Sometimes you really have to wonder about researchers and scientists, do they not read books or watch TV & Film at all! Because if they did the idea of creating a robot that can get inside the cavity of wall and then when the time is right rip its way through into the building would never leave the drawing board.
Yet here we are looking at this concept idea of a robot that can do that, now that is really going to help me get to sleep tonight!
These are the details for the robot that hides in the wall;
A robotic installation by robococo (Petra Gemeinboeck & Rob Saunders) ZWISCHENRÄUME (Interstitial Spaces) explores the anatomical trauma of a machine-augmented environment by embedding autonomous robots into the architectural fabric of everyday life. Each machine agent is equipped with a motorised hammer, surveillance camera, and a microphone to interact and network with the other machines by re-sculpting its environment. The gantry robot has been developed in collaboration with Icy Labs Sydney.
