A new underwater drone concept could seek and destroy one of the ocean’s most insidious enemies, while earning a profit for plastics recyclers. This marine drone can siphon plastic garbage, swallowing bits of trash in a gaping maw rivaling that of a whale shark.
Two pairs of self-propelled oceangoing robots have begun slowly making their way across the Pacific Ocean, setting off Nov. 17 from San Francisco on an epic journey covering 33,000 nautical miles. During their 300-day trip, the robots will collect 2.25 million pieces of data, and attempt to break a world record for the longest distance ever traversed by an unmanned vehicle.
Liquid Robotics, which built the gliders, aims to share all this data with scientists and the public. Through the Oceans portal in Google Earth, you can even follow the expedition online.
A new underwater robot designed to chase marine organisms and record their life stories combines the best attributes of long-distance gliders and short-trip propeller vehicles. Its creator says its range and science capabilities could completely change oceanography.
First dolphins caught on. Now underwater robots are using iPads to communicate, thanks to a new system designed at York University in Toronto.
As Technology Reviewreports, divers can use symbols on tablet computers to control underwater 'bots. The system could enable enhanced diver/robot collaboration.
A team of unmanned subs developed by European researchers could use new software to work together as a team, exploring the ocean's deepest secrets, conducting search-and-rescue operations or, conceivably, sealing off a blown-out oil well.
The European Union-funded Grex project, named for the Latin word for "flock," involves networking software to coordinate multiple autonomous underwater vehicles, or AUVs. Multiple AUVs can benefit from the sum of their parts, as the project's Web site notes -- each could perform separate functions that contribute to a larger mission.
Already, smart unmanned subs are set to replace dolphins as undersea mine sniffers. Next tech: mine detonation, remote sleuthing and robotic combat.

Sheathed in a chilling veil of
rain, under cover of darkness, a few Navy Seals descend from a ship into a small rubber boat. They motor to a nearby harbor, idle the engine, and gently lower three torpedo-shaped objects into the water. The mission? Locate that persistent nemesis of amphibious operations: undersea mines. But tonight, instead of the specially trained dolphins or human divers who would normally do this work, the Navy is relying on robots.
