An underwater robot that kills starfish to save corals,
What you see in the picture is an undersea robot whose details we know at spectrum.ieee.org can detect starfish and kill them with poison to save coral protected surfaces.
The problem to be solved is the invasion of the starfish crown of thorns, large, able to eat coral at high speed. In some cases they were detected over 100,000 of these stars in one square kilometer, a plague that now has a robot as an enemy.
Apparently the main cause of this invasion of stars is related to human activity on coastal land, agriculture, mainly water that carries nutrients attracting the attention of these animals.
Since a single large female can lay more than 50 million eggs, the problem is really serious.The classic way to combat this plague is the injection of venom by human divers, but only in that way can kill a starfish 120 per hour. Now it has developed a more effective, can kill within 24 hours after a single injection, poison being applied using the robot in the image above poison.
It is COTSBot (Crown-of-Thorns Starfish robot), torpedo-shaped yellow and 30 kilograms, capable of traveling at more than 2 meters per second and has a range of more than 6 hours. With an image recognition system it is able to detect the stars, using a learning system to achieve a detection performance of over 99%.
