ABSTRACT
The locomotion of humanoid robots is essential for the development of new transport systems. It has to satisfy constraints of lower energy consumption to increase energy autonomy and meet the conditions of unilateral contact. It also has to ensure the orbital stability of walking despite disturbances such as model uncertainty, unstructured ground, or interactions with the environment. To eliminate these disturbances, we consider control strategies associated with the definition of reference movements. This article presents some basic control strategies and analysis tools for the orbital stability of a cyclic planar and 3D bipedal robot walk.

INTRODUCTION
The locomotion of humanoid robots is essential for the development of new transport systems. It must satisfy the constraints of reduced energy consumption to increase energy autonomy, and compliance with one-sided contact conditions. It must also ensure orbital stability despite disturbances such as model uncertainties, ground irregularities or interactions with the environment. To reject these disturbances, we consider control strategies that are associated with the definition of reference motions. Some basic control strategies and elements for analyzing the orbital stability of a cyclic walk of bipedal planar and 3D robots are presented in this article.
