[Travis Hoffman]

Since your dumper is confined to quarters snug as a bug in a rug within the very safe confines of your robot's bumper perimeter, consider, all ye gravity fed dumpers, the minimum horizontal distance the balls must travel to find their way into the trailer promised land - the width of your robot bumper, the width of the trailer bumper, and whatever distance lies between the trailer base's edge and its vertical poles. Perhaps a chasm too great to traverse without additional aid....or perhaps not, with certain frame modifications. Either way, something to keep in mind as you design.
