Mechanical automaton

‍

This mechanical automaton is moved by a crank. There are four cams which are circular disks that move up and down as the crank rotates. The followers of the cams are the tubes which have a nail-like appearance with a flat circular top. The entire structure is enclosed in a rectangular arch-way. The automaton is placed on a flatbed to keep it elevated and secure when placed on any flat surface.
