Some of Bongard’s tests involve identically impaired robots that can wirelessly share information about their simulations with each other and with a central computer. Despite running the same software, different robots develop different walking styles, Bongard says, because each robot can choose from tens of thousands of possibilities. In one set of tests, the robots sent disability data to the central computer, which tried to develop a single walking technique for all of them. But the barrage of incoming data bogged the computer down. It was more efficient, Bongard says, to let the robots think for themselves and then compare their simulations.
