Flies and moths are naturally attracted to light. The Lampshade Robot has holes based on the form of the pitcher plant enabling access for the insects but no escape. Eventually they expire and fall into the microbial fuel cell underneath. This generates the electricity to power a series of LEDs located at the bottom of the shade. These are activated when the house lights are turned off.
More Carnivorous Domestic Robots, by Auger-Loizeau and Alex Zivanovic, this way!
The Carnivorous robots are currently on view at LABoral in Gijon (SP) as part of the exhibition Nowhere/Now/Here.
