Acerca de

Fault detection is a topic of great relevance due to its importance in the control of various types of systems. In particular, the most common faults usually occur in actuators or sensors. This paper proposes the use of autoencoders for the detection of faults in the joint sensors of a robotic manipulator during trajectory tracking tasks. The proposed methodology addresses the identification of faults caused by disconnections, noise and blockage in the sensors of all the joints of the manipulator. In addition, a differential evolution optimization algorithm was implemented to select the optimal threshold that determines whether or not a fault occurs, which increases the accuracy of the system. The applicability of this approach is demonstrated by detecting faults in the sensors of a 5-degree-of-freedom (DOF) manipulator. The results obtained show that autoencoders are a powerful and versatile tool for fault detection in robotic manipulators, at least in most of their joints.
