Greenbot: A Solar Autonomous Robot to Uproot Weeds in a Grape Field

IJCSEC Front Page

Greenbot, an initial step towards automation of agricultural practices in India, is an autonomous robot that is designed solely to help farmers by identifying the weeds automatically and uprooting them from the agricultural field, especially grapevine field. The power source for this robot is provided through a solar panel along with a rechargeable battery, making it an environment friendly device. The primary actuator of the proposed system is a high speed blade known as a "Rotavator" that uproots the weed and buries it back into the soil from where it is uprooted. Weed identification through image processing techniques, controlling the rotavator based on image processing output and guiding navigation through Global Positioning System (GPS) and obstacle identification sensor are the important components of the proposed intelligent system. Raspberry Pi 2 board is used to implement these components, which is based on Broadcom BCM2836 SoC and includes a quad-core Cortex-A7 CPU running at 900 MHz and 1 GB RAM using Windows 10 IOT core. MATLAB software is used to implement the system.
