, Description:The present invention generally relates to an agricultural device. More specifically, the invention describes an automated agricultural assistant rover for assisting farmers.
BACKGROUND OF THE INVENTION

Robotics is a promising technology that contributes to almost every sector of the global economy, from medical to space study. Nevertheless, one sector that consistently lags behind is the agriculture. This is slightly mystifying because many farmers were used to the tools, heavy machinery and conventional agricultural techniques.
The usage of robotics related and automation technologies provides significant values to both farmers and agricultural field. These tools are used for common applications like seeding, spraying, fruit picking, plant classification, etc.
Automated agricultural tasks bring many benefits to the field which avoids unexpected or dangerous effects of chemical exposure which also helps to improve overall efficiency and productivity. Automation enables many advantages to farmers or land owners which makes the task held more accurate, uniform and less costly.
A scientific literature titled “Development of IoT Controlled Agri-Rover for Automatic Seeding”, [Aditya Vishwas Kanade, et al., 2017] describes an IoT enabled seed sowing rover which is controlled by an Arduino controller whereas the robotic motion is controlled by Internet ofT hings (IoT).
Another scientific literature titled “Design and Development of Agro Rover for Crop Monitoring”, [S. Janaki, et al., April 2019] describes a vision-based seed

sowing system whereas the Vision based system can be achieved by using camera and edges of land detected by using edge detection algorithm. Robot after found out the damaged leaf it can spray the pesticide. Soil moisture level, ultrasonic sensor values and other parameter values are sent to a cloud server and analyze the sensor values by using plots.
The currently existing agricultural rover device uses complex algorithms and components for performing automatic agricultural processes. Therefore, there exists a need to design and develop an automated agricultural device with less complexity and low cost.
