Question about a product I need

  • I built a monster handbook of monsters, this guy can not be used, the way I build him he is just a prop.. I would like to make the mouth open and close a couple times like it was chomping toward someone. I have a fish tank im going to use when setting up a booth and I thought it would be a fun surprise for the young muggle children.

    questions

    what is the name of the motor for the mouth im looking for?

    it only needs to go up about half inch 3 or 4 times

    TIA

  • A servo with an arduino would do the trick cheaply. Alternativly you could use the Lego Servo + Battery Box + IR Receiver + Remote. An arduino + servo would cost about $20, while the lego route is more like $80, but much easier to use.
