Abstract

Humanoid research in Indonesia is quite a lot, but in reality only limited in kid-size proportional size, while for the Teen-Size is still rare. Research on the Teen-Size Humanoid robot requires more joints to be able to perform the movement compared to the size of Kid-Size, therefore required more complex modeling to determine the movement. With complete kinematics anlysis, the movement of the robot can be solved. With kinematic forward-invers, researchers can determine the movement of robots by controlling the motor parts that function as a joint on the robot. In this study, the modeling uses D-H parameter, because this modeling has been widely used, besides the calculation can be solved by computing. And then for the simulation can be done with V-REP software. Forward-invers kinematics can be implemented on the PID algorithm, in order to generate speed on the motor that can form an angle on the motor to make the movement. The result of this research is to obtain equation of matrix transformation from all body parts of robot. With the creation of this Humanoid Teen-Size robot, it is hoped that the research on Humanoid robot in Indonesia will be increasingly diverse and increasing, and can be used as a support and reference in the development of Humanoid Teen-Size next.

Abstract

Penelitian dan pengembangan Unmanned Aerial Vehicle (UAV), banyak sekali fokus penelitian dan pengembangan yang akan dilakukan, salah satunya pada sistem propulsi. Sistem penggerak ini dibagi lagi menjadi beberapa komponen penting yaitu motor, kontroller, dan baling-baling. Penelitian ini fokus pada bagaimana mengkarakterisasi motor UAV dan membuat uji propeller Thrust Bench yang dapat digunakan untuk sistem propulsi UAV dengan berbagai jenis propeller. Penelitian ini diawali dengan merancang bagian mekanis dari bench test kemudian menganalisanya dengan software simulasi komputer untuk melihat kekuatan dan ketahanan dari bench test. Setelah itu tahap selanjutnya adalah proses pembuatan desain yang telah dirancang kemudian dirakit. Setelah perakitan bench test selesai, pengujian sistem propulsi UAV dan pencatatan data gaya dorong, RPM, tegangan, dan arus untuk karakterisasi motor dapat dimulai. Hasil pengujian data diperoleh karakteristik motor yang telah diuji baik secara langsung menggunakan uji dorong bangku. Hasil karakteristik data pada penelitian ini yang nantinya dapat diolah kembali sesuai kebutuhan masyarakat atau penelitian lebih lanjut.

Abstract

Beberapa peneliti telah melakukan penelitian dan pengembangan sebuah alat berupa Ball Launcher. Penelitian yang telah dilakukan masih terdapat beberapa keterbatasan yaitu, pada saat hendak menembak atau melontarkan bola ke gawang, pengaturan arah alat harus dilakukan dengan cara manual, jika ingin mengubah pengaturan kecepatan dari pelontar, pengoprasiaanya masih menjadi satu kesatuan pada alat tersebut dan untuk memindahakan alat tersebut masih dengan cara manual. Pada penelitian ini, dikembangkanlah sebuah mobile robot pelempar bola yang dapat melontarkan bola ke arah yang dapat diatur, baik ke arah horizontal maupun vertikal secara otomatis. Untuk memindahkan  mobile robot pelempar bola dapat dioperasikan melalui aplikasi yang terinstal di handphone. Hasil dari penelitian ini, bahwa alat dapat melontarkan bola dari titik pinalti ke arah gawang sebanyak 71 kali, dengan total tembakan tepat sasaran sebanyak 67 kali dan tembakan tidak tepat sasaran sebanyak 4 kali. Alat dapat mengarahkan lontaran bola secara horizontal maupun vertikal dengan baik, untuk pergerakan arah vertikal alat dapat berputar sebesar 30° ke arah atas gawang dan untuk pergerakan arah horizontal alat dapat berputar  sebesar 18° ke arah kanan maupun kiri gawang. Posisi alat dapat dioperasikan melalui handphone dan pergerakannya dapat berjalan dengan baik mengarah ke arah depan, belakang, kanan dan kiri alat di lapangan sepak bola.  Kata kunci—Mobile Robot, Pelempar Bola, Sepak Bola, Rancang Bangun.

Abstract

Lithium iron phosphate (LiFePO4) batteries offer advantages such as low cost, safety, environmental compatibility, and stability over repeated cycles. However, when subjected to high currents, this battery generates thermal issues, particularly when arranged in packs. This study aims to maintain the LiFePO4 80Ah battery within an optimal temperature range (20 °C – 40 °C) while minimizing pumping power. The proposed research introduces a serpentine channel with additional branches. The design variations include a gradient in branch spacing and changes in channel width. Each design is evaluated using dimensionless parameters representing maximum temperature, temperature uniformity, pumping power, and cooling efficiency coefficient. The best design from each variation is then compared with the conventional serpentine (CS) channel design, which is well-known for its superior thermal performance. The gradient variation reduces ????????????????∗ and ???????? by 0.07 and by 0.42, respectively, compared to the non-gradient channel design, at a Re 400 and a C-rate 3 C. The design with the largest channel width reduces ????????????????∗ by 0.57 or 11.32 °C compared to the design with the smallest channel width. At a Re 1000 and C-rate 3 C, the reduction in ????????????????∗ for the proposed channel design compared to the CS design is 0.017. In terms of the friction factor (????), the proposed design is 0.0149 lower than the CS design. The results indicate that the thermal performance of the proposed channel design is better than that of the CS design, with reduced pumping power.
