Texas A&M University's Center for Robot-Assisted Search and Rescue (CRASAR) are using a few different types of underwater robots to aid in Japan relief efforts. Starting in the Minami-sanriku coast on Aril 19th, the team is expanding the search throughout the Sendai area.
Regular human divers have a difficult, if not impossible, time navigating through murky waters. The bots being used have been fitted with special sonar sensors that allow them to move in the most extreme conditions. Sonar and video footage is returned via a tether, as well as control signals in the opposite direction. 3 bots are being used. The "Seamor" is a large suitcase sized bot, the AC-ROV is about the size of a shoe box, and the SeaBotix SARbot is somewhere in between. The SARbot is a battle hardened device used to often rescue people from trapped cars underwater.
Robotics and Engineering prowess are really being showcased in the midst of the Japan 2011 disaster. Just proving the world needs more engineers, more development, and more innovation to make everything easier, including crisis management. Exactly why Darpa wants to see more advancement in robotics.
CRASAR have also used robots in aid during WTC 911, Katrina, La Conchita Mudslide, and the Crandall Canyon mine collapse. See more at their site.
