The application of ROV (remotely operated vehicle) of the microcontroller submarine as a tool to take sample of water and soil contaminated by waste

This paper describes ROV (Remotely Operated Vehicle) that can take sample of contaminated water and soil while
the operator operates it on the shore or ship. User can operate ROV wirelessly. ROV is equipped with camera, robot hand,
GPS, accelerometer, compass, and other devices. The ROV is aimed to help researchers to research contaminated water and
soil that can be applied in and on the lake, river, and sea. The way it operates are syphoning water with mini pump and taking
soil sample with robot hand. The result shows that all hardware and software can run well underwater. So that, ROV in this
experiment can be used to take sample of contaminated water and soil in the place with maximum a depth of 1m. For the next
experiment, this ROV will be tested in other place with a depth more than 1m. however, this ROV will continue to be refined
to be maximally utilized.
