Could drones get X-ray vision through Wi-Fi?

August 07, 2014

Researchers have developed mobile robots that can use Wi-Fi signals to effectively “see through” walls. It’s raising the possibility of flying drones using the technology to see inside buildings. Led by Yasamin Mostofi, a professor of electrical and computer engineering, the group at the University of California, Santa Barbara (UCSB) has shown how the radio signals sent and received by a pair of wheeled robots can provide information about what lies behind concrete walls even when the objects do not move. Depending on their properties, objects behind a wall will attenuate the radio signals. As the robots make multiple passes around on either side of a walled-off area, one robot measures signals broadcast by the other.To read this article in full or to leave a comment, please click here
