Massachusetts Institute of Technology (MIT) researchers are using radio-frequency identification (RFID) tags to help track moving objects with unprecedented accuracy and speed.

The researchers demonstrated that the tags enable robots to pinpoint tagged objects within an average 7.5 milliseconds, with an error of less than one centimeter.

RFID tags can be applied to any object with the TurboTrack system. The system's reader wirelessly broadcasts a wireless signal that reflects off the tag and other nearby objects, and rebounds to the reader.

An algorithm mines the reflected signals to find the tag's response, and final computations leverage the tag's movement to enhance localization accuracy.

Said MIT's Fadel Adib, "If you use RF signals for tasks typically done using computer vision, not only do you enable robots to do human things, but you can also enable them to do superhuman things."
