Hello, i have just started learning robotics and I'm allready stuck. Since i live in a place that has only 1 store with DC motors (no servos), and i can't buy stuff on line i need your help.
These are the motors I'm looking at (the link will shrink your browser window, sorry about that):

LEFT 2400 rpm", and the second one "MOTOR 9V
RIGHT 2400rpm".
This is where I'm stuck. Reading
THIS article i learned that "DC motors are non-polarized - meaning that you can reverse voltage without any bad things happening" and that "if you want to control which direction the motor spins, you reverse the wires".
So why would it say that the motor is "left" or "right" if i can just reverse the wires? Or am i looking at the wrong motors?
It may seem as a dumb question, but i would really appreciate if you could help me since I'm just getting started. Thanks in advance!
