encoders/gyros/potentiometers

[nehalita]

okay, from what i know, encoders, gyros and potentiometers - they are very useful to programming.

has anyone managed to do the autonomous code without using these?

and if we were to use them, where exactly does each part go? i know the potentiometer is for the arm, but where exactly?

where does the encoder and gyro go?

and which encoder/gyro/potentiometer did everyone use? i looked up the encoder from grayhill (61k/4k) and most of the places were sold out. i finally found one but it was a 61k256 which is too much, we just want a 61k64 and that too it was like $70+! we want something cheap and still useful.

thnx. i looked all over but most forums touched on the topic. hopefully this will help ppl with the same qs.
