System and method for autonomous mobile robot to ride and co-share elevator with human(s)

A method for an autonomous mobile robot to ride and co-share an elevator with humans, comprising steps of:

• (a) navigating an autonomous mobile robot to an elevator lobby, and detecting and locating at least one human relative to the autonomous mobile robot, and identifying and estimating a state of the at least one human by the autonomous mobile robot;
• (b) pressing a button on a call panel by the autonomous mobile robot so as to start an elevator riding task;
• (c) detecting whether the elevator is in a door-open state or a door-close state by the autonomous mobile robot;
• (d) detecting the at least one human inside and outside the elevator, and counting the at least one human by the autonomous mobile robot in response to the elevator is in the door-open state;
• and
• (e) carrying out a space positioning inside the elevator according to a result of detecting and counting the at least one human by the autonomous mobile robot, wherein the autonomous mobile robot performs an elevator occupancy state estimation to identify an available position with at least one traversable path, and chooses to enter the elevator or restart another elevator riding task,
• wherein the step (e) further comprises determining an elevator floor panel to use by the autonomous mobile robot and determining an optimal position to wait in the elevator with considerations of at least the elevator occupancy state and the elevator floor panel to use.
