We have been using the ZMP (Zero Moment Point) as a criterion to distinguish the stability of walking for a biped walking, robot which has a trunk. In this paper, we introduce a control method of dynamic biped walking stabilized by trunk motion compensating for the three-axis moment on an arbitrary planned ZMP. We developed a biped walking robot WL-12 RV (Waseda Leg-12 Refined V) and perfomed a walking experiment with WL-12 RV using the control method. As a result, we realized fast dynamic biped walking (walking speed 0.54 s/step and step length 0.3 m) on a flat floor. This walking speed is about 50 percent faster than that with WL-12 (Waseda Leg-12) which compensates for only the two-axis (pitch-axis and roll-axis) moment by trunk motion.
