Abstract: A system determines one or more constraint locations that are present in an environment. A constraint location is a location in the environment through which a user, pet, or moving device is deemed likely to pass due to one or more physical constraints such as walls, furniture, and so forth. For example, a constraint location may be located at a midpoint of a doorway, or where a corridor narrows. Movement of an autonomous mobile device in an environment takes these constraint locations into consideration. In one implementation the autonomous mobile device is prevented from stopping within a threshold distance of a constraint location to avoid blocking movement of others.

Abstract: A robot that is able to move about an environment determines a wait location in the environment to wait at when not otherwise in use. The wait location may be selected based on various factors including position of objects, next scheduled use, previous usage of the robot, availability of wireless connectivity, user traffic patterns, user presence, visibility of the surrounding environment, and so forth. The robot moves to that location and maintains a pose at that location, such as orienting itself to allow onboard sensors a greatest possible view of the environment. If a wait location is occupied, the robot may move to another wait location.
