Controlling the Line Follower Delivery Robot with MIT APP Inventor

Abstract

Abstract The Line follower robot is an autonomous robot that can detect and follow the line drawn on the floor using infrared sensor modules. Generally, the line follower robot detects a visible black line on the white surface. The delivery robot is an autonomous robot used for delivering items such as documents, foods, and the like. So, the line follower delivery robot is a robot that can deliver items and run on a path by detecting black line on white surface using infrared sensor. MIT App Inventor is a web service for creating mobile application for smartphones. It is easy for users who have little or have no previous programming experiences to create mobile applications using a visual block language. This paper presents controlling line follower delivery robot by using a smartphone. The researchers designed the line follower delivery robot and mobile application by using MIT App Inventor. The Bluetooth was used to connect between the smartphone and the microcontroller to control the line follower delivery robot. Manual and automatic control, speed performance of the robot’s delivery and load capacity are described in this paper.
