Robot Guide Dog Leads the Blind

The Swirling Brain sent a link to a recent Utah State University story on the development of a robot guide dog. The robots are based on the Pioneer 2DX base and include SICK laser sensors, sonar, differential GPS, and sonar. A laptop computer acts as the robot's brain. One of the more interesting features is the use of RFID tags that can be placed in the environment to help the robot localize specific objects. The user selects a location from a braille directory and the robot guides them to the associated RFID tag. For a more detailed description of the robot guide dog, see the recently released research paper, RFID in Robot-Assisted Indoor Navigation for the Visually Impaired (PDF format). Several video clips of the robot doing its thing can be found on the website of Chaitanya P. Gharpure at Utah State.
