Smart IOT Based Solar Robotic Grass Cutter and Water Sprinkler

Abstract: Traditional grass-cutting machines depend on manual operation and the use of fossil fuels, which leads to environmental pollution, increased operational costs, and greater physical effort. To overcome these limitations, this project proposes the design and implementation of a solar powered grass cutter integrated with a water sprinkler system. The robot operates wirelessly through a Bluetooth-based mobile application that enables remote control of its movement and functionality. The core of the system is the Arduino UNO microcontroller, which coordinates motor control, blade operation, and sprinkler activation. A solar panel is used to charge the onboard rechargeable battery, ensuring continuous operation using renewable energy. The drive mechanism employs DC motors for mobility, and the cutting blade is powered through a high-torque motor for efficient grass trimming. The water sprinkler system is interfaced with a mini water pump that can be activated as required. This system minimizes human intervention, promotes energy efficiency, and eliminates dependency on fossil fuels. The portable design and eco-friendly operation make the robot suitable for home gardens, institutional lawns, and small-scale agricultural fields. The integration of solar energy and wireless control enhances both sustainability and ease of use, contributing to smart automation in agricultural and domestic maintenance applications.
