Abstract

In the ever-increasing development of technology, the field of robotics has become one of the most promising fields, both in the industrial world, education, and technological research. Robotics not only increases work efficiency, but also encourages innovation in various sectors. This project aims to develop a multi-purpose wheeled robot equipped with a 4 servo mechanical arm, which functions to support the robot's operational capabilities in various simple tasks such as picking up and moving objects. The main objective of this project is to understand and implement a robotic control system using an Arduino Uno microcontroller, an L298N motor driver, and integration with a wireless PS2 control interface. In more detail, this research aims to: (1) build a four-wheeled robot that can be controlled wirelessly using a PS2 controller; (2) implement a 4 servo arm system as an additional actuator to enhance the robot; and (3) integrate hardware components such as an Arduino Uno and an L298N motor driver into a robot control system. The methodology in this research includes the hardware and software design stages, programming using the Arduino IDE, and integration of all components such as DC motors, SG90 servos, wireless PS2 control modules, and power supplies. Testing was conducted to observe the system's response to input from the controller. The implementation results show that the robot can operate stably. The robot is able to respond to commands well and accurately, both in terms of basic movements using wheels and in moving its servo arm.

Abstract

Automatic and adaptive fan speed control is an important aspect in maintaining the stable performance of electronic devices, reducing energy consumption, and preventing damage due to excessive temperature. This research focuses on the design and implementation of a DC fan speed control system that utilizes a temperature sensor in the form of a KSD type thermostat as the main regulator. The system is designed to be able to operate at three different speed levels, which are automatically activated based on certain temperature points, namely 31°C, 40°C, and 55°C. Thus, the fan only works according to actual needs, so its use is more efficient. The research method used is a laboratory experimental approach, which includes three main stages, namely electronic circuit design, hardware component assembly, and functional testing of the system. Trials are carried out to ensure that the system is able to respond to temperature changes appropriately and consistently. The test results show that the control system built works according to the design, where the fan can adjust its rotational speed automatically when the temperature reaches a predetermined threshold. Overall, this system has a simple design, is robust to temperature changes, and is effective in controlling heat in electronic devices. Its implementation has the potential to provide significant benefits in the form of energy efficiency, more optimal fan power utilization, and extended device lifespan through stable operating temperature control. This research could form the basis for the development of smarter and more efficient cooling systems in the future.

Abstract

This research focuses on the design, implementation, and testing of a DC-to-AC inverter circuit utilizing an astable multivibrator configuration. The primary objective of this study is to convert a 12-volt DC input voltage, typically obtained from a battery or other low-voltage sources, into a standard 220-volt AC output voltage suitable for powering common household and industrial appliances. Inverters play a crucial role in power electronics, enabling the efficient use of renewable and portable energy systems. The research method involved several stages, beginning with circuit design based on an astable multivibrator schematic. Components including C1815 and TIP31C transistors, resistors, capacitors, and a step-up transformer were carefully selected and assembled onto a printed circuit board (PCB). After the circuit was successfully constructed, testing was carried out by supplying a 12-volt DC source and measuring the resulting voltage values using a digital multimeter. The experimental results demonstrated that the inverter circuit was able to effectively convert the input voltage into an alternating output, producing an average of 228 volts AC. This indicates that the designed circuit not only functioned according to expectations but also operated with a high degree of accuracy. Overall, the findings highlight the practicality and reliability of the astable multivibrator inverter for low-power conversion applications. Furthermore, the study contributes to a deeper understanding of inverter circuit design and offers a foundation for further development of efficient, low-cost, and accessible power conversion systems.
