Analytical Review on Developing Progress of the Quadruped Robot Industry and Gaits Research

The rapid development of artificial intelligence technology has changed the quadruped robots' controlling system of gait from a traditional way into intelligent monitoring. At the beginning of this paper, analysis is conducted on several prominent robots developed by international groups. The gait research of quadruped robots includes an investigation of gait features and a comparison between different gait types, along with the analyses of the characteristics and the rationals behind different gaits in various applications. Hence, this paper summarised the progress of quadruped robots in gait research and the prospects are concluded to give ideas on how the future gait research on quadruped robots would proceed.
