Robots learn to cheat each other to get ahead

When it comes to survival, its seems robots are just as ready to deceive one another as humans. In a scene imagined in countless science-fiction movies they evolved the ability to lie in order to stay alive.

The football-sized machines were were designed to cooperate with each other to find a 'food source' and avoid a 'poison source' inside a special arena.

In the film iRobot machines were able to deceive their human masters, now scientists have proved robots can learn to lie

Each was programmed to show a blue light when they found a food source and robots scored positive marks for finding and staying by it.

But scientists at the Laboratory of Intelligent Systems in the Ecole Polytechnique Fédérale of Lausanne, France, had limited the space around the food source so that not all the robots could reach it to feed. The 200 highest-scoring robots were then randomly 'mated' to produce a new generation of programming.

After nine generations the robots had learned to follow the blue signals of others who found food, pushing and shoving to get to the source. By 500 generations, 60 per cent of robots had learned to keep their blue signal light off when they found the food to stop other machines muscling in on their resource.

'Evolutionary robotic systems implicitly encompass many behavioral components, thus allowing for an unbiased investigation of the factors driving signal evolution,' the scientists said. Their research appears in the journal Proceedings of the National Academy of Sciences.
