  • 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: 20250125044
    Abstract: A caregiving robot and a caregiving system and method employing the same are provided. The caregiving robot includes a movement module, an interaction module and a control module. The interaction module receives an input instruction from the caregiver, and the input instruction includes an identity information and a target location information of the care recipient and a caregiving task information. During execution of the caregiving task, the control module controls the movement module to make the caregiving robot move to a target location according to the target location information. When the caregiving robot arrives at the target location, the control module controls the interaction module to interact with the care recipient according to the caregiving task information so as to collect health status input from the care recipient, and generates a status report accordingly. The status report includes health status information and status evaluation information of the care recipient.
