Real-Time Kinematic Imagery-Based Automated Levelness Assessment System for Land Leveling Open
Many cropping systems, notably for rice or soybean production, rely largely on arable land levelness. In this study, an automated levelness assessment system (ALAS) for evaluating lowland levelness is proposed. The measurement accuracy of …

Performance Evaluation of a Typical Low-Cost Multi-Frequency Multi-GNSS Device for Positioning and Navigation in Agriculture—Part 2: Dynamic Testing Open
Dynamic performance of a GNSS (Global Navigation Satellite System) positioning device (PD) is of interest to end users of satellite-based auto-guidance systems (AGS) for agricultural vehicles, especially when a low-cost PD is used. This st…

Positioning Control of a Mobile Manipulator using Image Feature Open
This manuscript reports on a vision-based autonomous grain unloading system for a head-feeding combine robot. In order to perform harvesting fully autonomously, the combine robot is also required to autonomously unload the harvested grain …
