The invention discloses a robot integrated joint unit and a foot type robot applying the same, and belongs to the technical field of robot joints. An existing double-joint line arrangement mode influences structure safety and attractiveness of a robot, a wire is easily damaged, and the service life of the wire is influenced. The robot comprises a first motor, a speed reducer assembly, a second motor assembly, a second speed reducer assembly and a first output connecting rod. Double motors of double joints are located on the same side of the joints, and the situation that a motor power cable needs to pass through the joints is avoided so that the fatigue damage of the motor power cable can be effectively relieved, and the service life of the motor cable wire can be prolonged. The motor assembly and a joint connecting rod do not need to reserve a special threading hole and a cable arrangement mechanism, so that the structure is more reliable; the integration degree of the double-joint unit is further improved, the axial size of the joint unit is reduced, and the structure is more attractive.
