Stability during the biped locomotion and especially humanoid robots
walking is a big challenge in robotics modelling. This paper
compares the classical and novel methodologies of modelling and
algorithmic implementation of the impact/contact dynamics that
occurs during a biped motion. Thus, after establishing the free
biped locomotion system model, a formulation using variational
inequalities theory via a Linear Complementarity Problem then an
impedance model are explicitly developed. Results of the numerical
simulations are compared to the experimental measurements then the
both approaches are discussed.

biped locomotion system model, a formulation using variational
