I am building a differential drive robot from an old powered wheelchair. The wheels are attached to the motor by a ~10:1 gearbox. I would like to add encoders to the motors. what kind of encoders should I use. I am running a full PC onboard. I have a chip kit max32 that I could use as an interface. What is the best way to add encoders. Is there a useful usb interface? What kind resolution should I look at. The motor drivers I am using do not have encoder feedback. Thanks for any feedback.

At full power the robot can move about town miles an hour. Is it typical to use a dedicated device just to read the encoders? A device like"http://www.robotshop.com/phidgets-phidgetencoder-highspeed-usb-4-input-2.html"

My other question is, what hardware do you guys recommend. 200 CPR encoder connected to an arduino?
