Here are some examples:
Simple Machines:
* A car: The engine is a machine that makes the car move.
* A bicycle: The gears and chain are a system of simple machines that allow the rider's pedaling to move the wheels.
* A crane: The motor and cables are a machine that lifts heavy objects.
More Complex Machines:
* A robot: The internal mechanisms and sensors are machines that allow it to navigate and perform tasks.
* A printing press: The motors and rollers are machines that move the paper and ink to create a printed document.
* An airplane: The engines and wings are machines that generate lift and thrust to move the plane through the air.
Things that aren't traditionally considered "machines":
* A ball: While you can throw a ball, it doesn't move by its own internal mechanism.
* A leaf: The wind moves leaves, not a machine.
Ultimately, any object that moves because of some kind of force applied by a machine is moving by a machine.
Could you tell me more about what you're thinking of? Do you have a specific object in mind?
