How Well Do Pseudo-Rigid Body Models Capture Real Plants? In-Field Validation of Simulated Blueberry Canes
Hannah Kolano, Chelse VanAtter, Wei Yang +2
Many labor-intensive tasks in fruit production such as pruning require physically interacting with the plant (e.g., pushing, pulling, bending limbs, etc.). Due to increasing labor…
SeeTree -- A modular, open-source system for tree detection and orchard localization
Jostan Brown, Cindy Grimm, Joseph R. Davidson
Accurate localization is an important functional requirement for precision orchard management. However, there are few off-the-shelf commercial solutions available to growers. In th…
Compact robotic gripper with tandem actuation for selective fruit harvesting
Alejandro Velasquez, Cindy Grimm, Joseph R. Davidson
Selective fruit harvesting is a challenging manipulation problem due to occlusions and clutter arising from plant foliage. A harvesting gripper should i) have a small cross-section…
Machine Vision-Based Assessment of Fall Color Changes and its Relationship with Leaf Nitrogen Concentration
Achyut Paudel, Jostan Brown, Priyanka Upadhyaya +8
Apple(\textit{Malus domestica} Borkh.) trees are deciduous, shedding leaves each year. This process is preceded by a gradual change in leaf color from green to yellow as chlorophyl…
