Abstract

Robot penyapu ranjau merupakan robot yang karakternya menyerupai detektor ranjau yang dilakukan oleh robot. Teknologi yang di rancang ini disebut dengan Robot BM karena sesuai nama pembuatnya yaitu Bilqis dan NRS Muda, dimana robot ini mempunyai kemampuan untuk melakukan tugas seperti pendeteksian dan penyapu ranjau darat yang ditanam didalam tanah. Teknologi robot BM dilengkapi sensor atau detektor ranjau yang bekerja berdasarkan gelombang elektromagnetik jika menjumpai adanya ranjau maka signal ini akan ditandai oleh robot pada titik koordinat dan dihancurkan ditempat adanya ranjau dan informasinya dikirimkan pada frekuensi 600 MHz ke pengendali. Kelebihan dari teknologi robot ini dapat dikendalikan secara manual oleh operator ataupun autopilot dengan cara diprogram.

Abstract

The purpose of this study was to analyze the movement of the wings of a self-made eagle drone using the ANSYS method. The drone analyzed for the wing type moves to fly by being thrown when the brushless motor throttle moves the flapping of the wings at maximum rotation. The aerodynamic model used for data analysis in this paper is optimized to determine and improve the operational performance of the wings of eagle drones, especially in terms of stability and flight time. These two aspects are very important to determine the efficiency of drone performance. The method used for simulation analysis uses ANSYS 13. In the next step, the numerical results will be compared with the results during the experimental flight process. The conclusion of this study presents the main results of the simulation, namely numerical magnitude, main flight coefficient and flight time that affect stable flight efficiency.

Abstract

Acoustic metamaterials offer a promising pathway for reducing broadband noise generated by quadcopter propellers through tailored control of sound propagation. This study explores the integration of resonant acoustic metamaterial structures around the propeller shroud to attenuate vortex-shear noise, and investigates wave-redirection metamaterial lattices that steer acoustic energy away from sensitive directions. Numerical simulations and small scale experimental tests demonstrate that metamaterial rings incorporating Helmholtz type subwavelength resonators and anisotropic lattices can reduce peak sound pressure levels by up to 8–12 dB within the 300–900 Hz band typically dominated by rotor blade-pass frequency harmonics. Additionally, wave-redirection structures shift acoustic intensity lobes downward by 15–25 degrees without impairing aerodynamic performance. This work highlights the viability of acoustic metamaterials for future quieter drones used in civil, industrial, and environmental monitoring applications

Abstract

The rapid evolution of radar-based surveillance and targeting systems poses significant challenges to the survivability of unmanned ground vehicles (UGVs) operating in contested electromagnetic environments. This study presents the implementation framework of a wideband Radar Electronic Countermeasure–Electronic Counter-Countermeasure (ECM–ECCM) system integrated into an NRSM-class UGV, operating across a frequency range of 27 MHz to 10 GHz. The proposed system adopts a modular and software-defined architecture, enabling adaptive threat detection, real-time response, and electromagnetic resilience. The research focuses on system design, integration methodology, and performance evaluation using defined electronic warfare metrics. The results demonstrate that wideband ECM–ECCM integration significantly enhances UGV survivability and operational effectiveness against modern radar threats.
