    Kurzfassung: Currently, Tempura shrimp consumption is very high in most Japanese restaurants all over the world. There are many companies that produce Tempura shrimp to provide for many restaurants as well as to sell in many supermarkets in many countries. In fact, the benefits of this product are enormous for the seafood industry in Vietnam as well as in other countries. However, most of the companies that produce the Tempura shrimps manually by workers. There are a lot of workers who fry shrimp manually to keep the company productive. The quality of this product also bases on the skill of the workers. And, to satisfy the condition of mass production, the enterprise also needs the very large area to set up the workplace for the workers. Secondly, this situation leads to the practical results that the quality of Tempura shrimp is not identical, unstable and the amount of waste is very high. Therefor, the requirement for the application of automatic control system in this tempura field can help the company to solve these difficult problems. This issue is the primary focus of this document. It is the situation of the Tempura fried shrimp companies which lead them to implement automated systems to replace unskilled workers. This paper presents the design of the whole semi automation single-side Tempura shrimp frying production line to propose some innovation about the shrimp tempura frying process. The entire Tempura semi automation production line consists of 3 main modules. Each module can operate as an independent machine. The workers just put the coated shrimp in the molds and then the frying process will perform the remaining steps automatically. The first module (Module 1) is the shaping module or the first time frying module. The powder solution also installed with this module. The second module (Module 2) is the finished frying module. Finally, the oil drainning module (Module 3) using the technique of the hot heating airflow system to drain the excess oil inside the Tempura shrimps.

    Kurzfassung: Nowadays, the applications of automatic control systems have been developing very fast in many diversify of the industry fields. One of the most significant industry that is needed to care and focus to develop this automation technology in order to reduce the huge number of workers and increase the productivity is the seafood industries. Normally, the seafood industry has a lot of workers to carry out everything manually. There still remain many research topics relating to this field to help this industry to develop in the trend of 4.0 ages. The semi–automation shrimps Tempura frying production line is a system to make Tempura shrimps with high productivity. The workers simply put the shrimps into the serial of chain frying molds and the system will automatically do the whole production process to produce the completed Tempura shrimps. The whole process to produce Tempura shrimps includes the following steps: (1) Shaping shrimp and cover with powder solution by automatic powder solution spraying system; (2) Complete frying to make the shrimps to be cooked; (3) Oil draining system to remove the remain oil inside the shrimp and the powder cover. Then the finished products will be put into the frozen system to preserve. The whole production line will be separated into 3 main modules: Module 1: The shaping module (first time frying) and powder solution spraying module; Module 2: The deep fry module (second time frying); Module 3: The oil draining module. This paper introduces about the control system for each module and the controller of the whole system to make a complete semi-automation shrimp tempura frying production line. Some controller technology as On/Off, PID control algorithms are proposed to apply for the whole production line as: speed control of the stainless-steel chain conveyors, temperature control of the cooked tanks, quantitative control of the powder solution amount to be sprayed on the shrimps, the oil draining conveyor speed, the heat and air flow control of the oil draining module.

    Kurzfassung: Research and development on a global scale have been conducted on overhead hoist transportation systems (OHTSs) in recent years. The majority of these systems are utilized in manufacturing facilities that are either semiautomated or fully automated. By using stochastic models to evaluate medication distribution and product delivery processes in automated delivery systems, hospitals can reduce patient waiting times and drug response times. Warehouses are being transformed into fully automated fulfillment factories by using conveyors and shelf-lifting mobile robots, which reduce waiting times and improve efficiency. Modern warehouses are increasingly becoming fully automated fulfillment facilities as a response to the significant development of e-commerce. A significant number of organizations are using mobile robots or conveyor systems to transport shelves. The parts-to-picker model is used to transport stock-keeping units (SKUs) to stationary pickers at picking workstations. The aim of this study is to analyze and organize the relationship between transportation system families. They are utilized in various fields, such as warehouses, hospitals, airports, cross-dockings, etc. Furthermore, this study categorizes a range of synchronization issues that arise from minor variations in workstation configurations within different warehouse settings. Next, we identify a multistation ATS (automatic transportation system) that switches lines to different stations by using overhead conveyors and active line-switching devices. Vietnam’s automated freight problem can be solved with this potential solution. Our study’s findings suggest that enhancing the workstation layout can significantly enhance throughput performance. As a result, the benefits of synchronization can surpass those provided by other well-studied decision tasks.

    Kurzfassung: This paper presents a model of a three-joint (four links) carangiform fish robot. The smooth gait or smooth motion of a fish robot is optimized by using a combination of the Genetic Algorithm (GA) and the Hill Climbing Algorithm (HCA) with respect to its dynamic system. Genetic algorithm is used to create an initial set of optimal parameters for the two input torque functions of the system. This set is then optimized by using HCA to ensure that the final set of optimal parameters is a “near” global optimization result. Finally, the simulation results are presented in order to demonstrate that the proposed method is effective.

    In: Tekstilec, University of Ljubljana, Vol. 65, No. 1 ( 2022-02-11), p. 67-80
    Kurzfassung: This study presents an algorithm to automatically extract the size and body shape of a 3D scanned model. The methods used in this research include factor analysis, linear regression equation, cluster analysis, and discriminant analysis. These are used to analyze the body’s shape and choose the best primary dimensions for establishing the sizing system table. Authors use fuzzy logic to establish the mathematical model. In this model, the input variables are the inseam height and the neck girth measurements, and the output variables are the numbers of the human size coding and body shape. In addition, the rotation matrix and the optimal function are used to write an algorithm to estimate the neck girth and inseam measurements. Furthermore, a simple approach based on vertices and surface normal vector data, together with optimal searching, is adapted to estimate the primary dimensions. This estimation algorithm, combined with the fuzzy logic model, makes the automated process of extracting the size and body shape possible. The findings of the study suggest a new research method for quickly informing people about their body shape. This supports purchasing clothes and designing tailored clothing. The automatic algorithm will be very useful for buying clothes face-to-face or online.

    Kurzfassung: The fish robot is a new type of biomimetic underwater robot which is developing very fast in recent years by many researchers. Because it moves silently, saves energy, and is flexible in its operation in comparison to other kinds of underwater robots, such as Remotely Operated Vehicles (ROVs) or Autonomous Underwater Vehicles (AUVs). In this paper, we propose an efficient advanced controller that runs well in controlling the motion for our fish robot. First, we derive a new dynamic model of a 3-joint (4 links) Carangiform fish robot. The dynamic model also addresses the heading angle of a fish robot, which is not often covered in other research. Second, we present a Sliding Mode Controller (SMC) and a Fuzzy Sliding Mode Controller (FSMC) to the straight motion and turning motion of a fish robot. Then, in order to prove the effectiveness of the SMC and FSMC, we conduct some numerical simulations to show the feasibility or the advantage of these proposed controllers.

    Kurzfassung: Biomimetic robot is a new branch of researched field which is developing quickly in recent years. Some of the popular biomimetic robots are fish robot, snake robot, dog robot, dragonfly robot, etc. Among the biomimetic underwater robots, fish robot and snake robot are mostly concerned. In this paper, we study about an optimization method to find the design parameters of fish robot. First, we analyze the dynamic model of the 3-joint Carangiform fish robot by using Lagrange method. Then the Genetic Algorithm (GA) is used to find the optimal lengths’ values of fish robot’s links. The constraint of this optimization problem is that the values of fish robot’s links are chosen that they can make fish robot swim with the desired straight velocity. Finally, some simulation results are presented to prove the effectiveness of the proposed method

    Kurzfassung: Biological fish can create high forward swimming speed due to change of thrust/drag area of pectoral fins between power stroke and recovery stroke in rowing mode. In this paper, we proposed a novel type of folding pectoral fins for the fish robot, which provides a simple approach in generating effective thrust only through one degree of freedom of fin actuator. Its structure consists of two elemental fin panels for each pectoral fin that connects to a hinge base through the flexible joints. The Morison force model is adopted to discover the relationship of the dynamic interaction between fin panels and surrounding fluid. An experimental platform for the robot motion using the pectoral fin with different flexible joints was built to validate the proposed design. The results express that the performance of swimming velocity and turning radius of the robot are enhanced effectively. The forward swimming velocity can reach 0.231 m/s (0.58 BL/s) at the frequency near 0.75 Hz. By comparison, we found an accord between the proposed dynamic model and the experimental behavior of the robot. The attained results can be used to design controllers and optimize performances of the robot propelled by the folding pectoral fins.
