Abstract:
1. A method for loading a transport having sides and a threshold with an automatic guided vehicle (AGV) comprising: engaging a load with the AGV; guiding the AGV with an inertial guidance system to a first position near the threshold of the transport; sensing more than one location of at least one of the sides of the transport using a secondary guidance system; guiding the AGV past the threshold of the transport using said inertial guidance system after said step of sensing more than one location of at least one of the sides of the transport using a secondary guidance system; guiding the AGV within the transport wherein said secondary guidance system uses said locations of said at least one of the sides of the transport to update said inertial guidance system as said inertial guidance system guides the AGV to an intended load position; depositing said load onto the transport at said intended load position; and guiding the AGV with said inertial guidance system from said intended load position to a second position, after said step of depositing said load onto the transport at said intended load position.
