1. A surgical cutting and fastening instrument comprising:
an end effector, comprising:
a first jaw;
a second jaw movable relative to the first jaw; and
a staple cartridge comprising a plurality of staples;
a shaft operably coupled to a robotic system and said end effector, the shaft comprising at least a portion of a drive train for actuating the end effector;
an electric motor to actuate the drive train;
a power pack that comprises at least one charge-accumulating device connected to the electric motor for powering the electric motor;
a plurality of sensors positioned within the end effector to measure impedance; and
a control circuit to:
actuate the electric motor to deploy staples from the staple cartridge during a firing stroke;
monitor the impedance at a first location along a length of the firing stroke; and
monitor the impedance at a second location along the length of the firing stroke, wherein the first location and the second location are different.
