 Bigger Bigger  Smaller Smaller  Reset Reset

I have been working on a senior project that involves communicating an Arduino board to a phone. Now I was going to use the Arduino ADK but because of dimensions issues I have to make my own print circuit board. I have been comparing these two boards and found that the Arduino has an extra microprocessor. I didn't know what its purpose is for and was hoping someone could help.
