A Mobile Application Development For Programming With Blockly to Control Line Follower Robot

Abstract

            The objectives of this research were 1) to design and develop a programming application with a mobile visual block for controlling a small line-following robot, 2) to evaluate the application's efficiency, and 3) to study the satisfaction of using the application. The target groups were 3 experts and 50 youths participating in the Science Week event. Research tools were: 1) visual block programming application via mobile phone and small line follower robots; 2) application efficiency assessment form; and 3) application satisfaction assessment form. The statistics used in the research were percentage, mean, and standard deviation.

            The results of the research were as follows: 1) design and development of a programming application with a mobile visual block for controlling a small line follower robot. It was found that the application had two functional components, including the programming application part with visual blocks and the line follower robot. The application was developed in JAVA under the Android Studio development environment, and the line follower robot consists of 3D-printed robotic structure hardware and operating electronics such as servos, motors, wheels, control circuits, connection expansion boards, and Bluetooth devices. 2) Application performance evaluation results from experts, it was found that the system has 100 percent accuracy, and 3) the study results of satisfaction with using the application were found to be at the highest level.
