Mobile Robot for Environmental Measurement in Greenhouse

Abstract

The environmental information in a greenhouse is one of the essential items in precision agriculture for improving the productivity of crops. In many cases of environmental measurement in a greenhouse, a fixed sensor can take measurements near the installation location. However, to estimate the distribution of environmental information in the entire greenhouse, it is necessary to install many sensors, which increases the cost. Therefore, in this study, to acquire more detailed environmental information, we propose a system to measure the environmental information in a greenhouse by using a mobile robot with Robot Operating System (ROS). The proposed mobile robot consists of a CO 2 sensor, temperature sensor, humidity sensor, and Laser Range Finder (LRF) for environmental sensing. In this paper, we confirmed the usefulness of the proposed system from a verification experiment using a prototype mobile robot..
