a mechanical toy that uses a cam mechanism to animate a character or scene - plural-automata

a bar that follows the movement of the cam disc

a device that holds the follower in position

Cams in a product

Design and technology

Cam mechanisms

Wood functional properties

Develop ideas through cross-section diagrams

Wood construction and joining techniques

Make an accurate box frame

Assemble cam mechanisms

Test and adapt cam mechanisms

This unit develops pupils' knowledge of mechanisms through cams. Pupils will develop knowledge of the properties of wood and apply this by selecting suitable materials for functionality. Knowledge of wood construction and joining techniques are introduced and applied through making an automaton.

Cams: automata

Physical activity and equipment requiring safe use

Use of equipment that may require supervision for safety, e.g. scissors in KS1, needles, paint, knives, cooking.

In a cam mechanism, what are the cam discs fixed to?

Which parts of a cam mechanism are affected by changing the size or shape of a cam?

Which of these materials could be used to make an axle?

Which part of a cam mechanism on a prototype automaton is shown in this image?

Order the parts of a cam mechanism to show the order in which they are affected by the input movement.

Which part of a cam mechanism is indicated in this diagram?

Which words can be used to describe the output movement of a cam mechanism?

Which part of a cam mechanism supports the follower, keeping it in place?

Why does a cam disc need to fit tightly to the axle?

Which of these products has a cam mechanism?
