How to design automata and mechanical toys

How to design automata and mechanical toys
Brief History of Automata The following buttons will lead you on to a number of topics designed to help you understand more about mechanisms, basic engineering principles as well as designing and making your own automata and mechanical toys. Craft Education have two books entitled: 'How to Design and Make Automata' and 'How to Design and Make Simple Automata' as well as aCD-ROM for more information click on the links below. Tools and Construction Techniques How to contact us If you want to know more about designing and making wooden automata and mechanical toys then the CD-ROM How to Design & Make Automata, Mechanisms & Mechanical Toys will prove invaluable. PDF Download or Book How to Design & Make Simple Automata PDF Book How to Design & Make Automata You can now download the CD-ROM as a complete file for only £17.50 and is available Worldwide.

Magnet Man - Cool Experiments with Magnets Cool Experiments with Magnets This web site is devoted to magnetism and the cool experiments you can do with permanent magnets and electro-magnets. Some of the experiments are very basic - things you've done since third grade. Others are unique - perhaps you hadn't thought of doing some of these before, or had difficulty in trying to set them up. Lists of the materials needed for the demonstrations, directions on how to assemble them, instructions on how to show them, and notes on how they work are all here for you. Also shown are several cool magnetic toys you can buy. Have fun with hands-on experiments! Rick Hoadley(For other cool toys and puzzles, check this out!) Last updated: 26 Feb 2017. , that means that at the underlined link there is some kind of experiment you can buy or build which will help you learn about the world of magnetism. Safety Considerations IMPORTANT! What is attracted to magnets? Electromagnets What is an electromagnet? Who else has cool stuff on magnets?

Teaching and Learning Resources from Diane Hawkins Unit 3C - Moving Monsters (ICT Unit 3A - Combining text and graphics) About the Unit This unit helps to develop children's understanding of control through investigating simple pneumatic systems and designing and making a model of a monster that has moving parts controlled by pneumatics. This could be linked to stories or poems, or another purpose. A good context is toys to amuse children who are ill in bed. The designing and making assignment requires children to develop skills in working as part of a team.

Simple animation to explain complex principles - Electronics 1, aircraft radial engine 2, oval Regulation 3, sewing machines 4, Malta Cross movement - second hand movement used to control the clock 5, auto change file mechanism 6, auto constant velocity universal joint 6.gif 7, gun ammunition loading system 8 rotary engine - an internal combustion engine, the heat rather than the piston movement into rotary movement # Via World Of Technology. 1, inline engine - it's cylinders lined up side by side 2, V-type engine - cylinder arranged at an angle of two plane 3, boxer engine - cylinder engine arranged in two planes relative Simple Mechanics Cams The basic principle of the cam is to turn a circular motion into a linear one. This is referred to as reciprocating movement. In it's simplest form you turn a handle to make something move up and down. The cam-follower is connected to, and part off, a shaft known as the Push-Rod. The push-rod controls the direction of motion and transfers the cam's movement. They are found in many machines and toys. Concentric Cams An concentric cam is a disc with its centre of rotation positioned 'off centre'. As it rotates it pushes the flat follower upwards and then allows it to drop downwards. A mechanical toy based on a series of concentric cams is seen below. More Examples Below is a mechanical toy based on a CAM mechanism. Designing Cams In order to design a cam you need to know what you want it to do. The cam-follower has lifted by this amount. Calculating Lift The concentric cam, is a circle with an offset center. Cam-follower Plate Cam Shapes Remember that the cam-follower has to work smoothly.
