The CTEC Titans applied their coordinated air-ground robotics platform to pest and disease diagnostics in pistachios, California's top tree-nut export. A fixed-wing VTOL drone delivers 3D structural and NDVI mapping at orchard scale, identifying canopy stress and irregularities that warrant closer inspection. A 4WD rover then visits flagged locations to capture close-range imagery and gather soil samples through onboard probes. The system gives pistachio growers a scalable, data-rich monitoring workflow that ties high-altitude scouting to ground-truth diagnostics in a single coordinated package.
