MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541084718 A) filed by Palla Siva Kumari; and Mareddy Padma Lalitha, Khajipeta, Andhra Pradesh, on Sept. 6, 2025, for 'remote-controlled solar agricultural sprayer with onboard power system.'
Inventor(s) include Palla Siva Kumari; and Mareddy Padma Lalitha.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The proposed project presents the design and implementation of a solar-powered, remote-controlled agricultural sprayer vehicle aimed at promoting sustainable and efficient pesticide or fertilizer application in farming practices. This innovative system integrates renewable energy and wireless control to assist farmers in reducing manual labor, minimizing chemical exposure, and enhancing field coverage. The system is divided into two key modules: a handheld remote control unit and an autonomous sprayer vehicle. The remote unit is equipped with a joystick, an Arduino Nano, and an NRF24L01 transceiver module to wirelessly transmit directional and spray control signals. The vehicle unit features an Arduino Uno as the central controller, which processes incoming commands and operates DC motors via a motor driver module for movement and a relay module to activate the spraying mechanism. A solar panel, connected to a solar charge controller, powers a rechargeable battery, enabling the vehicle to operate entirely on solar energy. This self-sustaining power system eliminates the need for external charging and ensures field operability in remote areas. The sprayer is driven by a 12V DC pump and nozzles, allowing targeted and uniform spraying across crops. This system demonstrates a low-cost, eco-friendly, and scalable solution for modern precision agriculture. Its modularity allows for future integration of sensors (e.g., obstacle detection or soil moisture sensing) and semi-autonomous control. The project highlights the potential of combining IoT, embedded systems, and clean energy to revolutionize conventional farming techniques."
