Conclusion This paper discussed an important issue related to legged robots the kinematics and dynamics model of the quadruped robot. The analysis done for each model was always presented in two parts the platform and the legs according to a time-varying topology and a time-varying degree of freedom of the system. Several methods were used in each modeling process always trying to use those which brought to better performance in accordance with the topology modeled and that could be easily implemented in programming languages of high level. Then were used the Denavit-Hartenberg parameters for solving the direct position kinematics of the platform and leg the Principle of Virtual Work or the d Alembert for dynamic modeling of the platform and the Newton-Euler dynamic model for leg in the .
