NAVIGATION, VALIDATION AND EVALUATION OF FOUR-WHEELED ROBOT FOR GREENHOUSE SPRAYING

摘要

This study investigates the potential of using a sprayer robot for the greenhouse with bell-pepper plants and compares its performance with the backpack sprayer. The infrared sensors were used to navigate the robot and the ultrasonic sensors were used to distinguish the beginning of each row for automatic spraying. Results showed that the robot's guidance was done well by the infrared sensor. It was capable for spraying plants on both sides of the greenhouse simultaneously with ultrasonic sensor. The sprayer robot had better spray quality and lower solution consumption and spraying time and spray loss than the backpack sprayer.
