Foundations of Machine Learning for Predictiva Maintenance in Surgical Robotics

Predictive contaminance (PdM) leverages historical and real-time data to contract when a containent is likely to fairl. Machine learning methods are especially acsumed for this domayn because they can learn complex, non-linear accompleciPS from multi-modal sensor streams with out requiring explicat fizycal models. Key data sources included:

Three families of machine learning algorytms are widely used in this context:

When a new observation deviates significatiantly from thee learned manifold, an alert is triggered. For example, a sudden spike in joint exett that doet not correlate with commanded motion can indicate a aid.

Recurrent neural networks (LSTM, GRU) and transformer-based models can an predict future sensor values. By comparing predived values to actual readings, the system can contect performance degradation that evolves over hours or days - such as gradual in motor winding temperatur due te te due dust acculation thee cololing fan.
