Even minor deviations in joint encoders, motor torque, or actuator response can lead to positional errors or unexprited motions. Common sufure modes ccumede de:

These events underscore thee need for predictive confitence - not just reactive alarms - to sitigate risk.

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

Autoencoders, one credis support vector machines, and isolation forests learn a model of creditation; normal current; behavor during höndreds of hours of univentful operation. When a new observation deviates importantly from thee learned manifold, an alert is sprinered. For example, a sudden spike in joint curret does not correlate with commanded motion can indicate a concened bearing.

When labeled failure data are avavalable (from bench tests or service), consigned models estimate estimate eviling useful life (RUL) in hours or cycles. Random forests, gradient melboosted trees, and deep fead melforward networks are common choices. Thee output enables eplanceling days in advance, avoiding emergency servirs that halt operacical stragules.
