A Measurement-Driven Digital Twin Architecture for Plant-Level Biomass Estimation and Growth Forecasting in Hydroponic Systems
Morgan Mayborne, Abhisesh Silwal, George Kantor
Alternatives to soil-based horticulture, such as hydroponics, have been developed to respond to food distribution concerns for dense urban centers. A new system was developed to tr…
Active Robotic Perception for Disease Detection and Mapping in Apple Trees
Hayden Feddock, Francisco Yandun, Srđan Aćimović +1
Large-scale orchard production requires timely and precise disease monitoring, yet routine manual scouting is labor-intensive and financially impractical at the scale of modern ope…
MapForest: A Modular Field Robotics System for Forest Mapping and Invasive Species Localization
Sandeep Zachariah, Francisco Yandun, Sachet Korada +1
Monitoring and controlling invasive tree species across large forests, parks, and trail networks is challenging due to limited accessibility, reliance on manual scouting, and degra…
T-REX: Vision-Based System for Autonomous Leaf Detection and Grasp Estimation
Srecharan Selvam, Abhisesh Silwal, George Kantor
T-Rex (The Robot for Extracting Leaf Samples) is a gantry-based robotic system developed for autonomous leaf localization, selection, and grasping in greenhouse environments. The s…
Autonomous Robotic Pepper Harvesting: Imitation Learning in Unstructured Agricultural Environments
Chung Hee Kim, Abhisesh Silwal, George Kantor
Automating tasks in outdoor agricultural fields poses significant challenges due to environmental variability, unstructured terrain, and diverse crop characteristics. We present a…
SplatSim: Zero-Shot Sim2Real Transfer of RGB Manipulation Policies Using Gaussian Splatting
Mohammad Nomaan Qureshi, Sparsh Garg, Francisco Yandun +3
Sim2Real transfer, particularly for manipulation policies relying on RGB images, remains a critical challenge in robotics due to the significant domain shift between synthetic and…
3D Skeletonization of Complex Grapevines for Robotic Pruning
Eric Schneider, Sushanth Jayanth, Abhisesh Silwal +1
Robotic pruning of dormant grapevines is an area of active research in order to promote vine balance and grape quality, but so far robotic efforts have largely focused on planar, s…
Autonomous Apple Fruitlet Sizing and Growth Rate Tracking using Computer Vision
Harry Freeman, Mohamad Qadri, Abhisesh Silwal +4
In this paper, we present a computer vision-based approach to measure the sizes and growth rates of apple fruitlets. Measuring the growth rates of apple fruitlets is important beca…
Unsupervised Statistical Learning for Die Analysis in Ancient Numismatics
Andreas Heinecke, Emanuel Mayer, Abhinav Natarajan +1
Die analysis is an essential numismatic method, and an important tool of ancient economic history. Yet, manual die studies are too labor-intensive to comprehensively study large co…
Semantics-guided Skeletonization of Sweet Cherry Trees for Robotic Pruning
Alexander You, Cindy Grimm, Abhisesh Silwal +1
Dormant pruning for fresh market fruit trees is a relatively unexplored application of agricultural robotics for which few end-to-end systems exist. One of the biggest challenges i…
A Robust Illumination-Invariant Camera System for Agricultural Applications
Abhisesh Silwal, Tanvir Parhar, Francisco Yandun +1
Object detection and semantic segmentation are two of the most widely adopted deep learning algorithms in agricultural applications. One of the major sources of variability in imag…
