Asymmetric Swing-Leg Motions for Speed-Up of Biped Walking

[abstFig src='/00290003/04.jpg' width='120' text='Stick diagram of limit cycle walking with asymmetric swing-leg motion' ] This study presents a novel swing-leg control strategy for speed-up of biped robot walking. The trajectory of tip of the swing-leg is asymmetric at the center line of the torso in the sagittal plane for this process. A methodology is proposed that enables robots to achieve the synchronized asymmetric swing-leg motions with the stance-leg angle to accelerate their walking speed. The effectiveness of the proposed method was simulated using numerical methods.
