This invention relates to a hydraulically driven humanoid robot pelvis, within the field of humanoid robots. It addresses the problems of complex structure and large size in existing hip joint pelvic structures. The pelvic support frame integrates printed hydraulic circuits. A lumbar joint base is mounted on one side of the pelvic support frame along its length. Two hip joint mounts are symmetrically mounted on either side of the pelvic support frame along its width, with the axis of the hip joint mounts aligned with the width of the pelvic support frame. The thickness of the pelvic support frame is less than the outer diameter of the hip joint mounts. A lumbar joint is mounted on the lumbar joint base and drives the pelvic skeleton to achieve posture adjustment. Each hip joint mount contains one hip joint, enabling roll and yaw movements. Each hip joint is connected to a thigh, and the pitch movement of the pelvic skeleton is achieved through the drive of a hydraulic cylinder on the thigh. This invention is applicable to robots that need to carry heavy objects or perform tasks requiring great strength.
