Two-dimensional code positioning-based intelligent warehousing mobile robot system

Abstract

The invention comprises an intelligent warehousing mobile robot system. The intelligent warehousing mobile robot system comprises a mobile phone client, a robot module and a server, wherein the mobile client, the server and the robot module communicate with one another through a wireless communication network; the robot module comprises an ARM chip, an arduino chip, a camera, a motor driving module and a robot body; the server carries out path planning through adopting an A*path planning algorithm so as to obtain paths only containing inflection point coordinates and sends the paths to the robot module, so that control and direction correction of the robot module can be realized; the robot module carries out internal positioning through using a gyroscope and a mileage meter, and at the same time, the camera scans a two-dimensional code on the ground of a warehouse, so that the external positioning of the robot module can be carried out through using the arrangement scheme of the two-dimensional code of the warehouse, and therefore, the correction of the internal positioning can be realized. With the intelligent warehousing mobile robot system of the invention adopted, the accumulated error of the internal positioning can be effectively eliminated, accurate positioning can be obtained, and therefore, the robot can reach a destination more accurately to prepare for cargo transport.

Description

technical field [0001] The invention belongs to the technical field of intelligent storage control, and in particular relates to an intelligent storage mobile robot system. Background technique [0002] With the rapid development of e-commerce, the modern logistics warehousing system has the characteristics of huge warehouse scale, various types of inventory, and extremely high requirements for short delivery time and low operating costs. If the traditional manual operation method is adopted, it is obviously unable to meet the above requirements. Requirements, the use of warehouse robots to replace manual work within the warehouse system has become a feasible method, and its prospects are very promising. Since the 21st century, robot technology has been considered as one of the high technologies that are of great significance to the development of emerging industries in the future, and domestic and foreign industrial circles have high hopes for robot technology to lead the f...

Problems solved by technology

This solution first needs to carry out various complex planning and layout when building the warehouse. The construction cost is high, the power consumption is large during use, and the system robustness is low. It is easy to paralyze the entire warehouse system due to problems with some components, and the maintenance cost is high. , the flexibility of automation is low, only automatic transportation is realized, the efficiency is low, and it is not suitable for the characteristics of various types and large batches of modern e-commerce warehouses. It is mainly used in some fixed production lines and other places.

[0005] The scheme based on the automatic navigation vehicle: at present, there are many schemes, which are equipped with automatic guidance devices such as electromagnetic or optical. At the same time, because the electromagnetic or optical devices are easily polluted by the environment, the automatic guided vehicle will be paralyzed due to yaw and no automatic correction ability. Since it can only walk according to the predetermined route, the path planning is relatively simple, but it is generally difficult to be the optimal for the entire warehouse. routing, so inflexible and less efficient in busy warehouses

[0006] Robot-based solution: This is a solution with high flexibility, but due to the small effective range of activities, it does not use a large-scale warehouse. Generally, it is only due to small-scale cargo sorting and handling.
