The use of marine space is important for countries and researchers, since half of the ocean floor beyond 3000 m of depth, the discovery of this environment is not easy, Having a look and interacting is a challenge for a human supervisor [1]. The information in this environment is inaccessible by humans, There are several types of underwater robot who repents that need.[2] The design of such a machine is essentially based on the type of mission to be performed. The sea trials were conducted at depths of 3000 m in 2010, 5000 m in 2011, and, finally, 7000 m in June 2012 [3].
