                 robot has been studied, combining structural and
                 parametric modifications of the system responsible for
                 generating the gait. The experiment was conducted using
                 a small 17 DOF humanoid robot, whose actuators consist
                 of 17 servo motors. In the approach presented here,
                 individuals representing a gait consisted of a sequence
                 of set angles (referred to as states) for the servo
                 motors, as well as ramping times for the transition
                 between states. A hand-coded gait was used as starting
                 point for the Optimization procedure: A population of
                 30 individuals was formed, using the hand-coded gait as
                 a seed. An evolutionary procedure was executed for 30
                 generations, evaluating individuals on the physical
                 robot. New individuals were generated using mutation
                 only. There were two different mutation operators,
                 namely (1) parametric mutations modifying the actual
                 values of a given state, and (2) structural mutations
                 inserting a new state between two consecutive states in
                 an individual. The best evolved individual showed an
                 improvement in walking speed of approximately
