This paper conveys some of the results of a research project involving the design and tests of biomimetic underwater vehicle which is intended for implementation of intelligence, surveillance and reconnaissance tasks. The research presented in this paper is based on the theoretical and practical study. All major subsystems of the robot are specified and briefly described. The mechanical design is based on modular structure. Two types of modules, dry and wet, are specified. The major parts of the tail module were checked with the use of the finite element method. Moreover, hardware and software parts of robot's control subsystem and Simulink model of static depth regulator are briefly presented. The final part presents main parameters and basic functionality of the built biomimetic underwater vehicle.
Abstract:The efficiency and sustainability of a cellular manufacturing system (CMS) in batch type manufacturing is highly valued. This is done using a systematic method of equipment into machine cells, and components into part families, based on the suitable similar criteria. The present work discusses the cell formation problem, with the objective of minimizing the cumulative cell load variation and cumulative intercellular moves. The quantity of parts, operation sequences, processing time, capacity of machines, and workload of machineries were considered as parameters. For the grouping of equipment, the modified artificial bee colony (MABC) algorithm is considered. The computational procedure of this approach is explained by using up to 40 machines and 100 part types. The result obtained from MABC is compared with the findings acquired from the genetic algorithm (GA) and ant colony system (ACS) in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
