Abstract

Abstract is arranged in one paragraph, single line spacing with Times New Roman Italic fonts. Abstract contains a brief narrative background to the problem, explaining the aims and objective of the research or study in general. A brief overview of method is presented along with how the analysis is performed. Results are presented in a concise and coherent manner according to the order of the method, the main points or important findings of the research. The abstract is then summarized into a conclusion according to the research objectives. Abstract is written in not more than 200 words. The entire manuscript is prepared in not more than 7 pages, in one column using Times New Roman fonts in 12 sizes with 4cm of left and top margin and 3 cm for right and bottom margin. Page numbers are written in Arabic numeral system and located in the bottom right corner of each page Grass area maintenance is generally carried out using conventional lawn mowers that require operators to remain close to the working area, thereby increasing safety risks. This study aims to design and evaluate a remote-controlled lawn mower based on the Arduino Mega 2560. The system consists of an Arduino Mega 2560, a FlySky FS-R6B receiver, BTS7960 motor drivers, two 12 V 250 W DC motors, and an ultrasonic sensor for obstacle detection. Performance testing was conducted to evaluate the machine's mobility, mowing capacity, control system response, and ultrasonic sensor performance. The results showed that the machine traveled 10 m in 7.54 seconds, 20 m in 13.62 seconds, and 30 m in 21.18 seconds. It also mowed an area of 25 m² in 28 minutes, achieving a mowing capacity of 53.4 m²/h. The remote control system functioned properly for all movement directions, while the ultrasonic sensor successfully detected obstacles within the specified detection range. Based on these results, the developed remote-controlled lawn mower operated in accordance with the intended design.
