Autonomous Intra-Row Weed Removal System

In this project I and Nishchay Sachdeva designed a low-cost Autonomous Weed Removal system for selected Indian agricultural fields. I developed a virtual CAD model, adhering to standard industrial DFM guidelines. Drafted a costing, simulation, analysis & design calculation report with a detailed manufacturing Manual.

Problem Statement

Availability of unskilled labor, willing to work in the agricultural industry is decreasing day by-day. Nevertheless, demand for laborers in agriculture remains, as it was earlier. As a result, farmers must pay more for laborers. However, there are systems or machines been developed in India which perform a few of the agricultural tasks (harvester, thresher etc.), but many activities still require human interaction or are not automated. Weed (unwanted crops) cutting is one of the tasks done by laborers by hand pulling or by weed removal tool operated by the laborer. Automating the process of weed removal and collection in the agricultural sector will be beneficial for farmer directly or indirectly in a long term manner.



A systematic design of an Autonomous weed removal system is being provided as a solution to the problem addressed. The objective of the proposed design is to cut weeds of size greater than 3 feet mechanically and collect the same with it, equipped with some additional features that will help farmers in optimizing the process. The design aims to eliminate the need of unskilled labor for the task of weed removal, and perform the task autonomously. The long-term intent of the project is to overcome the challenges faced by the existing solutions for weed removal and also to promote automation in the agricultural sector in an economically feasible manner for the farmers of India.
