I tech we built automatons. The first thing that we did was we looked at some other automatons and tried to figure out how they worked. After we cut out our cardboard for the box, we assembled it. After the box was assembled we cut out our cam and followers. After that all we had to do was put it all together. For my automaton I had a hot air ballon has was going up and down. In my hot air ballon I had solder men.
