Neural network that mutated randomly has been controlling the robots, with input information from the sensors of the robots. In an imitation of natural selection, the robots with the best manipulating abilities were allowed to promote a new generation. Furthermore, having their neural net connections mixed and passed to a new generation paired selected robots.

It is being considered that within 100 generations, the robots would start moving through mazes, without even bumping into anything. Robots were found to cooperate in pushing larger tokens together to earn points for their whole group. The researchers have also observed altruistic behavior, in which robots would sacrifice getting points for themselves in favor of getting points for their whole group of related robots.
