ONE of the most important properties that one can expect from humanoid robots is their fast and fluid walking in an environment that is rather adapted to humans. In this context, the generation of dynamic movements and control of bipedal locomotion, both theoretically and experimentally studied by many researchers, are still fundamental to improve. The aim is to make functional these humanoids and give them a genuine ability to adapt to changing environments through reactive and predictive skills. One of the main challenges is to enhance the walking motion for slow displacement or at the best in highly dynamic stable walking, even in perturbed
terrain through reactive and adaptive capabilities based on sensor measurements. For many years, sensors have been used
