German manufacturing company Vorwerk has partnered with Infineon in Munich to develop an electronic carpet that wirelessly navigates a robotic vacuum over every square inch of a floor. The special carpet has an embedded grid of RFID chips. Using an RFID grid for navigation is a novel use of the technology with many potential applications beyond carpet sweeping. Link
