MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541112981 A) filed by Dr. Rashmi R. Deshpande; Dr. Sujay Routh; Murugesh MR; Nandan Kumar N; Praveen Gouda; and Bholenath, Bangalore, Karnataka, on Nov. 18, 2025, for 'a design and implement of smart agro-tech: onion leaf chopping and onion sorting system.'
Inventor(s) include Dr. Rashmi R. Deshpande; Dr. Sujay Routh; Murugesh MR; Nandan Kumar N; Praveen Gouda; and Bholenath.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The Smart Agro-Tech system automates onion leaf chopping and size-based sorting to reduce manual labour and improve efficiency in post-harvest processing. The onion leaf chopping mechanism uses a 12V 3A DC power supply connected through a toggle switch that manually controls two DC motors rotating in opposite directions one clockwise and the other anticlockwise. This dual rotation ensures uniform trimming of onion leaves. An LED indicator (with a 330 2 resistor) glows when the motors are active, confirming system operation. It uses a Raspberry Pi 4 Model B as the central controller, integrating camera-based image acquisition, real-time image processing, and motorized mechanical control. A Pi Camera captures images of onions on a conveyor belt, and OpenCV algorithms measure contour area to classify them as small, medium, or large. Based on the classification, DC motors operate cutting and sorting mechanisms through L298N motor drivers. This automation saves time, ensures uniform results, and offers a low-cost solution adaptable for small and medium-scale farmers. The invention bridges mechanical automation and machine vision to create a practical example of smart farming technology."
