The invention discloses an industrial robot capable of detecting the wear degree of joints in real time and belongs to the field of robots. The industrial robot capable of detecting the wear degree ofthe joints in real time. Through arrangement of fixed-point detection layers and under the actions of wear-resistant particles in pre-reminding layers, the time that wear occurs at the joints can beeffectively delayed. When wear occurs to one joint, sunken deformation can occur to one or both of an articular head and a articular fossa of the worn part, pressure data detected by two pressure sensors in the same balance detection layer can lose balance to generate a certain pressure difference. The wear condition can be judged according to the pressure difference. Meanwhile, the worn point canbe judged. When receiving a wear signal, a control system can control spines to pierce reminding inhibiting balls adjacent to the worn point. On the one hand, continuous expansion of the wear phenomenon is effectively suppressed, and on the other hand, working staff can be reminded visually of timely maintenance, and the service life is prolonged.
