A team of engineers developed a new search algorithm that allows robots to use RFID-technology to improve the robot’s ability to find objects labeled with self-adhesive RFID tags. The algorithm was tested using a modified PR2 robot equipped with directional antennas. The antennas allow the robot to receive stronger signals from a tagged object when they are close to it, similar to the childhood game “Hotter/Colder.”
The technology was tested using common household objects, like medication bottles, television remotes, phones, and a hair brush. The use of future home robots would be ideal for helping individuals with medication by identifying the correct medication through the unique RFID tag and delivering it to a specific person.
