Here's a card dealing robot that I've been tinkering with. This robot deals from the bottom of the pack using an NXT wheel to draw out a card. A second NXT wheel spinning 5 times quicker then 'spits' out the card. The whole device is mounted on a turntable to allow the robot to deal into different position.
Nothing overly spectacular, but I like how well the different speeds of the two wheels work to kick out the card.
The program is pretty straight forward and I've got image of it on the website, http://www.domabotics.com/projects.php
