original title: awesome! Robots developed by Queensland University of technology help save the Great Barrier Reef

Australia's Great Barrier Reef, which stretches 2300 kilometers, is known as the world's largest tropical coral reef ecosystem. It has colorful and species rich marine organisms. As a famous tourist attraction in Australia, I believe many students have seen the following introduction:

enjoy the world heritage - the Great Barrier Reef, and start a wonderful journey in this beautiful and soul stirring place. Looking around, the endless Coral Garden surrounds you. The blue sea water is full of color and vitality. Here, nature shows people its infinite charm and will bring you a wonderful experience that will be unforgettable for a lifetime

however

in this vibrant world, there is an animal that is unique. Like the villains in the movies, they have incredible power and can't be killed. At the same time, their ferocious and ruthless faces have become nightmares for all coral reef residents

what are they? Spiny crown starfish

spiny crown starfish are spiny skinned animals that inhabit tropical coral reef areas from the Indian Ocean to the Western Pacific Ocean. They can be divided into one stress check and two stress checks in the Philippines, Taiwan, China, Indonesia, Australia and New Zealand. They are distributed along the coastline of Lanzhou and the United States. According to the different living areas, spiny crown starfish have a variety of body colors: purplish red, cyan, yellow green, blue black, pink blue, etc

many fishermen or divers still accidentally touch them, resulting in stabbing poisoning. Mild poisoning may cause pupil narrowing, increased snot and saliva, severe headache, poor breathing and fear of light; In severe cases, incontinence, severe spasm, and even respiratory paralysis may occur

terrible coral killer

in 1963, the spiny crown starfish proliferated in Australia's Great Barrier Reef, and one fifth of the area was eaten by them. The adult spiny crown starfish can devour about 2 square meters of coral a day, and the coral reefs patronized by spiny crown starfish will only have a piece of white coral skeleton

spiny crown starfish have strong vitality. Even if all their tentacles are removed, or most of their bodies are destroyed, or even cut to pieces, they will still not die; The broken pieces can still grow into all the spiny crown starfish in the future. Because of its remarkable vitality, spiny crown starfish is also called "devil starfish"

in the past few decades, the population of spiny crown starfish has increased exponentially in some coral reef islands, resulting in a large number of deaths of live corals, leaving only a dead, white boned coral reef. The surrounding waters of the albino coral group are like cemeteries, no longer full of vitality and bright colors. That is, the automatic uniform cooling and constant temperature of the sample will slowly restore the marine environment, but it will still take 10 years or more for the coral to recover

after two years of innovative research and development, the world's first Diving Robot rangerbot, developed by scientists of Queensland University of technology, made its first public appearance on August 31 this year. This robot will serve as the "coral reef protector" listed as the world heritage Great Barrier Reef and won the 2016 Google impact challenge people's Choice Award

rangerbot's total weight will soften 15kg at 74 ℃, with a length of about 75cm. It can cruise for 8 hours each time. It is equipped with TCBS gel injection needle, which contains lethal elements to spiny crown starfish. Once the big demon king spiny crown starfish is found, it can be injected, waiting for the bacteria to destroy it, without damaging or affecting other coral reef organisms

qut Professor Matthew dunbabin said that through the computer vision navigation function, rangerbot can monitor various problems that affect and threaten coral, including coral bleaching, seawater quality problems, invasion of harmful species, pollution and sludge accumulation

at present, the number of spiny crown starfish tends to be stable with high intensity due to human intervention, and the relevant prevention and control work is also running normally. The sea demon king has also lived a quiet life from nine to five
