Abstract

The development of technology in the military field has changed from time to time. This dynamic must be taken seriously because they are a challenge, and pose a potential threat to the sovereignty of the Unitary State of the Republic of Indonesia (NKRI), As well as the trend of the technology-based warfare today. So it has become a necessity for the Indonesian National Army (TNI) to accept it. One of the popular technologies today, war robt technology(warbo), and including multimodal robots with a variety of basic missions. Furthermore, developing a multimodal robot concept design that can fulfil TNI surveillance needs. The methodology used is in the form of interview, observations, comparison, and literature studies by applying system engineering theory and life cycle models. This research has successfully formulated user requirement objectivies which are then elaborated into robot design concepts including characteristic design, and architecture design of multimodal monitoring robots. The hardware on the robot is design differently from others because it has the ability to fly and walk on the ground. The robot is also conceptualised to have advantages in terms of durability with agility, silence, and operate with various terrain conditions. Equipped with sensors to see, hear, measure ambient temperature, and read surrounding conditions using camera sensors, where the robot moves autonomously equipped with GPS and Lidar can send data in the form of audio visual directly to the Ground Control System (command centre). The concept design of the multimodal monitoring robot called Tsunhan-14 is expected to be the basis for determining technical requirement and further developed into a national innovation that is utilized as part of the TNI’s war strategy.

Abstract

Soldier safety in modern military operations demands weapons systems capable of safe and precise This study presents the reactivation of a previously non-functional Remote Controlled Weapon Station (RCWS) by implementing a Proportional Control (P-control) system using the Teensy 3.5 microcontroller to regulate motor movement on the azimuth and elevation axes. The RCWS system was developed using a distributed multi-microcontroller architecture, in which the Teensy 3.5 serves as the main controller connected to the Arduino Mega 2560 Pro for joystick management and the Arduino Nano for reading the 1024 PPR rotary encoder. The setpoint values were obtained from the joystick, while the actual position was measured by the rotary encoder to calculate the error and generate a proportional PWM control signal. Experimental results indicate that a larger error between the setpoint and actual position produces a higher PWM signal, enabling the system to deliver linear, stable, and precise motor responses. Furthermore, the implementation of limit control on the elevation axis (420 ≤ θ₂ ≤ 600) effectively prevents excessive movement and protects the mechanical structure. Overall, the reactivated RCWS operates in real-time with stable serial communication, and proven reliability, offering potential for further development through the integration of PID control, fuzzy logic, or computer vision tracking to enhance the performance of remote weapon control systems. Abstrak Keselamatan prajurit dalam operasi militer modern menuntut sistem persenjataan yang mampu beroperasi secara aman dan presisi. Penelitian ini membahas reaktivasi sistem Remote Controlled Weapon Station (RCWS) yang sebelumnya tidak berfungsi, dengan fokus pada penerapan kontrol proporsional (P-control) berbasis mikrokontroler Teensy 3.5 untuk mengatur pergerakan motor pada sumbu azimut dan elevasi. Sistem RCWS dirancang menggunakan arsitektur terdistribusi berbasis multi mikrokontroler, di mana Teensy 3.5 berperan sebagai pengendali utama yang terhubung dengan Arduino Mega 2560 Pro sebagai pengelola joystick dan Arduino Nano sebagai pembaca rotary encoder 1024 PPR. Nilai setpoint diperoleh dari joystick, sedangkan posisi aktual dibaca oleh rotary encoder untuk menghitung error dan menghasilkan sinyal kendali PWM secara proporsional. Hasil pengujian menunjukkan bahwa semakin besar error antara setpoint dan posisi aktual, semakin besar pula sinyal PWM yang dihasilkan, sehingga sistem mampu memberikan respon motor yang linier, stabil, dan presisi. Penerapan mekanisme limit control pada sumbu elevasi (420 ≤ θ₂ ≤ 600) berhasil mencegah pergerakan berlebih dan menjaga keamanan mekanik sistem. Secara keseluruhan, sistem RCWS yang direaktivasi berhasil beroperasi secara real-time dengan komunikasi serial yang stabil, serta dapat dikembangkan lebih lanjut menggunakan metode PID control, fuzzy logic, atau computer vision tracking untuk meningkatkan performa sistem kendali senjata jarak jauh
