Racquetball Challenge?

Now that the rack is done we have a new, and more difficult challenge ahead of us. We are required to design a ball lifting system on our robot, and make it drop it into a tube. This week we are planning on creating the ball lifting mechanism and placing it on our robot.

Here is the tube and the ball that we have to get into the tube.

Here is the design to grab the ball and drop it into the tube.
