Swiss scientists have proposed that if robots could evolve through natural selection the result would be robots that would help each other, cooperate, and be capable of hunting. Their experiments follow on from earlier studies reported by PhysOrg, which used robots to shed light on evolutionary processes.

Researchers Laurent Keller, from the University of Lausanne, and Dario Floreano of the ?cole Polytechnique F?d?rale de Lausanne studied Alice and Khepera robots controlled by input information from the robots? sensors and neural networks. They loaded short basic instruction codes into the robots? operating systems, with random variations that changed every generation, in "virtual mutations". To simulate natural selection, only the code for the most successful robots was selected and passed to the next generation of robots.

In one experiment they programmed robots with six sensors on one side and two on the other to navigate a maze. They then selected the robots most skilled at avoiding collisions. After fewer than 100 generations the robots could navigate through a complex maze without collisions, and had learned to keep the side with six sensors facing in the direction of travel.
