In this project we made our own toy. But we had an allianc partner incase we needed some help we go with our partner first instead of the teacher. This project was about knowing what simple machines are, cams, how to use tools etc. We made a toy that required to have at least one of the followings , cams, follower, rotary motion and reciprocating motion. My toy has a centric and a circular cam. There is two types of cams, the follower and the cam profile. The follower is the handle you move. The follower moves the axle. That's what we were suppose to do in our project. It wasn't easy it was a very challenging project. What I though was most difficult about this project was coming up with the idea. You were suppose to think of any character and make it make a movement in your toy. But over all I really enjoyed it.
