As the current generation of commercial telemetry devices do not meet the computational requirements of such algorithms, a new compact signal-processing module has been developed. The key feature for this unit is that it is able to provide data processing rates of at least 80 Mflops (million floating-point operations per second) while being sufficiently compact for hand deployment and having low quiescent power consumption for long-term deployment. This paper presents details of the modem hardware and software architecture together with preliminary results from the first deployment using the new system.","PeriodicalId":231222,"journal":{"name":"Proceedings of IEEE Symposium on Autonomous Underwater Vehicle Technology (AUV'94)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116865974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensory systems and behaviors exhibited by these animals are well adapted for robust operations in turbulent and chemically complex environments. The algorithms used by an animal to rapidly extract guidance information from a discontinuous and complex chemical signal are presently unknown and are the topic of current research. We have developed a small benthic robot that is being used as an algorithm test bed for ideas in biological chemosensing behavior. The robot is designed to mimic the basic features of a lobster relevant to chemical sensing and associated behaviors.

Research has shown that mammalian sonars are superior to any man-made sonars in such environments. This paper describes a novel signal processing concept based on recently discovered echo processing operations used by echolocating bats and dolphins. The signal processor uses unique front-end filters followed by nonlinear functions emulating auditory neural models to effect high resolution at low frequency. Processing emulations confirm performance far superior to conventional processing techniques. Of particular importance is the system implementation using a scalable architecture that can be integrated into an AUV to suit various missions. Results of simulation and data analysis are included here which demonstrate the processing gains realizable by the proposed technique.","PeriodicalId":231222,"journal":{"name":"Proceedings of IEEE Symposium on Autonomous Underwater Vehicle Technology (AUV'94)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114886963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The solids managed aluminum fuel cell power source will exceed the ARPA defined requirements in terms of energy and power density if liquid oxygen is used as the oxidant supply. For higher power density applications, the solids free aluminum fuel cell power source can provide 60 kWh at 3 kW from a 4-foot long section of a 21-inch diameter vehicle. Higher power density and energy density versions of both the solids managed and solids free aluminum fuel cell power source requires the development of open cycle systems.

The areas of transponder-based navigation are defined by the maximum range of transponder operation. In both modes, a Kalman based design approach was chosen, using, when necessary, the available position estimates to characterize the errors associated with the filter inputs.

In this paper, a quick adaptation method of the controller, called imaginary training (IT), is proposed to improve the time-consuming adaptation process of the original SONCS. IT can be realized by a new parallel structure which enables the SONCS to adjust the controller network independently of the actual operation of the controlled object. In the proposed structure, the SONCS is divided into two separate parts: the real-world part, where the controlled object is operated according to the objective of the controller, and the imaginary world part, where the IT is carried out. A forward model network which can generate the simulated state variables without measuring actual data is introduced. A neural network, called \"Identification Network\", which has a specific structure for simulation of dynamical systems is proposed as the forward model network in the imaginary-world part. The effectiveness of the IT is demonstrated by applying it to the heading control of an AUV called \"The Twin-Burger\".","PeriodicalId":231222,"journal":{"name":"Proceedings of IEEE Symposium on Autonomous Underwater Vehicle Technology (AUV'94)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133694983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cooperating AUVs must also be able to exchange information and request help from their collaborators.

In addition, the AUVs which receive these messages must be able to interpret them in the context of their own information about the world.

Among the RBM's strategic, tactical, and execution levels, the tactical level performs a role to bridge the strategic and execution levels. That is, it provides behaviors to the strategic level and controls the execution level based on the commands (behavior activations) from the strategic level. To meet these requirements while maintaining non-interrupted vehicle operation, the tactical level has to be able to handle the concurrently operating behaviors. This paper describes a concurrent, object-oriented implementation for the tactical level of the NPS autonomous underwater vehicle with use of the Ada task construct. This paper also presents evaluation scenarios and results obtained from the NPS AUV high fidelity dynamic simulator.","PeriodicalId":231222,"journal":{"name":"Proceedings of IEEE Symposium on Autonomous Underwater Vehicle Technology (AUV'94)","volume":"376 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131842230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
