Design optimization is generated by optimizing the blade airfoil and blade cascade during development of the turbine blades. Blade airfoil is optimized to obtain optimum value of ratio of Lift coefficient Cl and Drag coefficient Cd, in the range of turbine operation by utilizing of XFOIL that controlled via MATLAB. These airfoils are used to develop the blade cascade. To increase the benefits of fluid flow passing through the turbine blades, the analysis and optimization of the blade cascade is conducted. Vortex panel method is used to analyze the fluid flow inside cascade to gain the maximum of the lift force, in order to optimize the potential power of the fluid that can be utilized by the turbine rotor. The cascade optimization is including arrangement of the incidence angle of the cascade to reduce cascade losses and blade loading by applying the concept of shock-free inflow. Numerical analyses are conducted to determine the performance of the designed turbine with the commercial CFD. The results of numerical simulations show that the turbine can be operated at a maximum efficiency of 91% at various ranges of flow rates.

Research paper thumbnail of An iterative approach in pose measurement through hand-eye calibration

Proceedings of 2003 IEEE Conference on Control Applications, 2003. CCA 2003., 2003

The process must be repeated for each operations and each time a robot is replaced. Hence, pose measurement is needed. In this paper, a camera mounted on the end-effecter is employed. Firstly, the position and orientation of camera with respect to the end-eflector is solved through AX=XB composition, which is known as Hand-Eye calibration. However, this paper proposed a modification with an alteration of notation for A and B in prior. An iterative approach is utilized to obtain X. Afterward, multi-stage and one-stage iterative approaches are proposed in pose measurement to eliminateangle displacementson each joint. The first one uses composition as in Hand-Eye calibration for each joint from the end-effector to robot base. The second one uses one iterative process to solve the entire angle displacements. Simulated data is presented for both results.

Dalam pendekatan langsung, robot digerakkan sampai pada posisi dan orientasi tertentu dengan langsung menggerakkan robot secara manual dengan tangan atau melalui panel kendali. Posisi selanjutnya di simpan di memori setelah mencapai posisi yang di inginkan. Namun, teknik ini sangat membutuhkan waktu lama. Adapun teknik yang mudah dan cepat adalah dengan meniru gerakan objek melalui sensor untuk di implementasikan langsung ke robot. Beberapa riset mengatasi hal ini dengan menggunakan position sensitive detector (PSD) ataupun dengan kamera stereo. Namun untuk melakukan hal ini diperlukan set-up awal yang cukup rumit dan tidak cocok untuk merekam gerakan alami. Karenanya, paper ini mengembangkan pelestarian gerak dengan menangkap gerakan tubuh manusia secara alami melalui Kinect. Selanjutnya gerakan yang terbaca direproduksi pada robot humanoid secara bersamaan. Selain itu, gerakan tersebut juga di rekam dalam database untuk menggerakan robot sesuai gerakan manusia maupun mengajarkan manusia seperti gerakan tari di kemudian hari. Dalam paper ini juga dikembangkan gerakan robot yang lembut serta mendekati kemampuan mata membaca perubahan gerakan. Metoda yang diusulkan telah di validasi dalam eksperimen dengan menangkap dan mereproduksi gerakan manusia pada robot dengan kecepatan 20Hz. Dimana waktu komputasi untuk setiap proses sekitar 340us.
