This is Zwischenräume, a mechanical art installation that features a bunch of autonomous robots hiding behind a living room and beating it down at random intervals, stopping only to peer at the gawkers outside.
Explains builders Petra Gemeinboeck & Rob Saunders, who go by the alias RoboCoco:
The installation embeds a group of autonomous robots into the walls of a gallery. They punch holes through the walls to inspect what's outside, signal each other, and conspire. As if the walls had ears and a hammer to pierce holes for their eyes to see. The work develops a political relationship between the stealthy invasion of digital surveillance and urban combat tactics in which soldiers are instructed to walk through private walls. The installation stages this relationship in the form of an autonomous sculptural process that marks and wounds our environment, leaving behind open scars.
It's not as shocking as ED-209 getting all Kool-Aid Man on your sitting room, but the notion of a robot slowly and methodically chipping away at your house is creepy in of itself.
