During brainstorming someone suggested a goalie bot four feet long (possibly with a 20" extension that pops out at each end) by eight inches wide, 60" tall, and a drive system allowing it to speedily move sideways. Along the top would be a line of pneumatic pop-up blockers, which the operator controls with something like a piano keyboard.
Of course, this would completely block one driver's view if it wasn't made see-through. This led to speculation about an anti-goalie bot whose main strategy would be to block the opponents view, and whether such a monstrosity would violate gracious professionalism.
