Abstract: An arm assembly of a robot includes a servo coupled to the chest of the robot, an upper arm driven by the servo, a forearm rotatably coupled to the upper arm, a hand connected to an end of the forearm and rotatable about a first axis extending along a lengthwise direction of the forearm; and a hand transmission mechanism configured to transmit motion from the servo to the hand so as to drive the hand to rotate about the first axis.

Abstract: An assembly for driving a waist of a humanoid robot to rotate with respect to a chest of the humanoid robot includes a support assembly fixed in the chest, a servo mounted to the support assembly, and a rotating member fixed to the waist and rotatable when driven by the servo.

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.

Abstract: An arm assembly includes a servo coupled to the chest of the robot, an upper arm driven by the servo, a forearm rotatably coupled to the upper arm, and a forearm transmission member comprising a first end rotatable with respect to the chest and a second end coupled to the forearm. The upper arm, the forearm and the forearm transmission member are arranged in such a way that the forearm rotates when the upper arm rotates with respect to the chest.

Abstract: A head of a robot includes a head housing, a lace panel connected to the head housing, a mask moveably connected to the head housing, a mounting frame arranged within the head housing, a first servo connected to the mounting frame, and a first transmission mechanism to transmit motion from the first servo to the mask so as to move the mask between a first position where the mask covers the face panel and a second position where the mask is lifted to expose the face panel.
