Abstract
A left leg unit includes a vertical piece; a horizontal piece; a vertical guide groove; a horizontal guide groove; an outer coupling bar to which the vertical piece and the horizontal piece are rotatably coupled, thereby coupling the vertical piece and the horizontal piece to each other; and a pedal that is rotatably coupled to the outer coupling bar. The vertical guide groove and the horizontal guide groove are extended in such a way that they intersect with each other. A rotation axis of the pedal is disposed away from a rotation axis of the vertical piece and a rotation axis of the horizontal piece and is disposed away from a midpoint of a line that connects the rotation axis of the vertical piece and the rotation axis of the horizontal piece, whereby the rotation axis of the pedal moves along an elliptical trajectory.
