Abstract
The system for automating well construction operations includes a plurality of sensors, such as a fingerboard latch position sensor for providing position of a fingerboard latch, a stick-up height sensor for determining a height of a portion of a tubular section extending from a well center, a pipe handler rotation sensor for detecting a position of a pipe handler, a bell guide clearance sensor for measuring a distance between a bell guide and a tool joint, a link tilt position sensor for measuring an angle of a bail with respect to a top drive, an elevator latch status sensor for detecting whether an elevator latch is open or closed, and a power slips sensor for detecting whether a power slips is open or closed. Further, the system includes a controller in communication with the plurality of sensors and configured to command one or more equipment based on inputs from the sensors.
