The anti-crown-of-thorns starfish robot, or COTSbot, was developed by Matthew Dunbabin and Feras Dayoub of the Queensland University of Technology. Dunbabin, a robotics expert, said he had been thinking about the project for many years, but was held back by the available methods of eradicating the starfish. Previously, human divers needed to inject every tentacle of the starfish to kill it, he explained, but last year, James Cook University came up with a single shot injection system. “From a robotics perspective, it became a lot better for us. We could start to consider it a robotics problem.” The COTSbot comes equipped with a pneumatic injection arm that will deliver a fatal dose of bile salts to the crown-of-thorns starfish.
