Meet the Guardian LF1 Undersea Robot: an unmanned robot designed to control the population of invasive lionfish in the Atlantic. The robot is designed to depths down to 400 feet. It consists of a remotely operated vehicle tethered to a remote surface control station. Its controller lets you locate and capture lionfish.
The ROV has 8 thrusters mounted on it to move smoothly under water. A single unit can capture 10 lionfish before returning to the surface.
