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.
New ceramic pressure hull design for deep water applications
Machines for deep-water application require pressure vessels in order to accommodate various type of units or human in the vessel securing them against the deep-water high pressure. In order to keep the machine to move freely in the water or on the bottom, the weight in the water should be as light as possible, and the pressure vessel must be fabricated as light as possible, keeping the pressure resistance capability.
