After the recent streak of robotic failures that we've seen, it's refreshing to see yet another success story come our way. Just as it did in February, the two-meter wide DepthX (Deep Phreatic Thermal Explorer) robotic submarine successfully mapped out a massive sinkhole in Mexico, but this time was quite a bit more rewarding. The cavern that it ventured into was the El Zacatón Cenote, which is better known as the world's deepest water-filled sinkhole, and the machine was able to delve some 270-meters down to "create the first map of the giant cavity." The hole itself is large enough to "swallow New York's Chrysler Building," and while the endeavor was indeed a success, researchers are hoping to get it back down there in the near future to better analyze a mysterious slope that it wasn't quite able to probe. Godspeed, DepthX.

We've seen mechanical devices creep through the inside of intestines, huge mounds of dirt, and even through the San Francisco Bay, but now a British deep-diving remotely operated vehicle (ROV) is getting set to probe the depths of Antarctica. In hopes of uncovering more about the effects of glaciers on the ocean floor, as well as details about the living creatures that inhabit said areas, UK scientists are carting the machine aboard the RSS James Clark Ross as they head for the Marguerite Bay area on the west side of the Antarctic Peninsula. The robot, dubbed Isis, will spend time on its inaugural January mission combing the seabed and channeling live video and pictures back to its captains via the built-in cameras, lights, sonars for acoustic navigation / imaging, and two remotely-controlled manipulator arms. Once the bot gets dried off (and thawed out) from its arctic expedition, the next tour of duty is already lined up, as Isis will head off to the Portuguese coast to do a bit more sightseeing. Of course, if you're interested in taking the £4.5 million ($8.81 million) creature out for a mission you deem worthwhile, it should be available for deep-pocketed renters soon after.
