  • Patent number: 9207676
    Abstract: A system for guiding an automated guided vehicle (AGV) is provided. The system includes a guidance path, an AGV, an image capturing apparatus and an operation unit. The guidance path guides the AGV. The AGV moves on the guidance path and is guided by the guidance path. The AGV moves in a vision guidance region after departing from the guidance path. The image capturing apparatus captures a vision guidance region associated image. The vision guidance region associated image at least includes an image of the vision guidance region. The operation unit determines whether the AGV departs from the guidance path, and calculates position information of the AGV in the vision guidance region. When the AGV departs from the guidance path, the operation unit guides the AGV according to the vision guidance region associated image.

  • Patent number: 7643906
    Abstract: An obstacle and cliff avoiding system is disclosed, which is substantially a movable chassis having at least a displacement sensor arranged thereon. In a preferred embodiment, each displacement sensor is tilted by a specific angle with respect to a surface detected thereby while being driven to move in circle by a rotating apparatus for enabling the same to scan a defined fan-like area or the circular area around the chassis in a circulating manner. As each displacement sensor is tilted by the specific angle and is initiated to issue a working signal, the paths of signal emission and reception of each sensor are defined by the specific angle, whereas the reflected working signal received by the sensor is sent to a control unit to be compared with the working signal so that the control unit is able to evaluate whether there is an obstacle or a drop in front of the moving direction of the movable chassis and thus control the chassis to maneuver around the obstacle or the drop.
