Summer Intern

May 2021 – Jul 2021 · 2 mos

> As a Research Intern at the Indian Institute of Technology, Ropar, I developed an agricultural drone prototype that can perform various tasks such as weed removal, sowing, and spraying of pesticides using Raspberry Pi and Arduino.
> I have worked in Agritech and designed a Crop hopper ( a robot that can jump and use a drone for extended range) that can perform tasks such as Weed Removal, Sowing, and Precision Spraying of pesticides. Along with this, the proposed design was made to be deployed in the Rice Paddy field. It can detect any disease in the crop using the Image Processing Model. A user-friendly application was also developed to easily control the Crop Hopper.
