Now if you have only one robot, then you would have to run it 10 times to get one generation of population 10. Clearly, you could not go through a large number of generations.
But if you can model the important aspects of the robot for whatever fitness function you have in mind, then you can evolve in the PC, and just put one ANN into the robot. m -- I'm proud of http://ANNEvolve.sourceforge.net.
