Method and system for predicting life cycle of SCARA robot

The invention discloses a method and system for predicting the life cycle of an SCARA robot, and relates to the technical field of robots, and the method comprises the steps: collecting acceleration vibration signals in the operation process through four acceleration sensors disposed on a robot arm of the SCARA robot; the acceleration vibration signals obtained by the four acceleration sensors are preprocessed to extract vibration signal feature vectors; taking each wavelet packet energy spectrum entropy vector as an input vector of the corresponding neural network, and obtaining a life cycle prediction result corresponding to each wavelet packet energy spectrum entropy vector; and life cycle prediction results under the four-way wavelet packet energy spectrum entropy vectors are processed, and the life cycle of the SCARA robot is obtained. The life cycle of the SCARA robot is predicted by collecting the acceleration vibration signals of the four joints, so that the reliability and precision of the life cycle
