Design, Fabrication and Implementation of Deweeding Robot

Robotics is the human interfaced machine which must be used for to fulfill the desired work where human practices are low. Generally design of a robot involves in various types of analyses that invariably include structural, numerical, kinematic, and dynamic experiments. A robot designed as a solution for weeding problems would have to consider all the stages of plant growth. Initially a detailed description of the framework of the proposed robot is provided for simplicity along with the known design parameters. The primary design parameter of ‘the robot and its cutting mechanism’ establishes certain geometric and structural constrains on the design of worm gear, worm and blades which is attached with motors for comprising the cutting mechanism of the robot. This relationship is studied in order to improve the speed of cutting the weeds by image processing of camera for the differentiation of the weeds and plants by the robot. A significant reduction in size is achieved by working on these variables which leads to the improvement in the functional aspects and reduces the innovation of bigger machine used for these weeding purposes in modern world. There are 3 motors in which 2 motors are used for movement and 1 motor is used for actuating the cutting mechanism. This whole mechanism is controlled by Arduino UNO controller and MatLAB software. Arduino UNO controls the movement of the robot and the MatLAB software controls the differentiation of the plants and the weeds depending on the task allocated to the robot. Keywords - deweeding robot; structural analysis of cutting mechanism; control architecture; machine vision; image processing based output.
