Summary

We are developing smart robotic systems to improve efficiency and yield of farm operations. Our goal is to provide specialty crop growers with a data-driven deployment strategy that makes synergistic use of a networked robotic system working interactively with a human scout.

First, we have developed a lightweight and self-contained multi-spectral 3-D imaging system that has been deployed using unmanned aerial vehicles (UAVs), ground vehicles, and carried by a human scout. Acquired data have been used to train statistical models enabling persistent monitoring of crop yield, morphology, and health.

Second, we are developing the framework and algorithms to deploy multiple UAVs that can collaborate with and be controlled by a single human scout.

Finally, an agricultural decision support system (AgDSS) is being developed to facilitate annotation of field data acquired by our systems, and introspection of learned predictive models. Our technology stack will enable a human scout and a swarm of co-robots to operate in concert over extended periods while accommodating constraints on sensing, navigation speeds, and power consumption.

Agricultural decision support system (AgDSS)

Decision support systems are key to data-driven discovery. We have developed an open-source web-based agricultural decision support system for labeling and annotation of fruits, and visual symptoms of biotic stresses. Explore the AgDSS at the following site (requires registration).
