Current sensing on the Arduino Robot

Hi,

I bought an Arduino Robot and would like to keep track of the current drawn by the 2 motors.

On the website: http://arduino.cc/en/Reference/RobotLibrary, it says the RobotLibrary has the functionality to sense the current used by the 2 motors. Unfortunately, I wasn't able to find out how to do this.

Could someone please point me in the right direction?

Many thanks in advance :slight_smile:
