Exploring unknown environments with ultrasound

Many underground liquid-filled environments are difficult to access for humans—think of deep underground oil wells or water distribution systems. Even with modern cutting-edge technologies, it is difficult to map these areas. The PHOENIX project developed a swarm of sensor nodes to explore these unknown environments. Ph.D. candidate Gönenç Berkol worked on ultrasound communication between these nodes, an ingenious way to map the distance and location without the use of GPS. Berkol will defend his thesis on February 24th at the department of Electrical Engineering. Read More
