Scalable Autonomous Agronomical Smartbot 

Personal and medium scale farming has exhibited a declining trend over the past few decades. Individuals are facing demotivation to participate in farming activities due to time constraints and the superior effectiveness of large-scale farming. Nonetheless, there is a significant health concern associated with the consumption of these products. They are cultivated using artificial fertilizers and contain residues of insecticides and pesticides. The incorporation of automation has the potential to reinvigorate personal and medium scale farming by reducing the time demands and enhancing farming efficiency. The proposed solution, the Scalable Autonomous Agronomical Smartbot (SAASbot), strives to automate farming activities such as seed planting, watering, fertilization, and weed removal. Furthermore, it offers a scalable robotic platform tailored for personal to medium scale farming. This project presented the design and implementation of the SAASBot, along with the testing and validation of the system.
