Autonomous behavior robot that performs welcoming behavior

摘要

The present invention evokes rapport with a robot by emulation of human-like/animal-like behavior. A robot (100) is provided with a movement-assessing unit for determining movement direction, a behavior-assessing unit for selecting an action from multiple kinds of actions, and a drive mechanism for executing a designated movement and action. When a user enters an entryway, a previously set external sensor detects the homecoming and notifies the robot (100) of the user's homecoming via a server. The robot (100) goes to the entryway and welcomes the user home by performing an action that shows good will such as sitting down and raising a hand.
