  • Publication number: 20250123631
    Abstract: An autonomous mobile robot and an operating method thereof are provided. The autonomous mobile robot includes a movement module, a detection module, a control module and an interaction module. The control module includes a determination unit and a navigation unit. The determination unit determines whether there is an obstacle near or on a predetermined path of the autonomous mobile robot according to the environment information. When the obstacle is on the predetermined path, the navigation unit decides an obstacle avoidance strategy according to the environment information and the type of the obstacle. The obstacle avoidance strategy at least includes moving along a side path, stopping aside to yield, moving backward and stopping at a yielding point to yield, and detouring. When the obstacle is near or on the predetermined path, the interaction module performs an interaction action according to the obstacle avoidance strategy and the type of the obstacle.

  • Publication number: 20240319743
    Abstract: A system and a method for an autonomous mobile robot to ride and co-share an elevator with human(s) are disclosure. The core software modules and method proposed include a human detection and localization module, a human identification and state estimation module, a human-robot-interaction module, and an elevator confined space positioning module. Upon an elevator riding task is started, the human detection and localization module and the human identification and state estimation module detect and count the at least one human inside and/or outside the elevator, and the human-robot-interaction module interacts with the at least one human. The elevator confined space positioning module carries out a space positioning inside the elevator according to a result of detecting and counting the at least one human through the human detection and localization module and the human identification and state estimation module, and chooses to enter the elevator or restart another elevator riding task.

  • Publication number: 20230004170
    Abstract: A modular control system for controlling an AGV includes an interface, a processor, a memory, and a plurality of programs. The plurality of programs include a task scheduling module, a sensor fusion module, a mapping module, and a localization module. The interface receives a command signal from an AGV management system and sensor signals from a plurality of sensors. The memory stores a surrounding map and the plurality of programs to be executed by the processor. The task scheduling module converts the command signal to generate an enabling signal. The sensor fusion module processes the received sensor signals according to the enabling signal and generates an organized sensor data. The mapping module processes the organized sensor data and the surrounding map to generate an updated surrounding map. The localization module processes the organized sensor data and the updated surrounding map to generate a location and pose signal.
