Navigation, Validation and Evaluation of Four-Wheeled Robot for Greenhouse Spraying

Abstract

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.

Equipment and Experiment of Greenhouse High-Pressure Atomization Spraying Based on PLC

“…Some scholars have designed a greenhouse automatic sprayer that advances and retreats along a rail laid between greenhouse crops (Alireza Rafiq et al, 2014). At present, some scholars have designed small spraying robots for greenhouse spraying that use sensors to detect plants and spray them (Hossein Mosalanejad et al, 2021).…”
