Claim 18:
19. A robotic surgical system comprising:
(a) a robotic arm; and
(b) a surgical instrument configured to be removably coupled with the robotic arm, the surgical instrument comprising:
(i) a shaft assembly,
(ii) an end effector operatively coupled with the shaft assembly,
wherein the end effector comprises:
(A) a first jaw including an anvil, and
(B) a second jaw configured to removably receive an unspent staple cartridge, wherein at least on of the first or second jaws is configured to pivot relative to the other of the first or second jaws,

(iii) a firing system extending along a longitudinal axis through at least a portion of the shaft assembly and the end effector, wherein the firing assembly is operable to at least staple and cut tissue, and
(iv) a firing lockout assembly selectively coupled with the firing system, wherein the firing lockout assembly is disposed proximal to the end effector, wherein the firing lockout assembly is configured to:
(A) allow actuation of the firing system in an unlocked configuration in response to the unspent staple cartridge being coupled with the second jaw, and
(B) inhibit actuation of the firing system in a locked configuration in response to the unspent staple cartridge bring absent from the second jaw,
wherein the firing lock assembly includes a first engagement projection and a lockout,

wherein the lockout is configured to translate along the longitudinal axis between the unlocked configuration and the locked configuration,
wherein the lockout includes a first flexible deflectable portion disposed proximal to the end effector, and
wherein the first engagement projection is configured to inwardly bend the first flexible deflectable portion toward the longitudinal axis to inhibit actuation of the firing system in the locked configuration.
