<p>The present invention relates to a present delivery device for an RC submarine currently used for that purpose. In order to deliver a present with an RC submarine, a rack pinion gear holds out the present through an inner antenna, using the wireless transmitter and receiver of the RC submarine. A magnet set to the present is attached to an electromagnet formed in the end of the antenna of the RC submarine. The polarity of the electromagnet can be changed by the wireless transmitter and receiver. As a result, the present and the present transfer RC submarine can be separated from each other.</p> |
