Abstract: A method of operating a robotically controlled surgical instrument that includes an end effector, a driving assembly, and a lockout, the method includes inhibiting actuation of the driving assembly when the lockout is in a locked configuration in response to an unspent staple cartridge being absent from a first jaw of the end effector. The method also includes inserting the unspent staple cartridge into the first jaw of the end effector to switch the lockout to an unlocked configuration. The method also includes actuating the driving assembly to pivot the first jaw, which includes the staple cartridge, toward a second jaw of the end effector to at least one of staple or cut tissue with the end effector when the lockout is in the unlocked configuration.

Abstract: An improved amphibious all terrain vehicle having a subtantially rectangular body or shell and is constructed of a light-weight durable metallic material. A combustion gas engine is coupled to a dual hydraulic pump system which is centrally mounted within the length direction of the cavity for easy access and removal for repairs. An oil tank serves also as a seat base and is disposed within a central portion of the shell. Six-independent wheel motors are symmetrically disposed in series, three on each side of the shell and are plumbed in series for ground based mobility respectively. The wheels coordinate with a propeller disposed in the rear for amphibious propulsion. A fan is mounted on the under side of a front hood, near a dual lever, and switch controls for respective propulsion systems, and night-lights mounted on the hood respectively.
