Developing a quadrupedal robot with speech recognition movement control

摘要

The objective of this project is to develop a Quadrupedal (four legs) robot with speech recognition to control the movement. There are only three words of command to be recognized, which are “forward”, “backward”, and “left” command. Fourbar linkage is used as the basic mechanism for the robot's legs and comparison of sum of absolute error is used on the speech signal spectrum taken from its short time fourier transform.
