Abstract
A Field Server, wireless sensor network system for agriculture, provides useful and practical monitoring in a crop field. To achieve more advanced and smarter sensing, we have proposed a robotic Field Server monitoring target data widely and closely in a crop field. The robotic Field Server consists of a conventional Field Server with sensors and wireless module for smart monitoring, a locomotion unit for moving in target fields, and a handling actuator unit for flexibly measuring the targets. The robotic Field Server supported by fixed-type Field Servers is controlled at a remote site via the Internet. We conducted an experiment to collect detailed data of many target fruits in a pear orchard with the robotic Field Server moving around the field, and clarified the potential and effectiveness of the proposed monitoring system.
