The lionfish zapper hits the open seas

This 3D rendering of a lionfish harvester robot was developed by Robotics in Service of the Environment (RISE). The prototype uses a robot arm with two metal electrodes on the end to electrocute invasive lionfish, which are then collected in a central chamber for use as food. The America's Cup sailing race kicked off this week in Bermuda, but a month ago, a different type of competition was held in the island's lucid waters. It was a contest that pitted chef against chef and robot against beast. Last August, NewsHour broke the story of a robot being developed to stop lionfish, an invasive species that has decimated Atlantic coral reef ecosystems due to their insatiable appetites for other fish.
