Control Algorithm for Stable Walking of Biped Robots

This paper deals with the stable walking of biped robots. The presented control algorithm enables a biped to perform stable walking without using any precomputed trajectories. The algorithm merges gait trajectory generation and control, and can be used for global control, for local control along an existing trajectory as well as for online computation of gait trajectories for stable walking. The inputs for the algorithm are a few parameters such as walking speed and step size. The performance of the algorithm is demonstrated by simulation.
