摘要:
The present invention relates to a robot and method for establishing a relationship between input commands and output reactions. When initiating an input configuration program, the robot fetches a predetermined motion output reaction and performs a corresponding motion. At this time, the robot receives a vocal input command from a user to obtain a vocal input profile, and establishes a relationship between the motion output reaction and the vocal input profile. When receiving the vocal input command again, the robot performs the corresponding motion according to the relationship. In addition, a sound assigned to the motion output reaction can be altered according to users' preferences. Accordingly, the motion output reaction may have different naming sound.
