2. Underwater robots meet invasive species

On the off chance that you think disposing of obtrusive species ashore is a test, you haven't had a go at doing it in the profundities of the sea. Robots that can slither over the ocean bottom dispatching trespassers with toxic substances or electric stun are being explored as a potential instrument for fighting such species. The innovation is currently being tried to control crown-of-thistles starfish, which have crushed Great Barrier Reef corals as of late, and obtrusive lionfish, which are contending with local species in the Caribbean Sea.
