Abstract

Beberapa peneliti telah melakukan penelitian untuk meningkatkan efektifitas latihan seorang kiper sehingga dihasilkan sebuah alat bernama ball launcher atau pelontar bola. Penelitian yang sudah dilalukan pada ball launcher atau alat pelontar bola memiliki system yang kurang efisien, dimana pada proses pelontaran bola ke arah kiper alat perlu digerakkan ke titik penembakan bola, melakukan setting arah dan kecepatan lontar bola, memasukkan bola yang akan dilontarkan secara manual. Pada penelitian ini alat dikembangkan menjadi sebuah mobile robot yang dapat dikontrol pergerakannya, serta dapat melontarkan bola dengan mengatur arah dan kecepatan lontar bola oleh ball launcher secara otomatis menggunakan mobile application. Hasil pengujian mobile application didapatkan dengan menguji setiap tombol yang masing-masing tombol memiliki variable yang berbeda-beda, dan dapat terhubung dengan arduino melalui bluetooth serta dapat mengendalikan aktuator. Pada pengujian ini menggunakan gawang sepak bola yang terbagi menjadi sembilan bagian, sehingga pada mobile application juga terdapat sembilan tombol arah sasaran yang masing–masing titik memiliki sembilan setpoint sudut yang berbeda. Hasil yang telah diperoleh adalah data yang ditampilkan pada serial monitor arduino yaitu hasil dari mengkonversi data variabel dalam bentuk char ke desimal, yang sesuai dengan nilai dalam tabel ascii. Berdasarkan pengujian tersebut didapatkan bahwa desain dari sistem mobile application sudah sesuai dengan fungsi untuk mengendalikan mobile robot pelontar bola dan sudah bisa melakukan integrasi dengan mobile robot pelontar bola untuk mengendalikan pergerakan setiap actuator. Kata kunci: Sepak Bola, Ball launcher, Mobile robot, Mobile application.

Abstract

Legged robot is preferred choice for travesing uneven terrain. Robot leg can be positioned dynamically to achieve better locmotion. Detection of the leg contact point became more of essential part for the unpredictable course. The common method by deploying resistive force sensor provides a binary condition of whether the leg has touches surface. This paper explores the possibility of implementing air pressure sensor on a sensor system to provide more information at robot leg contact point. Air pressure sensor can provide a more wide and continuous range of value that fluctuates along the contact rate of the leg. Verification of the study uses single leg part of dog-type quardruped. The sensor testing gave the output value with average error of 1,3%. The pressure sensor provides readings at around ± 40ms with maximum readable pressure of 1,5 kPa.

Abstract

The increasing presence of inorganic waste such as plastic bottles and cans poses a serious environmental threat and demands efficient detection solutions. This study aims to develop a real-time detection and position estimation system for inorganic waste using the YOLO v4-Tiny algorithm combined with homography transformation. A total of 3,388 labeled images were prepared and augmented via the Roboflow platform. The detection model was trained using the Darknet framework, while homography was applied to estimate object positions in real-world coordinates. System performance was evaluated based on precision, recall, F1-score, mean Average Precision (mAP), and Intersection over Union (IoU). The results show a mAP of 86.43%, precision of 77%, recall of 90%, and an average IoU of 62.33%. The system achieved a frame rate of 3–5 FPS, demonstrating its potential for low-power embedded devices. This approach is suitable for real-time waste monitoring using computer vision in constrained environments.

Abstract

Quadruped, a robot that resembles four-legged animals, is developed for many purposes, such as surveillance and rescue. Such a caveat requires the robot to have the capability to overcome various terrain and obstacles. When moving across such a landscape, it is essential to maintain the robot's orientation steadily. Inclined terrains such as stairs have posed another challenge to the control strategy as the robot is unstable while climbing. Therefore, the contribution of this work is to address the need for heading control because of the relatively longer stairs used for the current competition compared to the past. The proposed control system simultaneously maintains the heading while keeping the body stable. The inertial measurement unit sensor carried by the robot would provide the pose needed for heading control calculations. The robot's heading becomes the base for the PD controller calculation. The final pose that stabilizes the robot while tackling heading error is a combination of correction from the PD controller and the stabilization part of the control strategy. Then, the leg servo angle determination deployed the inverse kinematics calculation from the suitable robot pose. The proposed method enabled the designed robot to maintain its heading with a 4.4-degree margin of error and stabilize the body. The quadruped also completes the stair climbing at the shortest time of 20 seconds with a speed of up to 5.5 centimeters per second.
