An extended Teager study of vibration detection for industrial robot under low sampling resolution

“…[5][6][7] As is studied, transmission system of industrial robot possesses similar vibration characteristics just like other rotatory machines -fault condition could be well observed via vibration signal. 8 To achieve such vibration detecting, it mainly involves in three steps -raw data acquisition, feature extraction (single or multi-variants) and condition evaluation. Firstly, medium for acquiring raw vibration data is various.…”

Optimal Placement of Vibration Sensors for Industrial Robots Based on Bayesian Theory

“…In the past 30 years, fault monitoring and diagnosis methods for various nonlinear systems and robotic systems have been studied. Model-based analytical redundancy methods have been used for fault detection and isolation of nonlinear and robot systems [1][2][3].…”
