Abstract :
It has been shown that the use of cyclic genetic algorithms can be an effective means of gait generation for hexapod robot simulations. They can, with only low-level primitives, produce reasonable gaits in minimal time. In addition, their output requires little in intermediate controller complexity as it is a sequence of these primitives, which can be fed directly into the robot. In this paper, we test the applicability of these algorithms on an actual robot. A model for simulation was produced based on the measured capabilities of the Stiquito robot. This model was trained with the CGA using five random initial populations; gaits quickly evolved for all five. Tests on the actual semi-autonomous robot showed that after 1000 generations gaits comparable to the best designed by human engineers were produced
