Typical human-based biped robot has 12-DOF for its legs, but there may be another approach not to take a model on human, but to design function oriented. To design a practical light-weight biped, reducing a number of DOF is one of the most efficient method. This paper discusses minimum number of DOF for various cases, where 4, 7, 5 is the resultant minimum number of DOF for horizontally composed terrain, uneven terrain with normal leg exchange sequence, uneven terrain with partial leg exchange sequence, respectively. This paper also shows practical designs of bipeds with 5, 8, and 6-DOF. Trial manufactured machines based on these discussions could show good performances on stairs and uneven terrain.

From 1970's, legged robots have attracted much attention of many researchers. In spite of this, it has been regarded that dynamically stable walking is very difficult to be tackled for any types of legged robots. For a trot gait for quadruped walking robots, we have proposed “the sway compensation trajectory”. This method utilizes a lateral, longitudinal, and vertical motion of a robot body to keep a zero moment point (ZMP) on a diagonal line between support legs. In this paper, we develop the sway compensation trajectory for a biped robot, and show that dynamically stable walking is realized. This method makes it quite easy to design stable ZMP and COG (center of gravity) trajectories, which have been regarded as a very complicated and delicate problem. The effectiveness of the proposed method is verified through computer simulations and walking experiments by a humanoid robot HOAP-1, and YANBO-3.
