A new robot is showing promise to control lionfish, an invasive species that is in the water of the Bahamas and spreading south. The Guardian can dive hundreds of feet below the surface and stun lionfish with electrodes, then suck them into a holding tank. As it happens, the lionfish is a big hit on restaurant menus. The Guardian was developed by renowned roboticist inventor Colin Angle, who also developed the Roomba. Angle launched the “Robots in Service of the Environment” nonprofit to support the project. With no natural predators and with potent venom, lionfish can reduce the fish population around a coral reef by as much as 79%.
