Abstract—Nowadays, automatic factory is the goal pursued by many industries. Therefore, transporting need is becoming more and more important. Using a mobile robot to transport between stations will substitute human to increase productivity. In this paper, an omnidirectional mobile robot has been established by aluminum extrusion and acrylic. Digital Signal Processor (DSP) is a main controller that commands the robot to move and transport. Visual identification is realized via a camera using a Single Board Computer (SBC) in a specified area and gets command to perform the task. Finally, the mobile robot can complete the related tasks autonomously. Furthermore, the modularizing robot can be easy to change the operating mode to perform various tasks conveniently.
