For their senior capstone project, Northeastern electrical engineering students Cameron Olean, Ben Leathe, Tim Hickson, Chase Hathaway, Dan Petrillo, and Andrew Barada, developed TRAQ—an autonomous quadcopter that uses a unique four-element antenna array to locate and navigate to the source of a radio signal. The quadcopter’s potential applications include disaster relief, surveillance, search-and-rescue, and stolen goods recovery. The quadcopter’s autonomous nature also enables multiple crafts to coordinate their movements and provide greater location accuracy. The team developed TRAQ under the guidance of faculty adviser Bahram Shafai.
