Greyhounds can run very fast with their galloping gait mechanics. The galloping gait of the greyhound is remarkable for gait efficiency among quadrupedal as it is believed that the biomechanical structure supporting the mass is decoupled from the locomotive structure. With the help of rotatory galloping, a greyhound achieves the double suspension gait which is the fastest gait but also exhausting one. In this study, using a high frame rates camera with 250 - 500 frames per second motion images of the greyhound rotatory gallop mechanism were captured in slow motion in the straight run chase for studying the rotatory galloping mechanism and features. By carefully setting up a video image tracking software and a frame of reference, the greyhound galloping gait paws motion was analysed for relative displacement, speed and acceleration to infer kinetic energy in the gait. Likewise, using the manual and auto-tracking functions of the software, the galloping-related relative position of the hard points was analysed for pose and gait study. The motion tracking study of the greyhound galloping mechanism allowed a better understanding of the greyhound galloping mechanism and also the underlying functions and characteristics of greyhound rotatory galloping. Through the study, it is also shown that the contribution of different elements of rotatory galloping for greyhound locomotion. This study could give future directions to efficient robot locomotion and injury prevention mechanisms for fast runners.
