Device construction?

I'm lacking proper terms and words to explain the device I'm trying to build, but here is my best attempt to explain: 

I want to build a device, that uses simple technologies like a dc motor for example, that moves specified object up and down in a vertical motion, sort of like an elevator except. Or a device which gives the object a jerk which makes it jump up slightly.  What technologies can I use to build this device.

    A simple DC motor, a couple of pulley wheels, some string, a suitable battery, and a switch. Plus the wires to connect everything together.

    You didn’t state what the “except” refers to.

    If you want fine control then a stepper motor salvaged from any discarded printer plus the motor control circuit board will refine the idea.
