Book checking robot capable of accurately controlling motion trail

Abstract

A book checking robot capable of accurately controlling a motion trail comprises a robot chassis, a checking frame is fixedly installed above the robot chassis, a first laser distance measuring sensor is fixedly installed on the front side surface of the robot chassis, and a second laser distance measuring sensor is fixedly installed on the rear side surface of the robot chassis. An SLAM laser radar is fixedly installed above the robot chassis, the signal output ends of the first laser distance measuring sensor, the second laser distance measuring sensor and the SLAM laser radar are all in signal connection with a central control system, the central control system is fixedly installed in the robot chassis, and driving rollers are arranged below the robot chassis. A driving device for driving the rollers is in signal connection with the central control system. The method overcomes the defects in the prior art, and has the advantages of higher control precision, higher scene adaptability and the like. The book recognition accuracy of the book checking robot can be effectively improved, and the scene adaptability of the book checking robot to different libraries can be improved.

Description

technical field [0001] The invention relates to the technical field of book inventory equipment, in particular to a book inventory robot that can precisely control a motion trajectory. Background technique [0002] There are two main methods for controlling the motion trajectory of the book inventory robot: one is to paste a black trajectory guide bar on the ground of the library, and use the infrared sensor at the bottom of the book inventory robot to guide the book inventory robot to follow the trajectory. This method requires A lot of black track guide bars are pasted on the ground of the library. The construction is troublesome when the project is implemented, and the track guide bars are difficult to maintain for a long time and require regular maintenance and update. The other is to use SLAMSLAM lidar navigation to guide the book inventory robot to walk along the planned path. This method does not require additional construction of the library during project implementa...

Problems solved by technology

[0002] There are two main methods for controlling the motion trajectory of the book inventory robot: one is to paste a black trajectory guide strip on the floor of the library, and use the infrared sensor at the bottom of the book inventory robot to guide the book inventory robot to follow the trajectory. A lot of black trajectory guide strips are pasted on the ground of the library. The construction is troublesome when the project is implemented, and the trajectory guide strips are difficult to maintain for a long time, and regular maintenance and updates are required.

The other is to use SLAMSLAM lidar navigation to guide the book inventory robot to walk along the planned path. This method does not require additional construction of the library during project implementation, but because the navigation accuracy of SLAMSLAM lidar will be about 10cm This will lead to an error of about 10cm in the distance between the book inventory robot and the bookshelf when the book inventory robot performs book inventory, which will make it difficult to improve the book recognition rate of the book inventory robot
