Design and Function Evaluation of Line Follower Plant Sprayer Robot

Agriculture tools are necessary for increasing food security in Indonesia. Automatic spraying for plants became one of the tools that help in pot plant maintenance. This study was developing a prototype of an automatic line follower robot for spraying plants. Designing a new construction and adding a line follower sensor, this robot could move between plant pots with the guidance of a black line. The main chassis of this robot is made from a 3 mm aluminum plate with a 50 cm length and 20 cm width. Control of this robot using Arduino Uno as a microcontroller that could control the movement of the robot and also could control the movement of the nozzle and flow rate. Performance testing of this robot was held inside the room with a concrete floor and placed on the white fabric with a black line as a guide and sign to stop and spray. As the result, the average linear speed for this robot was 0,7 m/s and the flow rate for spraying was 8,9 ml/s with 89,5% accuracy.
