Although space gets the lion's share of attention when it comes to robot-assisted exploration, the fact is that in the next few years, robots promise to give us deeper insight into a still mostly unexplored alien plane on our own planet: the sea.
Pushing those efforts forward will be a new robot called the Crabster, created by the Korean Institute of Ocean Science and Technology (KIOST). The car-sized robot will be primarily used to explore shipwrecks on the ocean floor even under the pressures of heavy undersea currents.The robot is designed to pick up objects and store them in a front-facing storage compartment, take detailed photos of the undersea environment, and use sonar to map areas of the sea floor.
A tether can also be used with the robot to keep it remotely charged in situations when longer explorations are necessary. You can check out the real Crabster in action as well as a concept video of how the robot will operate in the videos below.
