ABSTRAK Langkah utama dan mendasar yang diperlukan untuk navigasi pada robot secara autonomous pada medan yang tak beraturan dan tidak diketahui keadaannya secara dinamis, setidaknya adalah identifikasi koordinat titik jalan (waypoint), tindakan yang harus dilakukan di titik jalan, identifikasi dimensi kerja, dan hambatan yang diketahui. Penelitian ini bertujuan untuk mengimplementasikan titik jalan otomatis (automatic waypoint) pada robot pencari potensi keberadaan korban pasca bencana, dilengkapi dengan kemampuan robot untuk navigasi dari titik awal berjalan mencari potensi keberadaan korban sebagai titik acuan hingga kembali ke titik awal (return trip) secara autonomous. Metode yang digunakan pada perancangan sistem merupakan pengembangan dari metode waypoint menjadi automatic waypoint untuk navigasi secara autonomous. Hasil yang didapat, robot mampu mendeteksi keberadaan korban maksimal dalam radius 3 meter di dalam simulasi reruntuhan. Ketercapaian rata-rata akurasi pembacaan posisi robot terhadap korban dan titik awal sebesar 6,76 meter. Kata kunci: robot, autonomous, automatic waypoint, korban, return trip. ABSTRACT There are necessary steps required for a robot to navigate autonomously on an unknown and uncertain environment. Those steps consist of the identification of the waypoint coordinates, the actions to be conducted, the identification of the environment’s dimension, and the known obstacles. This study aims to implement an automatic waypoint on a robot for searching the potential existence of post-disaster victims. The robot is equipped with the ability to navigate from the starting point to search for potential victims and then return to the starting point autonomously. We modified the existing waypoint method into an automatic waypoint for autonomous navigation. Results show that the robot is able to detect the presence of the victim within the maximum radius of 3 meters in the simulation of rubble (tables, chairs, wood and iron poles). The accuracy of robot in reading the position of the victim and the starting point is 6,76 meters. Keywords: robot, autonomous, automatical waypoint, victims, return trip.
ABSTRAKDari banyaknya strategi yang diusulkan untuk proses self-assembly pada swarm robotics, hanya beberapa grup riset berkonsentrasi di bidang ini yang mengusulkan proses paralel pada penggabungan antar robot. Tetapi, strategi ini hanya digunakan ketika sebuah robot memerlukan tumpuan dari dua robot atau lebih pada satu waktu. Berdasar pada kebutuhan untuk menyebarkan ratusan hingga ribuan robot pada satu swarm, strategi penggabungan antar robot satu-demi-satu memerlukan waktu yang sangat lama untuk diselesaikan. Di artikel ini, strategi self-assembly antar robot pada suatu swarm secara paralel diusulkan untuk mengurangi waktu proses self-assembly dengan menempatkan sejumlah robot di posisi tertentu. Saat penggabungan, robot-robot ini akan bergerak menempatkan dirinya sesuai dengan posisi akhir yang ditargetkan. Hasil menunjukkan bahwa strategi ini dapat mereduksi waktu proses self-assembly hingga setengah dari waktu yang diperlukan dengan proses penggabungan satu-demi-satu.Kata kunci: swarm robot, self-assembly, proses paralel ABSTRACTDespite the number of strategies proposed for self-assembly process in swarm robotics, only few research groups working in this area have proposed the parallel process of robots assembled each other. However, this strategy only works when a robot needs to be supported by two or more robots in a time. When deploying hundred to thousand robots in a swarm is required, the strategy of robots connecting to the structure of assembled robots in a one-by-one manner requires an extremely long time to accomplish. In this paper, a strategy of parallel selfassembly for robots in a swarm is proposed for reducing the self-assembly process time by placing a number of robots at particular positions. While connecting, they will move to position themselves appropriately to the targeted final structure. Result shows that this strategy can reduce the process of self-assembly time up to half of the time required for one-by-one process.Keywords: swarm robots, self-assembly, parallel process
The third mission of a university is a community service. Based on this mission, this paper presents the activity of community service. The activity was training for senior high school students and teachers. The subjects of the training are actuators, IoT, and IP address. These components or subsystems are very important basic industrial instrumentation for further automation. These subsystems are very correlated with each other. Some actuators are electric, hydraulic, and pneumatic types. There are many applications of IoT and IP addresses, such as smart grids and communications.
ABSTRAKPada kasus bencana alam, penyebaran robot pada area bencana sangat bermanfaat bagi tim SAR dalam proses pencarian korban. Khususnya, jika robot yang disebar merupakan robot otonom untuk meningkatkan proses pencarian, secara efektif dan efisien. Pada artikel ini, kami mengusulkan sebuah robot otonom untuk pencarian korban bencana yang ditanamkan metode waypoint dengan mengeksploitasi sensor, GPS dan divais komunikasi. Hasil yang didapat menunjukkan bahwa robot ini mampu mencari korban bencana secara otonom dengan mendeteksi pergerakan kecil dan temperatur korban. Kemudian, koordinat lokasi korban dikirim ke tim SAR untuk operasi penyelamatan. Robot ini juga mampu melakukan perjalanan pulang ke posko asal untuk pengisian daya ketika daya baterainya hampir habis.Kata kunci: robot otonom, waypoint, bencana, pencarian korban, perjalanan pulang ABSTRACTIn the case of disaster, the deployment of robots is immensely helpful for SAR team in the process of searching the victims. Especially, if the deployed robots are autonomous to enhance the searching process, effectively and efficiently. In this paper, we propose an autonomous robot for searching the disaster victims embedded by automatic waypoint method by exploiting sensors, GPS and communication devices. Result shows that this robot is able to search the victims autonomously by detecting their slight movement and temperature then sending the coordinates to the SAR team for the rescue operation. This robot is also able to do the return trip autonomously to the initial post for charging when its power is almost running out.Keywords: autonomous robot, waypoint, disaster, victim searching, return trip
