Systems and methods for an Automated Guided Vehicle (AGV) capable of automatically balancing large and heavy objects for transport through a facility. One embodiment is an Automated Guided Vehicle (AGV) including a balancing plate configured to support a load, load sensors configured to detect a weight distribution of the load, and an actuator configured to shift the balancing plate laterally. The AGV also includes a weight balancing controller configured to determine a center of gravity of the load based on the weight distribution detected by the load sensors, to determine that the center of gravity of the load is vertically misaligned with a center of gravity of the AGV, and to direct the actuator to shift the balancing plate laterally to move the center of gravity of the load toward vertical alignment with the center of gravity of the AGV.

Weigh-in-motion sensors comprise a beam including a plate with a load-bearing surface, and a tube portion including a base wall and a cover and defining a cavity therebetween. A sensing package is disposed within the cavity and is under pre-load with the cover and the base wall. The sensing package comprises a piezoelectric element. The base wall includes an aperture extending from a mounting surface to the cavity. The aperture includes a fastener therein to secure the sensing package within the cavity. The fastener is sized having a cross-section dimension taken through a center axis of the fastener that is greater than that of a cross-section dimension of the piezoelectric element taken along the fastener center axis. In an example, the fastener has a cross-section dimension sized about 10 percent or greater in dimension than that of the respective cross-section dimension of the piezoelectric element.

Embodiments of the present invention are directed to a new and improved system and method for determining a weight rating for a surface road transporter by using a computing system and digital camera to identify various attributes of the transporter and then, based on those attributes, to determine a maximum allowable load limit for that transporter in a given jurisdiction. In addition, embodiments of the present invention may include a digital optical device and related software configured to scan and decipher a QR code printed on an “overweight” permit issued by a local jurisdiction, where the overweight permit authorizes a specific transporter to carry a load that exceeds its normal gross allowable weight by a specified amount or percentage. Embodiments of the present invention may incorporate the specified overage amount or percentage in its determination of the gross allowable weight rating for that transporter.
