Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] combine Figure 1~Figure 3 , a method for express storage based on a mobile robot according to the present invention, the mobile robot is provided with a camera 1, a manipulator 2, a lifting platform 3, a laser radar 4, a binocular camera 5, and the manipulator 2 is used to grab the express , the lifting platform 3 adjusts the height of the manipulator 2 according to the number of layers of the shelf after the mobile robot moves to the position of the shelf, so that the manipulator can grab the express delivery to the target shelf. The binocular camera 5 is used to capture the image information of the environment in real time, and the laser radar 4 It is used to scan point cloud information, and camera 1 is used to scan the courier number; the specific steps of the method are as follows:

[0025] Step 1. Establish a database including courier informat...

Abstract

The invention discloses an express warehousing method based on a mobile robot, and the method specifically comprises the steps: enabling the mobile robot to determine an unoccupied goods shelf and the position of the unoccupied goods shelf according to the database information of a warehouse, building and optimizing a grid semantic map through a sensor fusion method, and carrying out path planning according to the optimized final grid map and the position of the goods shelf, and controlling the robot to convey the express to the corresponding shelf, scanning the express number through the camera, then notifying the pickup person of the express warehousing information and updating the warehouse database, and updating the database again after the user picks up the express. According to the method, the grid semantic map is obtained through an information fusion method, and the map is optimized through semantic information, so that the mobile robot can accurately identify the position of the goods shelf in the courier station to perform path planning.

Description

technical field [0001] The invention belongs to express logistics technology, in particular to a mobile robot-based express delivery storage method. Background technique [0002] At present, with the rapid development of e-commerce, express delivery is an indispensable part of logistics distribution. In the current logistics distribution service station, the courier staff usually send the courier to the receiving shelf and print out the shelf number, and then integrate the shelf number with the recipient information and send it to the recipient. In view of the variety of express delivery, the entire work Using a lot of manpower and material resources. [0003] At present, there are already some forms of unmanned post stations, such as smart containers, using AVG cars, etc. The above methods have the following disadvantages: For smart containers, when the express delivery volume surges in special time periods of the year, it is necessary to increase the capacity of the smart...
