If you've got something heavier in your backyard than the typical compost and delphiniums, the iRobot PackBot line may be for you. Designed to locate and defuse heavy ordinance, land mines, etc, it comes with a game console-style controller which allows a human to manipulate its mandibles as to snip the red or blue wires as need be. If you genuinely need one of these things, your life is probably too exciting. [GT]
