We have an electronic "shipping" scale with sufficient capacity, but as we're also interested in finding our center of gravity, we purchased four fish weighing scales last year, and made four stands modified from those metal hooks used to deep-fry turkeys. Last year we went mecanum (totally underestimating the importance of defense), and wanted to balance the weight on each wheel. This year, we've got an H-drive, and we've built it so that we can move the strafe wheel forward or backwards in 1" increments, using the holes in the side rails of the KOP drive chassis. As we now plan to carry up to four totes at a time, then stack two more totes and and RC atop that, we'll probably try to optimize the strafe wheel location for carrying three totes. Knowing the weight at each corner will not only give us total weight, but also COG.
