Reading wheel encoders

Hi folks

I’m looking for an efficient way to read wheel-encoders and have read a bunch of articles on the subject.

Including OddBots very fine article: http://letsmakerobots.com/node/24031.

My first idea was to use an old pc mouse utilizing ps/2 library with arduino. I made some mechanical parts to let mouse encoder shafts read the rotations of the wheels.

Can one Arduino resent serial com to another Arduino?

 

Can one Arduino receive serial communication via USB and then resent it to another Arduino via tx rx pins?
