Omnidirectional Mobile Robots Applied to Smart Warehouses

Abstract

The invention discloses an all-round mobile robot applied to an intelligent warehouse, including a mobile platform, a traction mechanism, an ultrasonic obstacle avoidance system, a vision module, a remote control maintenance module, and an auxiliary positioning mechanism matched with the mobile robot, so as to realize the robot with The traction mode transports the shelves to the target area automatically, and monitors the working status and storage environment of the robot; and the robot can be managed and maintained through the network; in addition, it is designed as a Mecanum wheeled mobile platform, which can move in all directions and has high flexibility.

Description

technical field [0001] The invention relates to the technical field of robot structure design and robot control, in particular to an omnidirectional mobile robot applied to an intelligent warehouse. Background technique [0002] The logistics management activities of intelligent warehouses are basically controlled by electronic computers, and the management of goods (raw materials, products, etc.) is equipped with robots. The number of employees is low and the operation efficiency is high. The omni-directional movement involved in the present invention refers to movement modes such as oblique walking and zero-radius turning in addition to translation in front, rear, left, and right directions. [0003] With the rapid development of the Internet of Things industry, in order to adapt to the times, various storage robots have appeared one after another at home and abroad. [0004] (1) In foreign countries, Amazon and others have established their own robot teams for warehouse ...

AI Technical Summary

Problems solved by technology

However, in order to use this warehouse automation system developed by Kiva Systems, it is necessary to carry out specialized transformation on the target warehouse and add a lot of necessary infrastructure. The cost is high, the technical difficulties are great, and the maintenance is difficult. It is not suitable for most domestic enterprises. the introduction of

[0005] (2) Domestically, there is no relatively complete warehouse management robot application

For most enterprises, many medium and large warehouses have not yet introduced intelligent robots or the imported robots have single functions and are not user-friendly; the way of goods distribution and packaging is still the traditional "manual distribution" mode instead Intelligent distribution, so the warehouse operation speed has not been broken for a long time

[0006] (3) The top logistics management companies in China have adopted the pure sensor technology of AGV, which has certain limitations; in addition, many AGV cars adopt a lifting structure, and the car needs to carry the overall mass of the shelf. The motor will cause a certain rigid impact, which will affect the service life of the trolley and increase the loss of energy

[0007] (4) For most AGV cars, when the cruising track is a curve, the wheels need to produce a differential speed to achieve the turn, and the required curve radius is large. When many cars are working in the warehouse, the activity of the car limited by space and time

[0008] (5) Existing warehousing robots only use electronic sensor positioning methods, which are subject to high environmental interference, low positioning accuracy, and prone to malfunctions during work

[0009] It can be seen that the above problems are difficult for the efficient operation of most warehouse management in China, and the positioning of the equipped robots is difficult, resulting in the phenomenon that the intelligent warehouse technology has not been broken through for a long time, which greatly limits the development of intelligent warehouses in many aspects, especially intelligent warehouses. development
