“Dice” A CRAPS-PLAYING ROBOT FOR YOUR ENTERTAINMENT “ Not your ordinary crappy robot” BY CLIFF PANNELLA

WHAT THE CRAP DOES IT DO?? Place bet Throw dice Retrieve dice Store dice in camera housing area Read values Calculate win or loss; update bankroll Reposition for next bet and roll

SENSING THE DICE Two IR sensors will be placed in front of the robot, one at dice level and one above. If significant differences in readings are found – a die has been located. The robot will then roll over the object to store it in the CMUcam housing area. Once both dice are stored, they can be read.

READING THE DICE RGB color characteristics will be measured by a CMUcam. Individual pixel information will be transferred back to the microcontroller serially using RS232. This information should result in a correct reading, given a high contrast background.

THANK YOU FOR LISTENING HOPE YOU HAVE A CRAPPY DAY!
