1-20. (canceled)

An autonomous mobile device that executes a task upon autonomously moving to a destination, comprising:

a known information storage device that stores information on known obstacles;
a peripheral information acquisition device that acquires peripheral obstacle information;
an identification device that identifies information on an unknown obstacle that is different from the known obstacles stored in the known information storage device, from the peripheral obstacle information acquired by the peripheral information acquisition device;
an assessment information acquisition device that acquires assessment information related to the unknown obstacle when the information on the unknown obstacle is identified by the identification device;
a scenario storage device that stores a plurality of action scenarios including an action scenario which is defined to execute the task and is other than an action scenario to cancel or continue the execution of the task;
and
a selection device that selects one action scenario among the plurality of action scenarios stored in the scenario storage device based on the assessment information acquired by the assessment information acquisition device;
wherein
the task is executed after the autonomous mobile device reaches a pre-registered via point on a travel path to the destination.
