The city of Rotterdam in the Netherlands has just launched a new type of water drone that is capable of autonomously patrolling the city’s port and cleaning up waste and debris as it goes.

Rotterdam is one of the most important port locations in Europe, situated at the mouth of several of the continent’s largest rivers. The most important of these is the Rhein, which allows ships to transport cargo to and from some of the most industrialized regions of Europe. Because of the enormous volume of ships moving through Rotterdam, the city’s port is having a difficult time dealing with waterborne waste, which is where its new “Waste Shark” drone comes in.
