Controlling a biped robot with several degrees of freedom is
a challenging task that takes the attention of several researchers in the
fields of biology, physics, electronics, computer science and mechanics.
For a humanoid robot to perform in complex environments, fast, stable
and adaptive behaviors are required. This paper proposes a solution for
automatic generation of a walking gait using genetic algorithms (GA). A
method based on partial Fourier series was developed for joint trajectory
planning. GAs were then used for offline generation of the parameters
that define the gait. GAs proved to be a powerful method for automatic
generation of humanoid behaviors resulting on a walk forward velocity of
0.51m/s which is a good result considering the results of the three best
teams of RoboCup 3D simulation league for the same movement.
