Development of Delivery Robot (DELIBOT) Using Microcontroller and Line Tracker

Abstract

The project was developed to transport items using an Automated Guided Vehicle (AGV) delivery robot named “Delibot”. For this project, the robot was used in a restaurant environment to transport food and dishes. The robot was able to move inside the workplace by following the black track that guides the robot to reach different locations from the kitchen to customers’ tables and return to the kitchen. The robot movements were controlled and guided by a microcontroller (ATMega2560) and proximity sensors. Four proximity sensors were installed for detecting the tracks and junction nodes. The robot can be programmed by the user to move and follow directions from origin to its destination. The robot was driven by 4 DC motors that allow it to move straight, turn left or right and rotate from its current position. To make the robot user-friendly, it was equipped with an audio module player that allows speaking like humans to communicate to the user.

The robot was tested using a small-scale prototype and successfully achieved the objective of transporting item and its capability to be reprogrammed according to the robot’s track path
