 For our micromouse project we have decided to use dc reversible motors. We
 are trying to figure out what voltage and current ratings are typical
 for a project like this. It seems like 6 AA batteries would suffice.     
 Our understanding of motors is quite limited, apparently control (for
 permanent magnet motors) is usually done by varying the armature voltage
 there seems to be a linear relationship with speed and this voltage. But
 how about current? how does one go about calculating what will provide
 enough torque to move the motors under the mouse's load?
 
  Any contribution will be greatly appreciated. Please respond directly
  I will post a summary if people are interested.
  
  Thanks in advance,
  Kenn.
