Abstract: A method for the surface treatment of an article (2) by means of a robotic device (3) comprising a robotic arm (5) and a spraying head (4) fitted on the robotic arm (5); the method comprises a learning step, during which the operator moves the spraying head (4) by means of a handling device (9) and the movements made by the spraying head (4) are stored by a storage unit (8); and a reproduction step, which is subsequent to the learning step and during which the robotic arm (5) is operated so that the spraying head (4) repeats the movements stored by the storage unit (8).

Abstract: A method of predicting a fault in a rolling bearing, the rolling bearing including inner and outer rings and rolling bodies evenly angularly distributed therebetween, the method comprising: processing (in the DSP system 8) a position signal (x(t)) indicative of a relative angular position of the inner ring with respect to the outer rings, and a vibration signal (y(t)) (by the accelerometer 7) indicative of speed-related vibrations in the rolling bearing, such that they correspond to either an angular displacement of the rolling bodies equal to an integer number of angular gaps between adjacent rolling bodies or an integer number of complete rotations of the inner ring with respect to the outer ring; space sampling (in the ND acquisition board 9) the processed vibration signal (y(t)) based on the processed position signal (x(t)); and predicting a fault in the rolling bearing based on the space-sampled vibration signal (y(t)).
