A swarm of autonomous robots that can swim across bodies of water to collect garbage might be the key to saving the oceans.
A few years ago, RanMarine Technology, a company from the Netherlands, has introduced WasteShark, an aquadrone that works like a smart vacuum cleaner (essentially, a Roomba for the seas) to gather wastes that end up in waterways before they accumulate into a great big patch in the middle of the Pacific Ocean.

Every year, about 1.4 billion pounds of trash end up in the ocean. Plastics, styrofoam, and other nonbiodegradable materials get dumped into the waters, eaten by fishes and birds or collect into what has become the Great Pacific Garbage Patch — a gyre of debris between California and Hawaii bigger than Alaska.
Trash in seas and oceans have become a huge problem, but the WasteShark might be able to help.
RanMarine said that its aquadrones are inspired by whale sharks, "nature's most efficient harvesters of marine biomass." The company claims that the vessels can collect up to 200 liters of waste before it needs to be emptied and swim across the water for 16 hours.
