Camren,
Could you fill us in on exactly what your thoughts on this might be? You can contact me via the PM feature if you do not want to give away a design idea. I can think of a few ways an alternator might be used legally on a robot but without specifics, I can't really give a blanket opinion.
If your application is simply to gain power from the energy of a robot in motion, there are significant losses in such a system that make it impractical. If the game played on the side of hill, we might be talking some real gains.
