HizookRobotics writes Georgia Tech researchers announced a new way robots can "sense" their surroundings through the use of small ultra-high frequency radio-frequency identification (UHF RFID) tags. Inexpensive self-adhesive tags can be stuck on objects, allowing an RFID-equipped robot to search a room for the correct tag's signal, even when the object is hidden out of sight. Once the tag is detected, the robot knows the object it's trying to find isn't far away. The researchers' methods, summarized over at IEEE: "The robot goes to the spot where it got the hottest signal from the tag it was looking for, zeroing in on it based on the signal strength that its shoulder antennas are picking up: if the right antenna is getting a stronger signal, the robot yaws right, and vice versa."
