In view of the common logistics robot and vehicle is difficult to adapt to the complex and changeable requirements of modern logistics environment, the respective advantages of omni-directional mobile mechanism and robotic arm used in the traditional logistics are combined to design and develop an omni-directional mobile automatic guided logistics platform with a robotic arm. In this research, detailed structure of omni-directional mobile mechanism and the robotic arm for the platform is designed. Software and hardware of federated control system for the operation of omni-directional movement, automatic guiding and action of robotic arm in the platform are built with the PLC and touch screen as the core. Subsequently, the system control logic was explained and the physical prototype was developed. Finally, an experimental study was carried out in logistics engineering laboratory of Beijing Institute of Graphic Communication (BIGC). The research improved the flexibility of logistics transmission equipment, increase the operational efficiency of logistics system and intelligent degree. It has a certain value for the related research for the application field of the mobile robot and logistics equipment field.
