The experimental results show that the gait planning method used in this paper is highly feasible.Īldebaran Robotics (n.d.) NAO Software documentation.

Finally, the correctness of the gait planning is verified by the Webots Platform for NAO simulation and its real operation. In the three-dimensional stairs, the visual system of the NAO robot was used to perceive its surrounding environment, and then the image processing technology was used to identify the position of the stairs. The inverted pendulum model is used to plan the forward gait of the robot, and then the start and stop gaits of the robot are planned respectively and meanwhile we proposed the zero-moment point stability judgment and the supporting polygons control to determine whether the robot is in a stable state. Firstly, the NAO robot is modeled by the kinematics then it can be understood the humanoid robot itself after the gait characteristics and human walking patterns according to the characteristics of the stairs, and the geometric constraints of the robot’s walking gaits on the stairs are analyzed further then the robot’s lateral gait is planned through a first-order linear inverted pendulum model, and the variable length model is used. As a typical example of a special ground, this paper proposes a dynamic planning method for the gait planning problem of the humanoid robot NAO climbing and down stairs. The humanoid robots have similar human feet, but due to the limitations of joint freedom, they are difficult to walk on the special ground like humans, so planning an effective walking method applies on these special grounds becomes of critical importance.
