Limb and body mechanism for humanoid robot

The invention discloses a limb and body mechanism for a humanoid robot. The limb and body mechanism comprises a main body, a left arm, a right arm, a left leg and a right leg, wherein the top ends of the left arm and the right arm are both fixedly connected with the main body; the bottom surface of the main body is connected with the top surface of a third movement platform; the third movement platform is connected with the base of a body part through a seventh movement chain and an eighth movement chain; the bottom surface of the base of the body part is connected with the left leg and the right leg; the left arm, the right arm, the left leg and the right leg are series-parallel humanoid robot arms which consist of same components. The robot arms of the limb and body mechanism are simple and compact in structure and low in production cost; the series-parallel humanoid robot arms are flexible in movement, high in bearing capacity and low in inertia; the humanoid robot acts in a plurality of postures; the stability is high; the machining and assembling process is good.
