i want to start working on a "path remembering robot" project(1st project).
the idea is to know and save how much revolutions each wheel(2 wheels) had made from start to finish and speed of turning..
therefore i need to know more about wheel encoders, since im new to this stuff(first time to use it) - could you tell me which types i'll need, what is their output and how to analyze the output to know the distance/speed..
finally, is there another suggestions on how to remember a path and store it??
thanks your help will be very appreciated.
