Call it the son of submarine. In 2012, the first OpenROV tethered unmanned underwater robot, also crowdfunded on Kickstarter, combined the utility of a cheap submarine with the form factor of an off-brand iMac. For their return to crowdfunding, OpenROV's Trident packages several improvements in a slick, white-and-black body. With under two days left before the project closes, they've already raised over $760,000 of their initial $50,000 goal.
Want to see what it looks like when you get chomped on by a great white shark? Of course you do. This video, made by the Woods Hole Oceanographic Institute, shows great white sharks near Guadalupe Island, Mexico. In 2013, Woods Hole researchers equipped a Remote Environmental Monitoring Unit, A.K.A. a REMUS-100 robot, with five cameras to find sharks and tag them. When the researchers sent REMUS underwater in Mexico, they got an eyeful of the sharks' territorial and predatory behaviors. The sharks snuck up under the robot in much the same way they stalk and nab seals, the video explains.
