e-Learning Lesson 1 by Tan Hao Ming (18)

1a) I used cams as the mechanism as cams will keep rotating as the wheels rotate (they are jointed together), and when the cams rotate, it will cause the body of the toy to move

     up and down (oscillating movement) continuously, together with the wheels. I also attach the link or joint which joins the cam together with the wheels in the 'hole' of the wheel.
