1. A tubular handling system for conducting a subterranean operation, the system comprising:
a bridge disposed in a horizontal position proximate a drill floor, the bridge comprising first and second bridge rails with a space between;
an arm coupled to the first and second bridge rails, the arm configured to manipulate a tubular through the space between the first and second bridge rails, and to move along the bridge; and
a tubular lift system that raises or lowers the tubular in a horizontal orientation between a horizontal storage area and an intermediate storage location, the arm being configured to collect the tubular from the intermediate storage location and present the tubular to a well center on the drill floor or to a pipe handler, or to collect the tubular from the well center or the pipe handler and deposit the tubular in the intermediate storage location.
