Details of arrow-shooting boy karakuri mechanism

This video (in Japanese) explores the right arm mechanism for the famous arrow-shooting boy karakuri. This is a sophisticated automaton that can pick up arrows, put them on a bow string, pull the bow, and fire it at a target. There are additional motions to make the figure come to life. The animation shows the three cams that control the arm's three axes of motion.
