Roboshark: Remus 100 “Sharkbot” Tails Great Whites Off Cape Cod
Woods Holeâ€™s scientists get up close and personal with the great white shark.
This sleek, seven-and-a-half-foot shark-stalking machine, built by the Woods Hole Oceanographic Institution and known to friends as the REMUS 100, is designed to tail sharks and other creatures as they swim through the murky waters around Cape Cod. Sophisticated software allows it to react to the animalsâ€™ movements, while GoPro cameras let it get paparazzi-quality shots. Offshore, sharks sometimes dive as deep as 3,000 feet, but so far the sharkbot hasnâ€™t followed them down. â€śWe donâ€™t know what theyâ€™re doing there,â€ť says Greg Skomal, a senior biologist at the Massachusetts Marine Fisheries. At some point, Skomal plans to send the â€™bot down after them to find out. â€śThat,â€ť he says, â€śwould be pretty cool.â€ť
1.Â Custom Software
The â€™botâ€™s programming lets it make navigational decisions when trailing a shark, while also recording data about the water around it: depth, salinity, temperature, and more.
Lets the â€™bot gets a fix on its own position, but doesnâ€™t work underwater, so the â€™bot has to come up for â€śairâ€ť to find out where it is.
3.Â GoPro Cameras
Provided by Discovery Channel and Big Wave Productions, these have allowed scientists to film the predatorsâ€™ private lives. Footage shot last summer will air during Discoveryâ€™s Shark Week, which begins August 4.
4.Â Acoustic Receiver
Picks up a signal from the sharkâ€™s tag after it is â€śpingedâ€ť by the transducer, telling the â€™bot where the shark is and where itâ€™s headed.
5. Acoustic Transducer
Sends out a sonic â€śpingâ€ť to a tag previously placed on the sharkâ€™s dorsal fin.
