Well over 2,000 PackBots have been sold worldwide--small potatoes, still, against better than 3 million for the Roomba.
There's also a smaller, lighter variation on the PackBot called the SUGV (small unmanned ground vehicle), which was developed in conjunction with the U.S. Army's emerging Future Combat Systems program--and which may well get an expanded role with the Army even as many pieces of FCS look vulnerable to cost-cutting in the Pentagon's proposed defense budget.
