摘要:
A behavior decision system (70) includes a perceptual information acquisition unit (90) which acquires a cause factor being external or internal information acquired by a CCD camera (20), distance sensor (22), microphone (23) or the like and which influences a behavior and a motivational information acquisition unit (81) which acquires an occurrence tendency of a behavior influenced by the cause factor based on the cause factor from the perceptual information acquisition unit (90), a behavior selecting processor (82) which compares occurrence tendencies corresponding to two or more behaviors, acquired by the perceptual information acquisition unit (90) and motivational information acquisition unit (81) and belonging to the same group, to thereby select one of the behaviors, and an output semantics converter module (68) which controls moving parts based on the behavior selected by the behavior selecting processor (82) for expressing the selected behavior. With the behavior decision system, there can be provided a robot having an improved likeness to a living thing or a creature and showing a more similar behavior to that of an animal.
摘要:
An arithmetic processing device for inter-object data communication has an object manager for connecting objects so as to enable exchange of data between the objects, and a connection data supplying unit for supplying the object manager with connection data necessary for achieving the connection between the objects. An inter-object communication method and a robot incorporating the arithmetic processing device are also provided. The robot may be designed to enable a user to replace parts thereof, thus changing the robot configuration. The robot preferably includes a part detection unit for detecting parts attached to the robot, and outputting a part detection result in accordance with the detection. An information storage unit stores information corresponding to the part detection result for each configuration obtained by replacement of the parts. A software changing unit revises robot-controlling software in correspondence with a changed configuration, based on a comparison of the part detection result with the information stored in the information storage unit. A controller controls general robot operations in accordance with the revised software.
摘要:
A new scheme for fast realization of encryption, decryption and authentication which can overcome the problems of the RSA cryptosystem is disclosed. The encryption obtains a ciphertext C from a plaintext M according to C≡Me (mod n) using a first secret key given by N (≧2) prime numbers p1, p2, . . . , pN, a first public key n given by a product p1k1 p2k2 . . . pNkN where k1, k2, . . . , kN are arbitrary positive integers, a second public key e and a second secret key d which satisfy ed≡1 (mod L) where L is a least common multiple of p1−1, p2−1, . . . , pN−1. The decryption recovers the plaintext M by obtaining residues Mp1k1, Mp2k2, . . . , MpNkN modulo p1k1, p2k2, . . . , pNkN, respectively, of the plaintext M using a prescribed loop calculation with respect to the first secret key p1, p2, . . . , pN, and by applying the Chinese remainder theorem to the residues Mp1k1, Mp2k2, . . . , MpNkN. This encryption/decryption scheme can be utilized for realizing the authentication.
