Abstract
Background: At present, China's logistics industry is trying to change from laborintensive to technology-intensive, from the traditional model to modernization, intelligent upgrade, accompanied by the application and popularization of various advanced technologies and equipment. Nowadays, intelligent robots with functions such as handling, stacking, and sorting have become a hot topic in the logistics industry. To solve the problem of labor costs increase the logistics demand of logistics, improve the efficiency of processing of materials, the authors have designed main STM32F427 microcontroller chip, with smooth, round of omnidirectional mobile platform of vehicle chassis, external collision distance sensor, gyroscope and infrared sensors, temporary storage, and transportation of goods such as multi-functional integrated logistics robot.
Methods: According to the actual application requirements, the mechanical structure of the logistics robot, the hardware, and the software of the control system is designed.
Results: The experimental results show that the transportation and storage of materials in specific sites are well realized. The grasping and releasing accuracy and the positioning accuracy of the robot are relatively reliable. The study of the behavior of average tracking accuracy and average obstacle avoiding capability is the major contribution in this paper.
Conclusion: The experimental results fully prove that the robot designed in this paper has many functions, high intelligence, and strong practicability.
Keywords: STM32, logistics robot, control system, positioning, RoboCup, hardware control design, short-circuit protection circuit.
