PhD defence: Optimization and simulation algorithms in an agricultural robotic system

During his Ph.D. studies, Mahdi Vahdanjoo conducted a comprehensive assessment of an agricultural robot, taking into consideration its economic, operational, and environmental aspects.

Multiple in-field operations, including seeding and weeding, were closely observed, measured, and analyzed in comparison to conventional machinery. In addition, Mahdi Vahdanjoo formulated an optimization model specifically tailored to enhance the efficiency of the robot's in-field operation across different scenarios. This model considered various factors such as crop health, as determined by the NDVI index, as well as environmental impact, including CO2 emissions and the risk of soil compaction within a specified field sample. Furthermore, Mahdi Vahdanjoo pioneered the development of a predictive model that utilizes machine learning techniques to estimate the fuel consumption of the agricultural robot. To further enhance the analysis process, a simulation model was created to simulate the robot's operation under various scenarios.

The PhD study was completed at the Department of Agroecology, Faculty of Technical Sciences, Aarhus University.
