Biped balance and Low Cost Gyros: experiences? which one to use?

Hi Matthias, I have used the Murata ENC-03J rate gyros. I got mine from androidworld.com. They have proven to be very reliable.

For what you are doing you will need to merge a stable vertical reference from an inclometer (sp?) or accelerometer with the rate roll from the gyro.

I have done this in a small balacing robot quite successfully.

Look for "complementary filters" or if you're into maths "Kalman filters". The rotomotion project on source forge is a very good starting point. The other thing is to search on ballancing robots and read up on their various approches. Nbot & Gyrobot are 2 that spring to mind.

Where did you get pricing on the gyration ones? They only seem to sell end products on the site.

Regards, Robin

Phew, 50 Euros per angle. I knew it would not be cheap ;-)

Cool. Good to know that it does work. Thanks for that jump start. I'll dig into what I find.

I did not get pricing, but I assumed that they would do wholesale since the describe many details about the actual component. The probably want to sell numbers. I will give them a call anyway... .

Thanks again,

Matthias

Plese follow up with the pricing info when you get it.

Thanks,

I think these are usually salvaged from Gyropoint mice available on eBay for, typically, about $20.

More information on the Microgyro 100 is here:

You can buy a MicroGyro 100 starter kit for $450 here:

I got into contact with them and they were very friendly and helpful. I am getting the eval kit and I will post my experiences with it as soon as I have tried out some stuff.
