3. Problem Statement Significant challenges are faced by the farming industry of Pakistan, in the form of poor yield as well as inefficient use of basic resources including water, fertilizer, pesticide, etc. In order to overcome these problems, we propose robotics based precision agriculture solution that will allow farmers to utilize resources (e.g. water and fertilizers) effectively and efficiently. Undergraduate Final Year Project Presentation Dated: April 1, 2018

4. Proposed Solution An autonomous robot capable of performing following farming tasks:- Soil preparation using tillage tool Precise distribution of seed Watering User can remotely control and monitor the fields via Web application.
