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.
Design of an inexpensive waterproof housing
Last year, Lake Superior State University's engineering department started a program in undergraduate research and began the task of developing a remotely operated underwater vehicle (ROV). As the students researched the different technologies available for use they became aware that very little information was available for the design of underwater housings with through-hole connectors and motor shafts. Furthermore, commercially available housings were well beyond their budget. Because of this, they set out to design a low cost housing that could be manufactured either by them or by a local business. The goal was to develop 18" aluminum housings with endcaps for under $200. Multiple housings could then be connected to create an ROV. The housings would be designed for up to 300-foot depths. The endcaps would allow for either through-hole connectors or a motor shaft depending on the application. At this time the students have designed, built and tested the housing design and are well on their way to complete the ROV. It is believed that this information would be useful for a wide variety of audiences including any educational group interested in the development of their own ROV. This paper discusses the technical aspects of the design process and provides for development of a low-cost housing. A complete schematic and bill of materials are presented.
A Review of Pressure-Tolerant Electronics (PTE)
Abstract : Pressure-tolerant electronics (PTE) are those electrical or electronics components or equipments which are capable of proper operation in a pressurized environment. The environment may be gaseous or liquid. This review is intended to summarize the efforts which have been given to PTE in the past 20 years. Organizations presently active in PTE are listed. Some ideas are presented which may be used to develop candidate PTE of the future.
