Almost all conventional biped humanoid robots have difficulties in realizing various walking motions such as knee stretch walking like a human because of an insufficiency of DOF. Therefore, we have developed a 16-DOF biped humanoid robot without a trunk: 3-DOF in each ankle, 1-DOF in each knee, 3-DOF in each hip and 2-DOF in the waist. Using the biped robot, basic experiments are conducted and the effectiveness of the leg mechanism is confirmed.

This paper describes a new leg module for biped locomotors. We have developed a biped locomotor, WL-15 (Waseda Leg 15), which is applicable to various fields, such as medical, welfare and entertainment. WL-15 consists of parallel mechanisms such as a high stiffness, high positioning accuracy and easily calculated inverse kinematics. A walking control program is created on the basis of Simulink and RT-LAB executed on Windows NT and QNX target system. Using WL-15, dynamic walking with the step time of 0.8 [sec/step] to 1.92 [s/step] and turning step of 90 is conducted, and the effectiveness of WL-15's parallel mechanisms is confirmed.

This paper describes a macro-walking instruction strategy for a biped humanoid robot to memorize complex walking patterns systematically and effectively. In teaching various walking motions, auditory sensors are employed. Based on the sensory information, the motion of lower-limbs is created in online by a pattern generator. At the same time, the motion of the trunk and the waist is generated in online by a balance control method for walking stability. A complete walking pattern is hierarchically constructed on the basis of basic and advanced walking patterns. Using WABIAN-RV, many experimental tests are conducted, and the effectiveness of the teaching strategy is verified.

In this paper a humanoid robot named as WABIAN-RIV (WAseda BIpedal humANoid Refined IV) is analyzed in terms of stiffness characteristics. This paper proposes basic models and a formulation in order to deduce the stiffness matrix as a function of the most important stiffness parameters of the WABIAN architecture. The proposed formulation is useful for numerical estimation of stiffness performances.
