British designers James Auger and Jimmy Loizeau have designed a variety of household robots that feed on innocent pests to generate power — and to last long after their human owners die. And, they look just like furniture.

Auger and Loizeau designed a fly-trapping lamp that can be lit by digesting the insects attracted to its light; a table designed to catch and digest rodents to power its trap door and LED display; a clock that feeds on insects for power; and an art piece designed to attract spiders and recycle their kills. All of the furniture is designed to hill household pests while blending in with one's existing decor. Picutred below is the "lampshade robot," which emulates the killing methods of the pitcher plant. Bugs are lured into its illuminated interior, then consumed for fuel that keeps the lamp lit.

Other designs include flypaper on a conveyor belt that powers a clock (above), and a coffee table that eats pests that land on its surface.

Not satisfied to just kill pests, Auger has a larger goal. He tells New Scientist:

Although, for now, the robots rely on mains power, Auger believes they could become truly self-sufficient. "If the system fails, the grid goes down and all humans die, these robots could go on living so long as the flies don't go with us."

That's right: Auger designed his robots to go on long after we go off the grid by continuing to feed on whatever flesh can power its fuel cell. That seems like an excellent plan.
