Zusammenfassung:	Described is a system for determining the current state of a drill using downhole sensors. The system includes a sensor suite mounted on a drill string proximate a drill bit and a computer mounted on the drill string proximate the sensor suite. The computer includes a trained classifier and is operable for performing operations of receiving online sensor data from the sensor suite; and classifying the drill bit as being in one of a plurality of pre-trained drill states based on the online sensor data. A drill bit controller can then be used to modify the operation of the drill bit based on the drill state classification.
