Robot device and behavoir control method for robot device

Abstract

A robot apparatus causes the emotion in a feeling part (130) to be changed based on the information acquired by a perception part (120) to manifest the behavior of information acquisition as autonomous behavior. The robot apparatus includes a behavior control part for causing the robot apparatus to manifest a language acquisition behavior and a meaning acquisition part. The robot apparatus also includes a control part for performing the behavior control of pointing its object of learning. The robot apparatus causes changes in internal states, which are ascribable to the object, to be stored in a memory part in association with the object.

Description

[0001] This application is a divisional application of the invention patent application "robot device and its behavior control method" filed on October 11, 2001 with application number 01804288.0. technical field [0002] The present invention relates to robotic devices and methods of controlling their behavior. Background technique [0003] In recent years, robotic devices that take the appearance of animals, such as dogs, are appearing on the market. This robotic device responds to external information or its own internal state, such as its sensory state, and behaves like an animal. Among these robots, there is one that can perform behaviors such as kicking a ball, and there is also one that provides a learning function for it. Among these learning functions, one is a speech learning function. [0004] An ultimate goal in pet-like robotics is to generate realistic robotic devices, or in other words, to construct a scalable system. [0005] Attempts have been made so far...

Problems solved by technology

[0006] However, when assembling these functions, the conventional practice has been to change the probability of producing a state machine with a fixed set probability for behavior, or to replace the state machine entirely

[0007] Although the frequency of behavior changes through interaction with the user or the outside world, thereby increasing the complexity suitable for robotic devices, it cannot be said that such complexity is beyond the behavior originally presupposed by the designer (programmer) or outside the scope of the reaction

Similarly, the objects that a robot can recognize are limited so that the robotic device cannot recognize objects other than those specified by the programmer

This means that current robotic devices lack the ability to determine how to respond to unknown stimuli
