The default settings used for the test programs 
on the NXT and for many sample programs in the 
Robot Educator are as follows:
Port A: Motor or a Lamp for an extra function
Port B: Motor for movement; for a two-Motor 
chassis, often this is the left side.
Port C: Motor for movement; for a two-Motor robot, 
often this is the right side.
