Solar Power Dual Grass Cutter Robot Automatic and Android App Based

Grass cutting is an essential activity in gardens, lawns, parks, and agricultural fields for maintaining cleanliness and proper plant growth. Conventional grass cutting machines generally operate using petrol engines or manual power which increases fuel consumption, operational cost, and environmental pollution. In addition, these machines require continuous human effort and supervision. To overcome these problems, a Solar Powered Dual Grass Cutter Robot with Automatic and Android App Based Control is proposed. The system uses solar energy as the primary power source which is stored in a rechargeable battery through a solar charging system. The robot can operate in two modes: automatic operation and manual control through an Android mobile application. The system consists of components such as a solar panel, battery, charge controller, microcontroller, motor driver circuit, DC motors, dual cutting blades, Bluetooth module, and Android mobile application. The dual blade cutting mechanism increases grass cutting efficiency and reduces the total operation time. The robot can move in different directions and cut grass automatically or by user control using a smartphone. This system provides an eco-friendly, energy-efficient, and cost-effective solution for lawn maintenance while reducing human effort and fuel consumption.
