By day, it is a lowly vacuum, its shell a cheery red, sucking up dirt and unwanted filth. By night, in the darkness that is, it is the Roomba of Doom, a cold-hearted black, low-slung, sleek machine of doom, sucking up dirt and zapping unwanted filth (sp: intruders).
Because Roombas wander around the house when vacuuming, have them store the layout of permanent objects in a matrix data set, and add one of those battery-powered shock-prod defense tasers. Then, at night, have it seek out movement found via IR cameras, placed around the house, that track anybody who breaks in.-- DesertFox, Apr 01 2006 Deer Aibo DeerAibo [theircompetitor, Apr 01 2006] Or anyone getting a midnight snack in direct contravention of doctor's recommendations.-- methinksnot, Apr 01 2006 good thing cats can run faster than the roomba. What happens of you have to visit the mens room during the night?-- jhomrighaus, Apr 01 2006 It doesn't track you, it tracks bodies entering the house via IR cameras. The cameras are connected to a computer and track the illegal body through 3D space, and wont mistake you for somebody else, unless you run up and hug them.
Or you could enter a temporary shut-off code into one of the security panels.-- DesertFox, Apr 01 2006 Can it have a shark fin on top, and a speaker that plays 'Jaws?'-- RayfordSteele, Apr 01 2006 If you want it to.-- DesertFox, Apr 01 2006 [jhomrighaus] You have a men's room in your house? ... thinks ... Is that the one with the dart board in it?-- squeak, Apr 04 2006 random, halfbakery
