    Abstract: Disclosed herein are a method of localization using multi sensors and a robot implementing the same, the method including sensing a distance between an object placed outside of a robot and the robot and generating a first LiDAR frame by a LiDAR sensor of the robot while a moving unit moves the robot, capturing an image of an object placed outside of the robot and generating a first visual frame by a camera sensor of the robot, and comparing a LiDAR frame stored in a map storage of the robot with the first LiDAR frame, comparing a visual frame registered in a frame node of a pose graph with the first visual frame, determining accuracy of comparison's results of the first LiDAR frame, and calculating a current position of the robot by a controller.

    Abstract: Disclosed herein are a method of acquiring an image for recognizing a position and a robot implementing the same. In the method and robot, information value concerning movement of the robot is measured to efficiently acquire images including overlapped areas, and lenses of cameras on both sides of the robot are slided in a direction opposite to a direction of movement of the robot based on the measured information value concerning movement.

    IPC: B25J9/16

    Abstract: A robot according to one embodiment may include a storage configured to store a map of a space in which the robot operates, an input interface configured to obtain at least one image of a surrounding environment of the robot, and at least one processor configured to estimate a first position of the robot based on the at least one image obtained by the input interface, determine candidate nodes in the map of the space based on the first position of the robot, and estimate at least one of a second position of the robot or a pose of the robot based on the determined candidate nodes. In a 5G environment connected for the Internet of Things, embodiments may be implemented by executing an artificial intelligence algorithm and/or machine learning algorithm.
