U have no idea

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.

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.

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 truly admire your knowledge and experience in so many science branches

Man ive had a lil thought bubble for a gyroscopic motorcycle and this is a large step in that vision, well done

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.

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!

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!

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!

This is a really good design.

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".

Wow, that's frickin sweet!

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!!

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?

James Thank so much for everything! Would it be possible to share your Cura settings for your red PLA. I have a huge problem with red PLA lifting from my luzabot heated plate. Thank you for your time

It's just ausam piece of engineering by one of very smart engineer. 👌

One wheel robot sounds awesome!

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

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.

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)?

Nice !

That's very cool.

Brilliant. There's also a motorcycle that stays upright using gyros when you get off.

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.

But once this gyro is rotated perpendicular to the robot it doesn't have any control authority anymore, so effectively there's still an endstop

Incredible :)

Could you not use gyroscopic inertia to propel it forward/ backwards? Or would that have to be mounted on a different axis,

This is awesome! I'd love to see it motorized and also have the front wheel turn so you can drive it around.

It would be cool to build a system like this with a drive wheel in back and the gyros over the front wheel, using leaning to turn.

Sir, your cable management is supreme. Just wanted to point it out.

Which PID lib do you recommend? I'm struggling with one of the common ones (AutoPID i think) for a cooling fan. It eventually fails and does nothing.

This could be a pretty wild set of roller blades

I do both gyros and servos. Great job by the way. You do realise that you could also use a flywheel...which could double as a kinetic battery source.

So the extra code which accumulates the controller output and adjusts the set point if it's consistently turning in one direction... isn't that what the I term of a PID controller is meant to do, or is it some kind of double integral term?

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. 👍👏👏👏👏

Put that mechanism in a big wheel it would look so good

Great work, I do love a balancing robot, No 3D printers when I made Earwig .

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.

Hi @James. I am curious to understand if this concept be applied to create a robot that can balance and run a wave board?

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.

What would happen if you decided to equipt this robot with motors and a "steering wheel"? Would driving a long and constand curve (basically circles) cause the center balancing point to be shifted due to centrifugal forces and Still keep the whole robot upright? If the robot stopped (or drove a streight line) would the balancing point return to "normal" again quickly or would you expect some issues with that?

During driving it balances better so could you dial down the compensation and thus save battery life?

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!

@Teth47

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

How would a small tilt or incline affect this? Interesting project though, thanks!

It is perfect !!!

Your outro song has me half expecting you to scream walterific at the end. He has used it for a long time lol.

You need to build a lathe and a balancer to make sure everything is round and balanced for high speed parts. This is so cool!!!

Bonus fact: A lot of the science behind this is basically how they control, rotate, and adjust the orbit of the International Space Station.

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.

excelente

Please do reaction wheel balancing stick, that would be very interesting of this series and makes this balancing series complete...

I wonder how well you could get it to ballance on a single point by giving those two gyros a second axis of tilt each. Might work as a stabilization method for a future biped?

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.

Would you ever consider finding the transfer function equivalent equation for it to implement a LQR controller?

I wonder about the forces on the 3D printed surfaces, did you calculate that? I can see PLA shatter with just too much.

In line with the roll-amplifying gyroscopic boat correction, I have an idea on how one could make rollerblading very difficult...
