Robots Track Moving Objects with Sub-Centimeter Accuracy

A system was developed that uses radio-frequency identification (RFID) tags to help robots target moving objects with unprecedented speed and accuracy. The system could enable greater collaboration and precision by robots working on packaging and assembly, and by swarms of drones carrying out search-and-rescue missions. Robots using the system can locate tagged objects within 7.5 milliseconds, on average, and with an error of less than a centimeter.
