Cam toys (aka automata) use hand-powered mechanisms to create cyclical motions that animate a scene. Students design and create cam toy machines with moving objects/characters that symbolize abstract concepts and represent dynamic situations.

Gear toys use gear wheels to transfer the power in the toy, to change the speed and direction of motion. They can be powered by hand (with a cram or cam and cam follower) or by wind-up mechanism. The different number of teeth in the gear wheels determine the …

The Basic principle of the Cam is to turn a circular motion in to one that moves up and down. This is referred to as reciprocating movement. In automata this is very useful and is probably the most commonly used mechanical action.

Toys powered by cams and cranks, known also as automata toys. Some of them are very easy to make but others require high level of precision. Learn more about the science behind the cam and crank toys. High-level but good guide explaining how cams, levers and gears work. The information is fine for beginning. Has nice photos. See here.

Here is a simple instructable on how to make a mechanical cam toy out of materials such as paper, cardboard or card. Different uses for this Cam Toy: A classroom display ; A teaching aid to teach how a cams work ; A teaching aid to explain why structural components such as gussets or brackets are important.

2024年9月26日 · gear toys use gear wheels to transfer the power in the toy, to change the speed and direction of motion. They can be powered by hand (with a cram or cam and cam follower) or by wind-up mechanism. The different number of teeth in the gear wheels determine the speed transition from wheel to wheel.

In this project, I aim to explore the design, fabrication, and assembly of mechanisms by creating my own mechanical cam toy. Using Fusion 360, I started with a provided example and customized it to experiment with different types of motion, geometries, and joints.

Use the template CAM MECHANISM - IDEAS - SHEET. The example below, shows how each idea can be set out and the type of notes supporting your design idea. A sample ideas sheet is shown below, with one idea shown completed.

Below are five examples of CAM toys. They rely on an ‘eccentric’ cam, a simple follower and a slide. You are to design and make a similar device/toy. Before you start designing your idea, study the examples below. Select the one and describe how it works and how it can be improved.

This is a cute little visual guide showing how to make a hatching cam toy and how it's not as simple as it look. Nevertheless, the guide is easy to understand and follow. Be prepared for 1 to 4 hours if you want to build a cam toy that works well.
