It was designed to be able to move with any of the possible gaits. The project was not successful because the horse was very heavy and the available motors at the time could not move it fast enough to get dynamic stability. So in the end all it could do was walk slowly with only one leg off the ground at a time. Sometime it’s not the computer side that prevents advances in robotics.<div><br></div><div>Ed<br><div>
