Recently, this blog reported on the ongoing investigation into the Antikythera shipwreck site in Greece, which has required such novel equipment as an innovative "exosuit." In addition, scientists have been using the Sirius robot for surveys.

According to the Maritime Executive, the Australian-made Sirius is technically an Autonomous Underwater Vehicle or AUV instead of an ROV, but functions in a similar way, patrolling underwater for information. The main difference is that this type is able to maneuver without cables connecting it back to a launch craft.

The different capabilities of the device have allowed it to do lots of work at the wreck area, such as sonar and visual surveys. Other features of the AUV include a sensor that allows it to detect pitch and roll along with the motions of the waves.

Video included with the source shows the Sirius moving steadily underwater on its rounds. The site is famous for its treasure trove of ancient art and technology, including the Antikythera Mechanism, thought to be one of the earliest "computers."  Before 2012, the wreck had been ignored by explorers and scientists for more than 30 years.

The AUV unit was based on a model utilized by the Massachusetts-based Woods Hole Oceanographic Institute, which is also where the archeologist on the team that tested the exosuit, Brendan Foley, works normally. The dives will take the researchers as far as 1,000 under the surface.

Though there are key differences between them, AUV and ROV insurance are equally important for research expeditions because they pertain to the specific functions being used. When working with sophisticated equipment, knowing which features will be engaged the most is key.
