A drone killer would now provide coral babies on the Great Barrier Reef

The Great Barrier Reef has a new robotic alliance.

In September, RangerBot, developed by researchers at Queensland University of Technology (QUT), He began to tour the Great Barrier Reef, A deadly starfish hunt that causes coral names, in addition to mapping and tracking the health of a reef. Now, this deadly drone has been engineered not only to take life but also to deliver it.

Log in to LarvalBot, The robotic coral midwife of the Barrier Reef.

Collaboration between researchers at Queensland University of Technology (QUT) and South Cross University (SCU), To Rafael It is able to provide baby corals through the Great Barrier Reef as an "underwater pollen.

"It's like spreading fertilizer on your lawn," says Matthew Dunbabin, a professor at QUT and developer of the UAV technology. [the drone] Surfing along we target where larvae should be distributed to new colonies so that new coral form communities can develop. "

From October to December, parts of the Great Barrier Reef undergo a multi-coral coral-producing event in which many coral species release bundles of eggs and seed from their abdominal cavity into the water. The bundles float to the surface and fertilize, form coral larvae before settling on the ocean floor, and eventually develop into a colony.

During the spawning event, researchers at the SCU collected the kits and treated them, preparing them for dispersion using a drone.This process was accomplished by a team led by Professor Peter Harrison and involved researchers at the James Cook University of Technology at Sydney University .

Loading 100,000 larvae into LarvalBot, The researchers then used the wisdom of the buzz to locate specific sections of the reef that would benefit from the redistribution of the coral. After activating the buzz through the iPad, a researcher could then tell him to drop his cargo – hundreds of thousands of coral babies – onto the reef.

It's a bit like the version of the Great Barrier Reef of Hans Christian Andersen's storks.

Importantly, it was just the first sentence that malice killer technology could be reengineered and deployed for another purpose, so far it seems to have worked as planned. But this is not the end – in 2019, the team will look to catch and treat even more corals coral, using To Rafael To settle coral on damaged parts of the reef.

"With further refinement research, this technique has enormous potential to operate across large areas of reef sites in a way that was not previously possible," said Professor Harrison.

The Great Barrier Reef, a World Heritage Site, has undergone many coral-bleaching events and has suffered from climate change and pollution for decades. The buzzing technology is part of broader efforts using technology Such as artificial reefs, simulations and Updated mapping techniques To try to restore and protect the site.
