  1. Moving Toys This term we are going to focus on one particular mechanism... ...cams

  2. Best described as an odd shaped wheel Used to convert rotary motion into linear motion As the cam rotates then the follower follows the shape (profile) of the cam Different shaped cams will cause the follower to move up and down in a different way. What is a cam?

  3. A simple cam mechanism consists of... Cam follower – Follows the outline (profile) of the cam wheel, moving up and down as a result Wheel or Cam – Remains in a fixed position. Turns causing the toy to move up and down as required Axle – Supports and turns the cam wheel Crank Handle – Operates the mechanism by turning the axle and cam wheel Frame - Holds the mechanism in place and provides stability

  4. What could you make? Think about the movement Now onto some design ideas...

  5. What will it look like? How will it work? Think about different possibilities What will you use to make it? Detailed, annotated (labelled) drawing... of the front (what you will see)and the back (what you won’t see!) Your design
