We made ours with 1/16 wall 1" steel square tubing that was student welded. A set of EXTRA BEEFY mecanum wheels that make it a breeze to maneuver and some nice bearings that allow it to be pushed in any direction with one finger while having 400 lbs on its bed. It can have 12 batteries on board and nice tool set. It can handle a 4" high wire bump with ease. It has adjustable rails that the robots' dead axles sit on so we cant test the drive train and easily work from under the robot. It soon will be motorized and will use 4 AM Super Shifters that have a gear taken out of them so we can shift into neutral to make it really easy to push. It'll also have underglow and headlights for loading/unloading at night. But one of my favorite feature's is that with the removal of two pins that hold a rail on, you can flip up part of the middle tray and it becomes a comfy 2 person couch (it'd be really fun at demo's!) perfect for the practice field and when our drive team is exausted.
Still no pictures, but there coming.
