is only £975 in total instead of £999. thanks for the 2.5% discount guys, you're completely insane.
And you have to wait almost two years until you have all the parts to complete the model. I can see that most people are unable to spend 1000 bucks on a model, no matter how detailed and well made it is and that spreading that out to 100 payments will make it affordable. I for myself would never subscribe to such a thing. The waiting time would kill my motiviation and I would always fear that the company might go out of business before I have gotten all the parts.
Yeah, it's a classic sham. These things were popular in 1980s and even before then, they just brought it back. The end product is never as good as advertised as they don't have to worry about quality - most people will never get to the last stage as they get tired waiting and realize how much money they were drained of, and those who do last already spent their money so there's no point for them to regret their investment as it won't change anything.
@@tripwire76 I once had a subscription like this from a different company. I got half-way through the build and then received a faulty part. Got a replacement, which was faulty as well. Sent that one back again and then they were out of stock.
@@tripwire76 I mean yeah it's basically a scam. They're trying to get people hooked on the subscription because the longer you have been subscribed the more you "lose" on not completing the thing all the way. The only real expensive they have is tooling cost (all the injection molds, pretty pricy) and the licensing fees. They are offloading one of the most expensive steps in something like this, the assembly, to the customer. I'd bet the first 50 stages you receive are pure injection molded landfill junk. Actually, thinking about it, the entire thing is landfill junk. Pretty disappointed that James is promoting deceptive stuff like this, the website is deliberately vague on the amount of stages and total cost, and people do fall for stuff like this.
I'm not sure I understand how you did it, but I'm happy that your solution (have the bot oscillate around true balance) was the solution I had in mind. The (approximate) way to implement it I was thinking of was "if you're constantly having to move one direction, just overdo it for a bit, then go back to normal".
I always watch you James and immediately think, "why"? No offense, it is just my brain not being able to accept that these things need to be made. Yet, I quickly click on the video(s), sit back and just go WOW! You really address challenges that I will bet .001% of the hobbyists in this world will ever think of. Thank you for that! The simplicity in how you describe these what I perceive "way over the top" projects makes me feel like I too could make this balancing gyroscopic feat! Alas, I am humbled by the fact I can't code and Arduino are still something I need to dive in to. If I had the backend knowledge of the programming these projects wouldn't seem so daunting. Cheers to you!
Omg James you touched so many important Control Systems topics with this robot!!! This is really amazing!!! I wanted to suggest the 1 wheel Balancing Robot, that would be out of this world! Looking forward to do a pull on your git repository for this!!!
James Bruton, you should become the next Bruce Yeany. You already have almost all the projects. I had the idea from your introduction/summary of past projects in this series. You can make physics labs that incorporate real world physics into computer programming. Making these hands on, easy to see whats happening labs will be a good way to systematically revamp STEM (more input from more artful people than myself would be needed to turn it into STEAM). Think about this, I don't know if you wanna create a whole curriculum, but at least a standardized set of instructions with key learning points, fun build projects, and lab experience training would be really appreciated. From my lab experience in high school and college, they can and have helped. But in mechanical engineering, the most programming we do in lab is excel, which isn't much fun. (there's MATLAB but thats not till way later). I think you have a great opportunity to incorporate computer science with physics classes. Great videos, this is truly good content!!
Only Louis Brennan did it full scale 120 years ago but without 3D printers or Arduino computers to stabilise it and carried 40 people at a time on his gyro stabilised 22-ton prototype.
What you aren't including in your control scheme is the movement profile of the gyro motors. Speeding up and slowing down those motors in combination with managing the gyroscopic procession should let you move forward and backwards. Slightly angling the wheel mounts would let side tilt cause a turning radius. It would be interesting to see how much stable control you could manage. I remember following along with an online class called "Underactuated Robotics", and this machine makes me think of that
Moving the battery to the top will make this more stable if anyone is trying to do their own version with smaller gyros and less powerful motors. This one is obviously very cool the way it is.
Really cool. One minor mistake I noticed is that you put the battery at the bottom to lower the center of gravity. Having a low center of gravity is only helpful for something statically balanced.
If you have a single gyro in the center that can rotate 360 you wouldn't have to worry about it reaching the endstop. A one wheel balancing robot, Claptrap from borderlands would be awesome to make.
I'd like to see you build this robot with one driven wheel and a steering wheel, you could then make it effectively a remote control bike but that stays upright when stationary. Cool project. 👍👏👏👏👏
It would be very cool to build a miniaturized version of this into the head of a fancy cane, so that when activated the cane would stand up where you left it, balancing. I don't know what practical purpose it would serve, but it would be a neat "magic" trick!
It doesn't have to serve a practical purpose, but an undroppable cane would actually be really useful for the elderly. You can let go of the thing without it clattering to the floor immediately as long as it's close to upright, I can see that being worth a couple hundred bucks.
@@Teth47 Actually if twisting a spinning gyro around an axis perpendicular to the spin axis gives you a force perpendicular to the plane described by the spinning and twisting axes, with a slipring to power the gyro's primary spinning axis, you could make it so that the twisting axis could twist continuously, which, with a sufficiently heavy gyro weight and/or high enough spinning speed, would allow the cane to stand up from even completely upside down. Whether or not you could fit that into a cane, idk :P
Am i the only one worried that the 3d printed flywheel turns into a shrapnel lauchner? be carefull james.. long life fatigue strength of 3d printed parts is really bad. with a wobbly design this means every rotation of this 3d is a countdown to a dangerous failure of your machine. you could replace the steel balls with sand or something more harmless.
For projects like these, you'd probably save money and get better results if you bought a bunch of lead shot, filled a void in the print then put enough in that when you close the print, the clamping force holds everything together (like mechanically stabilized dirt if you've seen that video).
If you built it so that gyro wheels could rotate continuously (such as using a slipring to get power to the gyros) you could even allow it to hold position at 45° angles indefinitely.
Hmm, How about putting a sail on it, and add steering. Being able to balance while the wind is pushing it would be the ultimate challenge for the design I think. And you get something you can drive around.
You should record the pid output and make a rolling graph alongside your video recording. I'm especially interested in seeing it relax while the thing is rolling, and spiking when pushed.
An idea for you is to motorize it and then while its moving, you can minimize how much power is being used by the Gyro and redirect that power to the forward moving motors. Whats your thoughts on this?
Amazing James! I had a lot of concerns about that and you help me to clarify many of them. I have a project/dream to create a real size electric bike using this principle to keep it always up, without physic stands. This video will can help me. Thanks bro!
Have you done any testing where the center of the gyroscope had a spoked design. You would be decreasing mass, but also increasing its moment of inertia such that it should be able to counteract the change in mass. Love the work your doing!! Can’t wait to see more.
Wow, that is working really well. Yes, it would be amazing to see a one-wheeled version working. Sorry, noob questions here: What happens if each gyro would run at different rpm? Could that possibly used to control the yaw?
With the automatic set point adjustment, can you now remove the weights taped to one side and have it automatically find the balance point (which might not be perfectly vertical)?
As always your robots are really beautiful. I would appreciate it if you could please make more in depth videos that cover programming in the context of robotics and explain more of the designing process on Fusion 360 or in general. Thanks for sharing your work!
Hey! Enjoying all these videos for sure, but this one inspired for me an idea, and for you a challenge: Build those gyros into the wheels on clutches, so that they drive the vehicle when engaged, and when it comes to a stop it remains upright. Obviously my brain jumped ahead to the 2 wheel car at this point, but you might want to perfect the concept before contacting Tesla! 😁
I see you do robots, you are very good at it. This mechanism could be useful to encourage people onto stable electric motorcycles or whatever we call them in the future. They would stay balanced while stopped and the inertia of the balancing wheel could be use to propel the cycle forward.
If we add a kinetic steering system (use the giros to tilt and let the kinetic steering rotate the wheels) and motorize it could become a nice little remote controlled motorcycle
I was just wondering about something like this yesterday- I was thinking about making a self balancing bicycle. Judging by the size and weight of those gyros it would be quite large to be able to balance a bicycle.
on the international space station... when the CMGs get to the point where they can't exert force any more, we call that "Saturation". There is some automatic communication to the russian thrusters to do a "de-saturation" which can get the CMG axes back where they have control authority again.
CMGs? Or reaction wheels? Does a CMG actually have a saturation limit except for how much force it can apply? Like sure if you just rotate it continuously you'd be able to apply a continuous force, up to the point where the motor rotating the gyro around an axis perpendicular to the primary weight-spinning axis hits its maximum speed. Even at that point, you'd still be applying a force, just not enough for whatever is requested, presumably.
@@clonkex yes, CMG and you are right, at some point you lose a degree of freedom. You can read more about them here: en.wikipedia.org/wiki/Control_moment_gyroscope#International_Space_Station
It's interesting you say that a bike stays upright on its own when it moves , if the steering is fixed it will fall over immediately no matter how fast it's going
"LIT" motors had a car called the "C1". This was a self balancing car that they spent years of research on. It used a CMG that seemed to work well. I'm don't know why they don't licence their CMG technology to other companies.
I was hoping you would make it a one wheeled robot and then you mentioned it. Would be cool to have both gyro and motorised wheel to balance in the different axes. But With one single wheel wit will probably spin around the vertical axis as well with only a single point of contact. So maybe a reaction wheel for a 3rd type of rotational control so you have 3 different rotational cotrol mechanisms for the 3 axes of rotation?
please build one with high center of mass since it will act like a reverse pendulum and will take more time to fall over, thus giving more time for the balancing gyros to correct. i think it could be more stable for the same reason balancing a broomstick on its end is easier than balancing it on the middle.
Could you mount a reaction wheel perpendicular to the gyros? when the gyros drift near to their end stops, use the reaction wheel to temporarily negate the force of the gyros as they return to the center position. This would allow the gyros to essentially move continuously as they can quickly reset when they have nearly run out of travel.
I'll make a backpack version of it. Turn it on when I leave the pub heading home. Falling is a thing in the past. Would that work as a stabilizer for people with balancing issues? Could be a great application if so. Cheers

Gyros should be placed to spin in the horizontal direction, though to make turning possible at all..

Or a pedal-operated bicycle.

I was just wondering about something like this yesterday- I was thinking about making a self balancing bicycle. Judging by the size and weight of those gyros it would be quite large to be able to balance a bicycle.

This is awesome! I'd love to see it motorized and also have the front wheel turn so you can drive it around.
Would the wheel need to turn? You could turn by doing the lean? ( Not a very tight turn )
@@noloafingwgas when you lean, you can counter turn to turn more aggressively, just like a motorcyle
Big fan James Bruton ❤️
I love your all projects
They are very helpful ☺️
on the international space station... when the CMGs get to the point where they can't exert force any more, we call that "Saturation". There is some automatic communication to the russian thrusters to do a "de-saturation" which can get the CMG axes back where they have control authority again.
CMGs? Or reaction wheels? Does a CMG actually have a saturation limit except for how much force it can apply? Like sure if you just rotate it continuously you'd be able to apply a continuous force, up to the point where the motor rotating the gyro around an axis perpendicular to the primary weight-spinning axis hits its maximum speed. Even at that point, you'd still be applying a force, just not enough for whatever is requested, presumably.
@@clonkex yes, CMG and you are right, at some point you lose a degree of freedom. You can read more about them here: en.wikipedia.org/wiki/Control_moment_gyroscope#International_Space_Station
Would be cool to motorize the wheel for forward motion and have the robot turn direction by adjusting the roll angle with the gyros.
It's interesting you say that a bike stays upright on its own when it moves , if the steering is fixed it will fall over immediately no matter how fast it's going
"LIT" motors had a car called the "C1".
This was a self balancing car that they spent years of research on.
It used a CMG that seemed to work well.
I'm don't know why they don't licence their CMG technology to other companies.
balancing unicyclebot sounds awesome!
I was hoping you would make it a one wheeled robot and then you mentioned it. Would be cool to have both gyro and motorised wheel to balance in the different axes. But With one single wheel wit will probably spin around the vertical axis as well with only a single point of contact. So maybe a reaction wheel for a 3rd type of rotational control so you have 3 different rotational cotrol mechanisms for the 3 axes of rotation?
please build one with high center of mass since it will act like a reverse pendulum and will take more time to fall over, thus giving more time for the balancing gyros to correct.
i think it could be more stable for the same reason balancing a broomstick on its end is easier than balancing it on the middle.
Speaking of motorcycles, you should make a robot bicycle that countersteers
Could you mount a reaction wheel perpendicular to the gyros? when the gyros drift near to their end stops, use the reaction wheel to temporarily negate the force of the gyros as they return to the center position. This would allow the gyros to essentially move continuously as they can quickly reset when they have nearly run out of travel.
Your outro song has me half expecting you to scream walterific at the end. He has used it for a long time lol.
If you put quad skate bushings on it you can get it to turn by leaning
Amazing video !
I'll make a backpack version of it. Turn it on when I leave the pub heading home. Falling is a thing in the past. Would that work as a stabilizer for people with balancing issues? Could be a great application if so. Cheers
