Bipedal robots have a certain adaptation to a wide variety of surfaces where humans do the essential to live and work, a clear example can be seen when transported objects where we notice the recovery and movement in dangerous environments, among others. The main objective of this study is the development to make a mathematical model of the kinematics of a biped robot. Keywords: Biped;quaternions;kinematics;mechatronics;adaptation;inclination
