Re: What is a Enocder sensor ?
While it is true that you can be pushed backwards while trying to go forewards, using the encoders in a quadrature state requires more processing power (interrupts). If you are only using the encoders during autonomous, it is not overly likely that another robot will be on your end of the field, and the extra processing power may come in handy.
Furthermore, even in other situations, if you try to implement some kind of PID control, the processing required may mean that you will simply need to risk getting pushed backwards.
