Cigarette butts pose a huge risk to the world's oceans and can be a pain to clean up by hand especially on public spaces like beaches. A group of Italian scientists have built a quadruped robot that can identify litter and pick up the smaller bits with its leg mounted vacuums. VERO, the vacuum equipped quadruped robot, is a four-legged device designed to look for and clean up litter on a variety of terrains. VERO was designed and built by a team of researchers from the Dynamic Legged Systems lab at the Italian Institute of Technology in Genoa, according to USA Today. The group published a paper back in April on VERO's development and effectiveness in the Journal of Field Robotics. The research paper states that cigarette butts are a serious concern.
