Abstract

Peningkatan perhatian global terhadap isu lingkungan dan kebutuhan mendesak untuk mengurangi emisi gas rumah kaca telah menyoroti pentingnya mengurangi ketergantungan pada bahan bakar fosil, terutama dalam sektor transportasi. Adapun, penelitian ini menyoroti potensi konversi kendaraan berbahan bakar minyak ke motor listrik, dengan fokus pada dinamo Brushless Direct Current (BLDC) sebagai solusi yang ramah lingkungan dan efisien. Motor listrik, terutama yang menggunakan dinamo Brushless Direct Current (BLDC), menawarkan keuntungan dalam hal efisiensi energi dan pengurangan emisi. Dinamo BLDC, yang mengubah energi listrik dari baterai menjadi gerakan mekanis tanpa memerlukan sikat karbon, menunjukkan efisiensi tinggi dan daya tahan yang baik. Namun, tantangan dalam perancangan dinamo BLDC meliputi pemilihan material yang tepat, integrasi dengan sistem konversi, serta aspek keamanan, pemeliharaan, dan biaya produksi. Penelitian ini mengidentifikasi dan mengatasi tantangan tersebut melalui desain yang komprehensif, melibatkan pemilihan material, perancangan komponen seperti stator dan rotor, serta integrasi sistem wiring. Hasil penelitian menunjukkan bahwa desain dinamo BLDC yang baik dapat meningkatkan efisiensi dan keandalan motor listrik, mendukung transisi menuju teknologi yang lebih ramah lingkungan dan berkelanjutan dalam sektor transportasi.

Abstract

Thermodynamics is often considered difficult for students to grasp because it involves abstract concepts that are challenging to visualize without visual aids or physical demonstrations. This research involves the design of a mini power plant trainer as a teaching tool to visualize basic thermodynamics concepts, such as heat transfer, conversion of heat energy into mechanical energy, phase change from steam to liquid, and thermal efficiency. The trainer is designed according to the requirements of the system provided by the thermodynamics lecturer at the State University of Padang, taking into consideration the teaching material and safety aspects. The power plant trainer consists of four main components, including a boiler with a 15-liter water capacity equipped with an automatic sensor stove that can shut off when it reaches 4 bars of pressure and restarts when it drops below 4 bars, a single propeller turbine, a 12-volt generator, and a vertical condenser with coolant flow in the same direction as the steam flow. The testing results of the trainer yielded a boiler efficiency of 46%, thermal efficiency of 21%, with the steam power generated by the boiler at approximately 1734 Watts, condenser power at 1478 Watts, cooling power to convert wet steam into liquid at 119 Watts, and turbine power at 375 Watts. The maximum electrical power reached 2.94 Watts with a voltage of 12 volts and a current of 0.21 amperes. It took 31 minutes to heat 15 liters of water in the boiler to steam with a temperature of 146°C and a pressure of 58 Psi. The trainer can be operated (can rotate the generator) for 4 minutes until the steam pressure drops to 20 Psi. Based on the testing results, the trainer can be operated smoothly and is capable of illustrating difficult thermodynamics concepts that are hard to visualize. Therefore, in an effort to enhance the quality of learning, this trainer can be used as a simulation tool for thermodynamics education.

Abstract

The increasing integration of mobile robots in various industries necessitates efficient navigation strategies amidst dynamic environments. Path planning plays a crucial role in guiding mobile robots from their starting points to target destinations, contributing to automation and enhancing human-robot collaboration. This study focuses on devising a tailored path-planning approach for a fleet of mobile robots to navigate through dynamic obstacles and reach designated trajectories efficiently. Leveraging particle swarm optimization (PSO), our methodology optimizes the path while considering real-time environmental changes. We present a simulation-based implementation of the algorithm, where each robot maintains position, velocity, cost, and personal best information to converge towards the global optimal solution. Different obstacles consist of circles, squares, rectangles, and triangles with various colors and five handle-points used. Our findings demonstrate that PSO achieves a global best cost of 5.1017, indicative of the most efficient path, minimizing overall distance traveled.

Abstract

Navigation technology is essential in fields like transportation and logistics, where precise mapping and localization are critical. Simultaneous Localization and Mapping (SLAM) technologies, such as Hector SLAM, enable robots to map environments by detecting and predicting object locations using sensors like LiDAR. Unlike other SLAM methods, Hector SLAM operates without odometry, relying solely on LiDAR data to produce accurate maps. This study investigates the application of Hector SLAM in a differential drive mobile robot controlled via the Robot Operating System (ROS), with PID control managing the motor speeds. The research contribution is the integration of Hector SLAM with PID control to enhance mapping accuracy in environments without odometry data. The method involves testing the robot's mapping performance in an indoor environment, focusing on the impact of varying linear and angular velocities on the quality of the generated maps. The PID control was tuned to ensure stable speed values for the robot's differential drive motors. Results show that Hector SLAM, when combined with well-tuned PID control, generates highly accurate maps that closely match the actual environment dimensions, with minimal errors. Specifically, the mapping error was found to be within 0.10 meters, validating the effectiveness of this approach in non-odometric systems. In conclusion, the study demonstrates that Hector SLAM, supported by PID-controlled motor stability, is an effective solution for mapping in differential drive mobile robots, particularly in scenarios where odometry is unavailable.
