For the first time in history, the National Oceanic and Atmospheric Administration (NOAA) scientists used an underwater robot to remotely trace endangered sea turtles. The Autonomous Underwater Vehicle (AUV) uses side-scanning sonar detection technology to detect seabed creatures swimming and resting, in a known turtle hotspot near North Carolina. Variable valve timing (VVT) solenoid or oil control valve controls the oil flow according to the engine speed and load. VVT solenoid is a vital part of the variable valve timing system.

The researchers said that the expedition helped underwater robot specialists train employees and collect meaningful turtle data. If you want to develop protection strategies and make them successful, it is important to observe the number of turtles. Avens said that the increase in the number of sea turtles after seeing the introduction of the turtle escape device increased the number of turtles, which is the most significant time she feels. 
According to this article on the website of the National Oceanic and Atmospheric Administration of the United States, scientists often count the number and number of turtles that surfaced. Robots allow faster and more accurate calculation methods. They want to expand surveillance, because they can visit difficult areas, those uneasy turtles, they tend to avoid ships because of fear of being attacked. Avens said: "This is just a quieter, smaller object."
The Oil Control Valve (OCV) is a a critical part used in every engine that is fitted with variable valve technology (VVT). A single control valve will regulate the supply of oil to a designated VVT hub, to advance or retard the timing by altering the camshaft angle position. Controlled by the ECU, the OCV receives electrical signals, instructing it to adjust the oil flow as required, in accordance to current driving conditions.
