The underwater robot, called SOLO-TREC, was developed in collaboration with NASA's Jet Propulsion Laboratory, US Navy, Scripps Research Institute and Teledyne-Webb Research.

Moving robots rely primarily on electricity generated by differences in sea water temperature at different depths.

In March, scientists completed the first experiment on the pressure of the SOLO-TREC robot during a three-month period in Hawaii.

So far, the robot has completed several tests at depths of 500m.

The power generated during the test process can basically meet the need for equipment that helps to operate the robot.
