Meet Jellyfishbot, the robot that eats trash on the sea

The Jellyfishbot flickered a yellow glow amongst white boats docked at a southern French port, as the robotic sea-cleaning boat gobbled up plastic bags, discarded drinks bottles, and even used surgical masks floating on the water. At the port of the French city of Cassis, the remote-controlled electric powered boat weaves around the harbour sucking the trash into a net that it trails behind its hulls.
