Underwater Robots
Nowadays we use Remotely Operated Vehicles and Autonomous Underwater Vehicles to explore the ocean. ROV's are operated with a special cable while AUV's are operated without pilot. Underwater robots are able to navigate through the ocean and gather information to bring back to the scientists and allow them to gain knowledge about the ocean and what's under it. This is interesting because simple technology helps us view the ocean and help us discover new species.
