Let's Make Robots!

OK, I have just given up making a balancing robot. Ever.

Making a balancing robot - or even dreaming of making one just lost it's appeal.. because I will never make anything like this.,

Well, all.

I'm making a two-wheeled balancing robot as a step towards making a single-ball balancing bot. I've seen the single ball bot (in pictures) for over 10 years, and it hasn't discouraged me yet.

As long as your motors are strong enough and your control loop fast enough, it should be easy to get a two-wheeled balancing bot to just balance. I now have most of the parts and will start programming shortly. And I have a pair of more powerful motors that I can use if the Pololu ones that should arrive tomorrow don't work.

Then maybe when I save enough for the motors and wheels I can attempt to build a single-ball bot. The one thing I can't figure out is how they get the equivalent of wheel encoders, since they are necessary to keep the bot on station. Perhaps a mouse chip that is placed close to the basketball?

Now, if somebody comes out with a levitating bot, that might discourage me for a bit. :)

While it is major league coolness, all that work to balance has to chew through batteries like crazy.... 

Get 6 axis chip, an accelerometer 3 motors and you could pull it off easily

the code would seem faily simple

All you'd have to do is track the offset of a <0,0,0> axis' and balance it out via the motors depending on the accelerometer force.


OK, let's see it then!

I wanted to do it, I haven't got the funds to make it.

I'd love to see the algorithm that does the positioning. Must be some pretty fancy PID :)

why dont you make a tutorial on how to make this?

He did not make this therefore a tutorial from him would not be possible.

If i ever get the parts required to make it i'd for sure post a tutorial.

It's a shame that we have some negative people posting like i have the funds to build it....

Looking at it can be assumed as quite advanced hardware/software. It's actually not that hard to wrap your head around.

I promise if i ever get the chance to work on this kind of project i'll help you all build one.


Why would you give up, I dont think we ever talked much here, but I have alot of respect comming your way from you Candian brother. So here is the question, so how do I help to keep this dream alive?
