1. A system for autonomously conveying and loading a shell into a fixed gun, the system comprising:
an autonomous conveyance device configured to autonomously travel and move according to an autonomous driving program from a shell storage location to a fixed gun fixed to a gun mount that is a destination;
an automatic loading device configured to hold a testing shell and automatically load the testing shell into a cartridge chamber of the fixed gun; and
a shell lifting device mounted on an upper surface of the autonomous conveyance device and a lower surface of the automatic loading device and configured to move the automatic loading device upward or downward,
wherein the automatic loading device comprises:
a tray on which the testing shell is seated; and
a rammer coupling member mounted on an upper surface of a rear end of the tray, and
wherein the automatic loading device further comprises a shell rammer device configured to load the testing shell, which is seated on the tray, into the cartridge chamber,
wherein the shell rammer device comprises:
a body having a rear end coupled to the rammer coupling member;
a rammer inserted into the body and having a front end disposed rearward of the testing shell; and
a rammer driving means configured to move the rammer forward or rearward wherein a loading position sensor is mounted at an upper end of a front end of the tray and detects a loading position of the testing shell made by a forward movement of the rammer.
