  • Publication number: 20230185307
    Abstract: An embodiment device for planning a path of a robot includes a camera configured to capture an image in a moving direction of the robot and a controller configured to detect a moving obstacle in the image in the moving direction of the robot, to calculate a speed and a moving direction of the moving obstacle based on a change in a location of the moving obstacle, and to set a region of the moving obstacle based on the speed and the moving direction of the moving obstacle, the region being in a form of an ellipse.

  • Publication number: 20220334589
    Abstract: A map generating system for autonomous movement of a robot includes a three-dimensional (3D) point cloud map input device, a 3D point cloud map regeneration device that extracts only 3D point cloud data corresponding to an arbitrary reference height from the 3D point cloud map to regenerate the 3D point cloud map, an unoccupied area generation device that extracts ground point cloud data from the 3D point cloud map to set an unoccupied area into which the robot is able to move, an occupied area generation device that extracts obstacle point cloud data from the 3D point cloud map to set an occupied area into which the robot is unable to move, and a two-dimensional (2D) map generation device that adds the unoccupied area and the occupied area to an area on the 3D point cloud map to generate a 2D map.

  • Publication number: 20220276654
    Abstract: An apparatus for generating multiple paths for a mobile robot includes a multi-path generation module that detects “n” multiple waypoints located at a maximum straight line distance without collision with an obstacle in a space within a predetermined radius in “n” directions centered on the mobile robot, and plans “n” multiple paths to a destination by passing through each of the multiple waypoints as an initial waypoint, and an optimal path selection module that selects a path satisfying a preset cost function requirement among the “n” multiple paths, which are planned, as an optimal path, making it possible to select the optimal path suitable for various driving situations of the mobile robot by simultaneously generating multiple paths along which the mobile robot is to travel from its current location to its destination.

  • Patent number: 10262532
    Abstract: A method of providing forward traffic light information during a stop includes capturing a front image in a vehicle, detecting traffic light information from the front image, and outputting a notification corresponding to the traffic light information to a mobile terminal or the vehicle depending on at least one of a communication state with the mobile terminal and a monitor state of the mobile terminal. A system for providing forward traffic light information during a stop includes a mobile terminal, and a vehicle that captures a front image and to detect traffic light information from the front image, where a notification corresponding to the traffic light information is output to the mobile terminal or the vehicle depending on at least one of a communication state with the mobile terminal and a monitor state of the mobile terminal.
