AI Technical Summary

Technical Problem

Existing automated guided vehicles (AGVs) face challenges in reliably connecting to towed objects due to unstable recognition of markers by the vehicle's camera.

Method used

The AGV is equipped with a camera positioned at a horizontal central axis and a connecting unit that includes guide rollers and a contact roller to stabilize marker recognition, ensuring precise alignment and secure connection with the towed object.

Benefits of technology

This configuration enhances the reliability of the connection between the AGV and the towed object by maintaining stable marker recognition and correcting positional deviations, ensuring a secure and stable coupling process.

Abstract

To provide an unmanned carrier with improved reliability in coupling the unmanned carrier with a towed object by stabilizing the recognition of a marker of the towed object by a camera of the unmanned carrier.SOLUTION: An unmanned carrier 10 tows a towed object 12 having a connectable connected part 17 and a marker 19 for position recognition. An unmanned carrier body 21 of the unmanned carrier 10 travels on a traveling surface 11. A connection unit 22 is protruded outward from the unmanned carrier body 21 and is detachably connected to the connected part 17 of the towed object 12. A camera 23 has a central axis 56 of the field of view, which is made in a horizontal direction, and is arranged at a height where the marker 19 is positioned on the central axis 56 of the field of view to recognize the marker 19. A marker processing unit estimates a relative positional relation between the unmanned carrier body 21 and the towed object 12 from the marker 19 recognized by the camera 23.SELECTED DRAWING: Figure 1
