iRobot, the company that makes cleaning robots Roomba and Scooba, have also designed robots that don't care how many Dorito crumbs are on your kitchen floor. No, the PackBot has more important things to worry about than how disgusting and unpresentable your apartment is. It's a bomb defusing robot, and if it doesn't do its job it's safe to say that whatever area it's in will be a hell of a lot messier than it was beforehand.
PackBot is getting an upgrade, with the new PackBot 510 coming in April. The 510 boasts a 30% speed increase over earlier models, twice the gripping strength, and the ability to lift and drag objects twice as heavy. It should make it even more effective at defusing bombs so humans don't have to, something even your lazy, filthy ass can get behind.
