  • Patent number: 11636612
    Abstract: An AGV navigation device is provided, which includes a RGB-D camera, a plurality of sensors and a processor. When an AGV moves along a target route having a plurality of paths, the RGB-D camera captures the depth and color image data of each path. The sensors (including an IMU and a rotary encoder) record the acceleration, the moving speed, the direction, the rotation angle and the moving distance of the AGV moving along each path. The processor generates training data according to the depth image data, the color image data, the accelerations, the moving speeds, the directions, the moving distances and the rotation angles, and inputs the training data into a machine learning model for deep learning in order to generate a training result. Therefore, the AGV navigation device can realize automatic navigation for AGVs without any positioning technology, so can reduce the cost of automatic navigation technologies.

  • Patent number: 11086330
    Abstract: A control system for an automatic guided vehicle includes a vehicle, a contour-detection module, a position-detection module, and a processing device. The contour-detection module is disposed on the vehicle. The contour-detection module is configured to detect a ceiling and a target object, which is disposed on the ceiling, and to generate a contour signal. The position-detection module is disposed on the vehicle. The position-detection module is configured to detect the position of the vehicle and generate a position signal. The processing device is configured to generate a target mark corresponding to the target object according to the contour signal and the position signal. The processing device is configured to automatically control the carrier to move along a movement path. When the contour-detection module detects the target object, the processing device corrects the movement direction of the vehicle according to the target mark.

  • Publication number: 20210191416
    Abstract: An automatic guided vehicle positioning system includes one or more positioning areas and an automatic guided vehicle. The positioning areas each have a positioning pattern. The automatic guided vehicle includes a beam emitter, a beam receiver, and a processor. The beam emitter is configured to emit a light beam to scan the positioning areas. The beam receiver is configured to be spaced apart from the beam emitter by a specific distance, wherein the beam receiver receives the light beam scattered by an area other than the corresponding positioning pattern of the positioning areas and does not receive the light beam retroreflected by the corresponding positioning pattern. The processor is configured to recognize the corresponding positioning pattern based on the light beam received by the beam receiver and the retroreflected light beam not received by the beam receiver and to position the automatic guided vehicle.

  • Patent number: 10755223
    Abstract: A logistic station includes a cabinet, a storage boxes in the cabinet, a volume measurement room, a volume measurement system, a user interface and a controller. The volume measurement room has a bottom plate and a ceiling. The volume measurement system in the volume measurement room measures the volume of a consignment. The volume measurement room includes a rangefinder and an image capturing device. The rangefinder on the ceiling measures the height of the consignment placed on the bottom plate. The image capturing device is disposed on the ceiling and captures an image toward the bottom plate. The user interface disposed in the cabinet displays information and receives shipping information and a shipping fee. The controller calculates the volume information according to the image and the height, calculates the shipping fee according to the volume information and the shipping information, and controls one of the storage boxes to open.
