This paper presents a high-speed cinephotogrammetry combined with a digital image processing experimental technique which studies the entire motion of the linkage connected to a gear reduction and a DC motor. The light-weight reflectors placed on a flexible four-bar linkage are monitored by a high-speed camera. The film is then digitized and the entire motion affected by the whole system is analyzed.
