The machine operates using solar power stored in a rechargeable battery, driving cutting motors and a Bluetooth-controlled movement system. Users control forward, backward, left, and right movement through a mobile application, reducing manual labour and improving safety. The system consists of a solar panel (20W), 12V lead-acid battery, DC motors for movement and cutting, HC-05 Bluetooth module, L298N motor driver, Arduino Uno controller, and a robust chassis. Testing demonstrates continuous operation for 2.5 hours on a full solar charge, cutting efficiency of 85% on grass up to 15cm height, Bluetooth control range of 10 meters, and 60% reduction in operational cost compared to petrol-driven alternatives, making it eco-friendly and suitable for lawns, gardens, and playgrounds 08 01 2026 46 49 https://creativecommons.org/licenses/by/4.0/ 10.5281/zenodo.22847485 https://ijitest.org/article/ijitest-2026-009 https://ijitest.org/api/files/published/IJITEST-2026-009-published.pdf
