Experimental study on pressure resistance performance of the plastic housing for the underwater robot system
The underwater housing is used to protect the electronic parts of the underwater robot system from water and pressure. The housing made of a metal material is widely used, but the weight is heavy and the price is expensive. So in recent years the housing of plastic material that is inexpensive and lightweight is being used in shallow water depth. In this paper, we have obtained the pressure resistance performance in several plastic housing specimens by the high pressure experiments. In the experiments result, we know the pressure resistance performance of the oil filled housing specimen better than other specimens.
Hybrid pressure-tolerant electronics
When working in deep-sea environments, the ambient pressure of the water column causes special design effort on the integration of electronic components for robotic structures. Until recently, electronic modules required housings which allowed the use of electronics at pressure conditions like they are on land. These housings increased the costs and the dimensions of the overall system as those modules are bulky and expensive to manufacture. Other ways have to be taken when designing miniaturized components. A hybrid approach between pressure tolerant systems design and pressure hulls enables the realization of miniaturized and cost-effective components for deep-sea.
Concept design of solar cell satellite dish
Solar panels are devices that consist of solar cells that convert light into electricity. They are called solar on the Sun or “sol” because the Sun is the strongest light source that can be utilized. Solar panels are often called photovoltaic cells, photovoltaic can be interpreted as “light-electricity”. Solar cells or PV cells depend on the photovoltaic effect to absorb the Sun’s energy and cause currents to flow between two opposing charged layers. The purpose of this study is to analyze the satellite dish using solar panels, so this tool is a signal search tool that uses solar energy to run to carry out its functions. As we know that many places or areas that are still often experiencing power outages so that it can hamper and interfere with community activities. Therefore, this research wants to facilitate the public, especially the current generation who need electricity every day so that when there is a power outage, the satellite dish will utilize solar energy as its main source. This research uses a satellite dish as an intermediary to produce electrical energy with the help of solar energy and is collected into a high-voltage battery in the form of electricity, so that it becomes a source of electricity.
