Robot-Assisted Data Collection in Cyber-Physical-Human Systems for Agriculture

peschelJoshua Peschel | Assistant Professor | Dept. of Agricultural and Biosystems Engineering | Iowa State University

Abstract - Smart cyber-physical-human infrastructure has traditionally focused on the urban environment with applications related to water, energy, and transportation infrastructure. In this talk, Dr. Peschel will expand the definition of infrastructure to include agricultural and natural systems and present a suite of new robot-assistive technologies that leverage robotics and computer vision to broaden sensing and sense-making across these three different types of environments. Demonstrative case studies in each type of system will be presented, including robot-assisted measurements for water resources and applications for aerial telemanipulation. The material covered will illustrate how the strategic, user-focused design of robotics and automated systems to accomplish unique environmental data collection can enable better informed decision-making. This talk will be of interest to researchers and practitioners working in fields that include the agricultural and biological sciences, civil and environmental engineering, and computer science.

About the speaker Dr. Joshua Peschel is an assistant professor of agricultural and biosystems engineering and Black & Veatch Faculty Fellow at Iowa State University. He also holds courtesy appointments in the departments of Electrical and Computer Engineering, and Civil, Construction and Environmental 38Engineering. Dr. Peschel conducts research in the field of study he has founded called human-infrastructure interaction, which focuses on the evaluation, understanding, and design of co-evolving smart infrastructure systems. He broadly defines infrastructure to include agricultural, natural, and urban environments, and his work involves creating new technologies, data sets, and computational models for sensing and sensemaking in these three very different but often interconnected systems. His research program and students have been generously supported by the National Science Foundation, U.S. departments of Defense and Energy, the Bill & Melinda Gates Foundation, and a number of private industry partners.

Abstract - During the past decades, computer models that predict crop growth, development, and yield have become an integral part of agricultural research, outreach, and education. These simulation models have been implemented for many different spatial and temporal applications, ranging from gene-based crop modeling to climate change impact assessment and adaptation studies for policay recommendations. In this seminar, Dr. Hoogenboom will present a general overview of crop modeling and provide some specific applications of the international modeling platform DSSAT (Decision Support System for Agrotechnology Transfer).

 

Sustainable Cropping Systems Seminar in Waseca, MN

Tuesday, September 18 | 10:00 AM | Conference room, SROC (Waseca)

Crop Modeling as a Tool for Research and Extension

Abstract - Crop simulation models are a relatively new discipline in the field of agriculture. In general, crop simulation models can be used to predict the dynamic interaction between Genotype, Environment, and Management. When interfaced with decision support systems, crop models can also be linked to the economic components of the agricultural production system. Following evaluation with local experimental data, the crop models can be used to evaluate short- and long-term management practices for local environmental conditions. In this seminar, Dr. Hoogenboom will present a general overview of crop modeling and specific applications of the international modeling platform DSSAT (Decision Support System for Agrotechnology Transfer).
