Mechanical Systems

Design and make automata toys

Design

•Experimenting with a range of cams, creating a design for an automata toy based on a choice of cam to create a desired movement.  

• Understanding how linkages change the direction of a force. 

• Making things move at the same time. 

• Understanding and drawing cross-sectional diagrams to show the inner-workings of my design.

Make

•Measuring, marking and checking the accuracy of the jelutong and dowel pieces required.  

• Measuring, marking and cutting components accurately using a ruler and scissors.  

• Assembling components accurately to make a stable frame.  

• Understanding that for the frame to function effectively the components must be  cut accurately and the joints of the frame secured at right angles. 

 • Selecting appropriate materials based on the materials being joined and the speed  at which the glue needs to dry/set.

Evaluate

•Evaluating the work of others and receiving feedback on own work.  

• Applying points of improvement to their toys.  

• Describing changes they would make/do if they were to do the project again.

Technical Knowledge

• To understand that the mechanism in an automata uses a system of cams, axles  and followers. 

• To understand that different shaped cams produce different outputs.
