For many of us, the space outside Earth is considered as the final frontier and we are always curious about things presenting in space. For marine researchers, the oceans also have as many secrets as in space. According to National Undersea Research Center in the United States, more than half of creatures on Earth are living in the ocean because 70% of the Earth\'s surface is made up of oceans. Therefore, it is no doubt that people always discover new creatures in the sea. With the desire to explore the most mysterious areas and deepest points in the oceans, scientists and engineers have invented many special vehicles that can travel and dive to deep parts of the oceans and bring back new scientific information.
A robotic sub named Nereus is currently the deepest-diving vehicle in service when it reached the deepest-known part of the ocean, the Challenger Deep in the Marianas Trench in the western Pacific Ocean.
Nereus can dive to 10,902m. With a robot like Nereus, we can now explore virtually anywhere in the ocean
NASA’s researchers have created its new robot named “Solo Trec”. It is a cool undersea robot which requires no battery change. The robot has been under use since 2009, diving to depths of 500 meters.
It can dive under unpredictable weather and climatic conditions.
Created by the Swiss designers from Rinspeed, the sQuba car is currently the first underwater car in the world. The car can dive at the depth of up to 30 feet below the surface of the wave.
Hunley was a submarine of the Confederate States Navy. It has been a local legend for 130 years. The ship was built at Mobile, Alabama, launched in July 1863.
It was sunk in a combat against an enemy ship. Its wreck was discovered in 1995 and was raised during the summer of 2010.
The Nymph was developed by Hawkes Ocean Technology in the U.S. It is an underwater vehicle that requires people at least a basic scuba qualification to use it.
DEPTH X has been developed by NASA. It can go over 300 feet in the ocean. In 2007, the vehicle illuminated the underwater walls of La Pilita, the second deepest sinkhole in the Zacatón system in central Mexico.
