Abstract

The rapid development of robotics technology drives the need for efficient automation systems, particularly in the industrial and educational sectors. One widely developed implementation is the robotic arm that can mimic human movements to manipulate objects with precision. This research aims to design and build a robotic arm prototype based on an Arduino microcontroller with four servo motors as the main actuators. The methods used include stages of information gathering, system requirements analysis, mechanical and electronic design, hardware construction, programming using the Arduino IDE, and system testing. The research results show that a robotic arm system with four degrees of freedom (4 DOF) is capable of performing basic movements such as picking up, lifting, and moving objects quite well. The integration between mechanical systems, electronics, and software works optimally, with the microcontroller able to controlling the movement of the servo in a coordinated manner. The robot can also be operated in manual mode using a joystick or in automatic mode based on predetermined parameters. Tests show that the robot is able to lift loads up to 350 grams optimally, but experiences limitations with larger loads. The implication of this research is that the designed system can be used as an effective learning medium for understanding basic robotics concepts, particularly related to actuators, control systems, and system integration.

Abstract

This research stems from the need to understand the complex relationship between time-varying electric fields and electromagnetic waves, which often presents difficulties in simulating their propagation in various media. The primary focus is to develop a numerical model capable of predicting the dynamics of this interaction, thus enabling its use in antenna development and radiation evaluation. The applied method includes a Finite-Difference Time-Domain approach, which solves the fundamental equations stepwise in both the time and space domains. The results show that the model is capable of reproducing transverse propagation patterns with a high degree of accuracy and detecting strong mutual induction effects at high frequencies. These findings provide a foundation for improving the performance of electromagnetic devices, minimizing potential interference, and opening up new innovations in the telecommunications sector.
