Abstract : The aim of this project was to develop a soft robotic actuator that could be used for research purposes. While there are several actuator products available, finding soft actuators on a global scale is challenging. To achieve this objective, we identified the areas of application, the terms of use, and the customer requirements. The requirements were specified quantitatively. Prototypes were created using silicone and molds, which were further developed over time. The production was carried out using two methods: rotation molding and actuator molding. We subjected the prototypes to various tests to evaluate their performance. This project provided us with insights into the design, production techniques, and characteristics of soft robotic actuators. Based on this knowledge, we were able to create a high-quality product.

Proje Öğrencileri: B. GÖÇENER, B. ÜNAL, M.U. TURHAN, B. KUTAY

Proje Danışmanı : Dr. Ece Aylı, Instructor M. Burkay SARI, Res.Asist. Eyup Kocak

Abstract : The oil temperature sensor in the existing hydraulic oil tank of the HMK 230 LC Excavator reads a value lower or higher than the temperature value it should measure. There are two different pipelines entering the hydraulic tank. These lines are the “Radiator Line”, where the oil is cooled and returned to the tank, and the “Line That Cannot Enter the Radiator Line”, where the oil returns directly to the tank without cooling. These lines have different temperatures, pressures, and flow rates. Therefore, the hydraulic oil in the tank does not mix homogeneously. This project aims to reduce the error margin of the measured temperature value by determining the optimum position of the hydraulic oil temperature sensor in the existing tank.

Abstract : Within the scope of the project supported by the ROBIT company, a scara robot with 5 functions was made in line with customer demands. The functions are drilling, laser engraving, pick and place, soldering and FDM. The robot is equipped with software with the ardiuino system and it performs all 5 functions without any problems with a deviation rate of 1 mm in the A3 position. Headings have been designed for the above-mentioned purposes, and technical drawings of all parts have been created.

(Bu Proje Biokido Medical Tarafından Desteklenmiştir.)

Proje Öğrencileri: O. ÇALISICI, S.A. KINACI, B. AKISOGLU, I. KOLTAN, M. YUKSEL

Proje Danışmanı : Dr. Ozgun Selvi

Abstract : The project covers project planning, production planning, test planning, design changes, re-production, re-testing, project final report, project presentation, and implementation plan. It outlines future work with determined deadlines and material procurement. Challenges in production planning include production capacity, utilization, and output balance. The test plan outlines testing approach, objectives, timelines, and resources. Changes in three primary factors were used when constructing the test plans. Design changes were made due to material availability, cost, and customer requests. The final design was produced and tested, with a conceptual design presentation and the creation of a Gantt chart. The project presentation covers six main topics and includes 3-D modeling of the test setup.

Proje Danışmanı : Dr. Turgut Akyürek

Abstract : The robot vacuum cleaner is the more advanced version of the vacuum cleaner. The robot vacuum cleaner is a cleaning tool consisting of more than one side brush, which works with the help of a motor, which is formed by the combination of sensors and brushes, and varies according to some designs. In this project, it has been designed and manufactured to meet customer requirements and to compete with other products in the market.Root sheets and assembly sheets were prepared for the mass production of the designed robot vacuum cleaner, but since it would be very costly to prepare the prototype according to this, the prototype used in the tests was produced with the 3d print method. Then assembly was made according to the assembly sheets.

Proje Öğrencileri: C.S. BURAN, Ö. A. KARABABA, T.Y. ÖZMEN, H. KÜÇÜKERGÖR, Y. NAMAL

Proje Danışmanı : Dr. Hakan Tanrıöver

Abstract : This study aimed to design a drop weight impact tester for low-energy and low-velocity impact testing and validate its performance through experimental validation. A low-energy and low-velocity impact tester was developed and tested using infrared sensors to compare the experimental results with theoretical calculations. The results showed that the tester functioned as expected, and the theoretical calculations were consistent with the experimental data obtained from the infrared sensors. These findings suggest that the designed drop weight impact tester is an effective tool for low-energy and low-velocity impact testing, with potential applications in material science, mechanical engineering, and related fields.

Proje Danışmanı : Dr. Ece AYLI, Dr. Ekin Özgirgin Yapıcı

Abstract : In this work, experimental study for heat transfer enhancement in a cavity with heat generation at the bottom is investigated. For heat transfer enhancement, different arrangement of fins are located at the bottom surface of the cavity with different non-dimensional geometric parameters in fully developed turbulent internal flow. The effect of geometric parameters on local convective heat transfer coefficient and Nusselt number is analysed for the Reynolds Number of 1125×103 and 4<d/t<5 ranges (distance between fins/fin thickness.)

Proje Öğrencileri: M.A. TÜRK, K. SONGOR, R. ÇAKAR, B. UÇAK

Proje Danışmanı : Dr. Samet Akar, Suat Bengür

Abstract : In this study, a dynamometer that can measure two directional cutting forces, feed force (Fx) and cutting force (Fy) by using strain gauge has been designed and developed. The orientation of octagonal rings and strain gauge locations has been determined to maximize sensitivity. The developed dynamometer is connected to a data acquisition system. Cutting force signals were captured and transformed into numerical form and processed using a data acquisition system consisting of necessary hardware and software. The obtained results of machining tests performed at different cutting parameters showed that the dynamometer could be used reliably to measure cutting forces.

Abstract : This experimental study aims to understand and control the cavity instabilities of structures of various angles and lengths developed with passive control techniques. An experimental setup was designed to examine the flow field inside the cavity in passive control geometries, to determine the position-dependent SPL values, and to select the most effective passive control structure, using a low subsonic flow of 4m/s. The results showed the effect of passive control structures and the most effective passive control structure was chosen.

Abstract : The aim of the project is to design and implement fan and fan test setup and perform tests to determine the performance of the fan. A fan with 2000 m3/h flow rate, and 150 Pa static pressure head was designed. Fan blades were manufactured by 3-D printing technique. Computational fluid dynamics simulations were performed o analyze the flow characteristics of the fan and using the CFD simulation results fan blade design was improved. A fan test system for low-capacity fans was also constructed. Test system was instrumented with devices to measure pressure difference, air velocity and noise level. Using the measured data, the fan performance parameters pressure increase, and efficiency were calculated as the function of flow rate and plotted.
