Hi ^^
I wanna build a pendubot for my university.
I decided to use rotary encoders for an absolut angle measurement.
But the problem is, i can't find any contactless rotary encoder, does anyone know where to buy them ?
I can't use a Potentiometer or sth like that, because of the friction.
This is a Pendubot:

Thanks

Not sure if this fits your budget, but these guys make really nice optical encoders: http://www.microesys.com/

They tend to somewhat expensive for hobbyist use, say $50 and up. However if you search out E-bay you can find bargains once and awhile:

Hi,
thanks for your replies^^

I found some encoders by clicking on a shop advertiding button on ebay .

Don't know why Rotary Encoders are hard to find and Gyros you can find anywhere ????
