Design and Development of Multipurpose Agricultural Robot

This research paper introduces an autonomous agricultural robot powered by batteries, capable of performing a range of tasks, including ploughing, leveling, seed sowing, and seedling. The robot's frame is constructed from mild steel, and it uses DC motors for power transmission. A 3-DOF mechanism has been developed, with power and torque calculated at 0.01789 KW and 1.139 Nm, respectively. Structural analysis has been conducted on the chassis, plough, front roller, and back roller, resulting in deformations of 0.11049 mm, 0.038092 mm, 0.0004332 mm, and 0.00125 mm, respectively. For sowing wheat, a rotating drum with a hopper mechanism is employed, while a four-bar mechanism is used for seedling purposes. These components are then integrated into a remotely controlled robotic vehicle. The successful implementation of this robot demonstrates its potential to transform agricultural practices by offering efficient and precise automation for a variety of farming tasks. The objective of this project is to improve the quantity of crops while working in small spaces and gaining a better understanding of how agricultural robots function.
