Google Funds A Starfish-Killing Robot To Save Australia's Great Barrier Reef (abc.net.au) 122

"It looks like a tiny yellow submarine, but this underwater drone is on a mission to kill," reports ABC. Specifically, to kill the starfish that are destroying coral on Australia's Great Barrier Reef. An anonymous reader quotes ABC: In a bid to eradicate the pest, Queensland researchers have developed world-first robots to administer a lethal injection to the starfish using new technology... Researcher Matt Dunbabin said the technology was 99.4 per cent accurate in delivering a toxic substance only harmful to the starfish.... Divers have played a big role in helping to combat the starfish, but Professor Dunbabin said the robot would take the efforts to the next level. "Divers currently control certain areas, but there are not enough divers to actually make a difference on the scale of the reef," he said. The drone can also monitor and gather huge amounts of data about coral bleaching, water quality and pollution.
"RangerBot will be designed to stay underwater almost three times longer than a human diver, gather vastly more data, map expansive underwater areas at scales not previously possible, and operate in all conditions and all times of the day or night," according to Researchers at the Queensland University of Technology.

The starfish-killing robots were partially funded by Google (through their Google.org Impact Challenge program to fund and support nonprofit innovators), reports The Drive. One study had found the reef's coral cover declined 50% between 1985 and 2012, "with nearly half of that drop resulting from the coral-destroying starfish species."

    world-first robots to administer a lethal injection

    I thought, Google employees were very much against this sort of thing [slashdot.org]. And Electronic Frontier Foundation disapproves too [slashdot.org].

    Or is it only bad, when American military works on it?

    Yeah, sure "fish aren't humans" — will the robot (particularly, the software) require much rework to begin killing, say, enemy divers?

  • I hope we see more robots like this, to weed out Africanized honeybees from native bees (a small but loud propellor might do the trick), the invasive albizia trees in Kauai, the brown tree snake in Guam, etc. Also for forest management across North America, by strategically clearing out some of the younger trees in order to keep wildfire temperatures low and give the older trees a better chance to survive.

      This species of starfish is native to the region. The predation cycle they function under has been long ongoing.

      This modern trend of primeval nature worship that is rising among people who primarily spend their lives in the cities utterly alienated from nature, believing that natural state of things is stable persistence rather than constant cycles of boom and bust is anti-evolutionary to levels that are beyond even creationism.

        Nice try but one of the pest's few natural predators, the giant triton (a species of snail), has been unsustainably harvested from coral reefs for their shells. Their population has not recovered. So some population control of the COTS is definitely warranted.

  • But instead of starfish and coral it's terrorists and borders.

    Would it not make more sense to catch them and make food from them?
    Worst case cat food or dog food?

    In some countries it is common to eat them: http://www.chinesestreetfood.c... [chinesestreetfood.com]

      This is Australia. The spines are poisonous. You outsiders never learn.

    • I once proposed that we leak the idea that smoking Paterson's Curse (https://en.wikipedia.org/wiki/Echium_plantagineum) could get you stoned. Then the hippies would take care of it. Maybe this will work with the Crown of Thorns starfish, if the hippies can hold their breaths long enough.

    • These aren't your friendly neighbourhood starfish. Crown-Of-Thorns are not edible. Even if they were, they are difficult to handle (being venomous like every other frigging thing in Australia)

      And if they were it wouldn't solve the problem either. There are many millions of the things. They are also very hard to indiscriminately catch. You can't fish for them, you need to dive for them.

      There are active efforts to kill them off en mass but even these efforts currently involve diving hitting them with a toxin

      • You can't fish for them, you need to dive for them.
        The robot injecting them could do that ... at least that was my idea.

        Nonetheless it is barely making a dent in the population.
        Obviously ... species like that simply release eggs and sperm into the water. As long as there is no one eating the eggs, killing them makes only more room for the offsprings.

        • killing them makes only more room for the offsprings.

          It's not a room issue. The problem is they will reproduce to the point of starvation and starvation will only occur when the entire reef is dead. They produce 50 million eggs per season each, only a small portion of them need to survive for that to be a problem.

          In peak season divers can kill about 45000 of these things each week. Even if all those were captured I doubt you'll find enough people willing to eat the things.

          • Well,

            if they are dead and are lying around on the ground, they are food for their offsprings.

            • Sadly no. These starfish don't feed on fish or each other. They feed on scleractinian which are the structures that support corals.

              They are an invasive pest for this reason, few natural predators and few natural sources for population control to bring them back to a level where they don't completely destroy the environment. :-(

  • It's about time they did something about those fucking starfish. I never knew there was a problem.
  • Next up (I hope), mosquitoes.

    Please click all the pictures with starfish on them until there are none left and then click OK.

    • I heard that Elon Musk talked to one of the lead researchers on the Crown of Thorns starfish and he's got his crack team of engineers designing a mini-sub to catch the starfish and bring them out to another place. Any day now they'll ship the sub to Australia and the problem will be solved!
  • with starfish and ends with humanity!
