Electric motors need a gearbox, A reduction ratio betweem 20 and 100 is the best

It is rather easy to remove a motor from a toy, sometimes with the gears, but before making a robot around reused parts, check the voltage, the power and the noise. Motors with a reasonable current are mentionned "solar motors"

Look at the motor and gears used on CD to extract the disk. They are well designed, motor is usually 12V, but you may get enough power from a 5V supply.

We can recommend two motors

Opitec has a 3-6V motor motor, with a gear box kit to be assembled. Cheap, reasonably low power, but noisy (fill with grease). Two gear factors can be selected at assembly.

Didel does not sell this motor. Order directly from Opitec. They will be pleased to send their catalogue. They have plenty of interesting stuff, including wood, plastic, steel rods.
