Comparison of bipedal humanoid walking with human being using inertial measurement units and force-torque sensors

Abstract

WABIAN-2R is a bipedal humanoid robot which is capable of stretched knee walking with heel-contact and toe-off motions due to the presence of a 2-DoF waist and a passive joint for bending toe motion, and can thus mimic human-like walking. This paper aims to determine the similarity between the walking gait of WABIAN-2R to the natural walking gait of a human of comparable size and stature, on the factors (i) pelvic tilt, (ii) pelvic rotation, (iii) swing and stance percentage, and (iv) double limb support and single limb support percentage using inertial measurement units and force-torque sensors.
