Nice work, looks like you put some thought into the design. Good use of model airplane props.

Are you worried that having the props mounted in a biased configuration (not dead-center on the robot) will tend to make the robot turn or move awkwardly? I assume you offset them to make room for a ball-handling system. Will the airflow pass through the ball system or will you reverse the rotation to reverse the direction of the robot?

On a separate note, have you checked the metal hardware on your collector to make sure it's not going to rip up the balls? Looks iffy to me.
