1. An automatic guided vehicle (AGV) having the capacity to move product in a safe manner from a point “A” to a point “B,” the AGV comprising:
a chassis formed by a metal structure, a base plate, and a reinforced base at a front end of the metal structure, wherein the chassis further comprises a compartment at the front end of the base plate for coupling a tower, a counterweight at a rear part of the base plate, and a battery box facing the counterweight;
a protective casing comprising:
two side doors for accessing a-power board and a control board, respectively; and
two side hatches for introducing or withdrawing the battery box; and
two flanking covers covering three quarters of a length of the chassis of the AGV;
two sets of fixed wheels located at each end of the reinforced base;
two freely moving wheels attached to two support plates at rear ends of the metal structure;
a system of lifting mounted to the front of the metal structure, wherein the system of lifting comprises: a support mast, a lifting carriage, a lifting cylinder, a raising carriage, a fork hanger frame, and two front forks, wherein: the lift truck vehicle has a driving and steering wheel coupled to an electric motor, wherein the driving and steering wheel is positioned between the two freely moving wheels to displace and steer the AGV;
a navigation and safety system comprising:
security laser scanners attached to angled frames at the rear end of the metal structure;
a navigation sensor upon an upper end of the tower to determine a position, an orientation, and a speed of the AGV;
a proximity sensor upon a front part of the chassis to detect possible objects in front of the lift truck; and
at least two angular positioning sensors upon the front part of the chassis for measuring changes in angular and linear position with respect to a reference position when a given load is being lifted; and
a connector used for connecting a manual remote control to control the AGV in a manual mode.
