Wow, that is an old picture!!
anwyay, the uberbots battery box consists of 4 thick plexi shelves supported by a frame of x-wing. It wasnt all that expensive to build, but it is heavy and the wheels were poorly constructed. Oh well, live and learn.
anyway, if you are looking for a neat solution, in 2006 pre-battery-box we simply used a plastic foldout workbench from home depot, and came up with a neat charging system to handle all of our batteries. all you really need is a clipboard with a sheet of paper attached to it and an organized student, and you have your 'battery box'
