Abstract
A leg assembly of a robot comprising a waist includes a thigh rotatably coupled to the waist, a lower leg rotatably coupled to the thigh, a foot rotatably coupled to the lower leg, a servo fixe to the thigh, a first transmission mechanism configured to transmit motion from the servo to the thigh to drive the thigh to rotate with respect to the waist; a second transmission mechanism configured to transmit motion from the thigh to the lower leg to drive the lower leg to flex when the thigh move upward and extend when the thigh move downward; and a third transmission mechanism configured rotatably connected to the thigh and the foot in such a way that the foot dorsiflexes from an original position when the lower leg is flexing and rotates back toward the original position when the lower leg is extending.
