Scientists built an armed robot to protect coral reefs from invasive lionfish


Lionfish are incredibly eye-catching creatures, and they’re a favorite of salt water aquarium enthusiasts because they just plain look cool. They’re also an incredibly troublesome species when they are introduced in areas where they don’t belong, and coral reefs in the Caribbean are under serious threat from an invasion.

Now, researchers from the Worcester Polytechnic Institute have developed an autonomous robot that is capable of hunting down lionfish all on its own. But the bot doesn’t just identify and kill the invasive fish — using sharp spears to snag the fish and bring it down — it also allows for the dead fish to be fetched by fishermen who can harvest and sell it.
