Mechenical toys

This mechenical toy is moved by its gears. It is a simple example to show how gears work. To enable it to move, the wheels are rotated and thus creates a force to enable it to be moved. For this toy, it is built in such a way that it can move in different ways as its wheel has a paticular shape so as to synchronize with the other wheels.
