Focus Areas
1) Agricultural Mechatronics Systems
We focus on the applications of robotics and remote sensing technologies for biomass estimation and precision crop management. Our work has explored innovative methods to estimate aboveground biomass in key forage crops such as alfalfa, bermudagrass, and tall fescue, using ground-based, aerial, and stereovision systems. By integrating techniques like crop surface modeling, vegetation indices, and vegetation coverage analysis, we aim to enhance the accuracy and efficiency of biomass assessment, providing crucial data to support informed decision-making in agriculture. These efforts contribute to optimizing resource use and improving overall crop productivity. This research area reflects our commitment to advancing smart agricultural technology to address the growing demand for sustainable and efficient farming practices.
2) Agricultural Mechanization and Equipment Development
Mechanizing root collar excavation for the management of armillaria root rot (ARR) in peaches. Armillaria root rot is a fungal disease that affects stone fruits including peaches. One of the cultural solutions to this disease is planting trees on berms and root collar excavation. Root collar excavation (RCE) is the process of removing soil around the tree trunk and exposing the root collar. We focus on developing mechanical means to level the berms between trees after two years of planting and developing precision tools for root collar excavation. Links to Multistate Project Armillaria Solutions and short and long-term approaches to manage ARR.
Our research in the area of tractor safety, we developed and tested a rollover detection and emergency notification system, enhancing response times in hazardous situations. Additionally, our work on mobile phone sensing has advanced data collection methods for scientific research and tractor safety through the SafeDriving application. We also applied numerical simulations to study interactions between cutting tools and biomass during preprocessing.
3) Energy and Environmental Sustainability
Our research focuses on developing innovative solutions for cleaner energy and resource conservation. We have conducted extensive engine testing, examining diesel engines running on tire oil, biodiesel, and water-biodiesel-diesel nanoemulsions to reduce emissions while maintaining efficiency. Additionally, we explored sustainable water harvesting from the atmosphere using solar-powered thermoelectric modules to address water scarcity. Our work also includes ultrasound-assisted oil extraction from oil seeds for biodiesel production and ultrasonic cutting of switchgrass and miscanthus for efficient biomass processing.
