Smart Multipurpose Agricultural Robot

Abstract

More than 60 percent of the population in India do agriculture as the primary sector occupation. At present, due to increase in shortage of labor, interest has raised for the development of the autonomous vehicles like robots in the agriculture field. A robot called “Smart Multipurpose Agricultural Robot” has been designed to minimize the labor of farmers in addition to increasing the speed and accuracy of the work. The Proposed system is designed with the multipurpose autonomous agricultural robotic vehicle which can be controlled through IOT, for soil parameters measurement, spraying pesticide on leaves is dependent on the height of the plants but not in free space, sow the seed in desired depth and provide required spacing between the seeds, detection of blockage of a seed and live video streaming of the field. The project was tested on the field. The robot is successfully able to move in all the directions. Monitoring the soil parameters like humidity, luminosity and also sensor position adjustment for monitoring temperature and moisture content in the soil are updated to Blynk App continuously. The user is able to control camera in any direction wirelessly through IoT for the live video streaming of the field. In seed sowing unit the user is capable of measuring the volume of the seeds in all the bins and also selecting size of the seeds for sowing. The seed sowing is capable to sow the seeds to the desired depth of 4 cm for the seeds whose diameter is < 4mm with the spacing of 5 inches and a desired depth of 5 cm for the seeds whose diameter is > 6mm with the spacing of 6 inches between the seeds. Pesticide spraying unit is capable of spraying pesticide only on the plant not in the free space with the maximum height of 4 feet.
