Their big ball grabber worked well in 2001, so thats coming back. Their small ball mechanism was partially decent in 2000, so it probably didn't make the final cut. However, they may have wings for corralling. 2003 technology has probably inspired the hanging mechanism. And they'll probably do it from off the platform. I don't know what they would use from their 2002 robot. That was quick and dirty. Now I'll go look at the thumbnail image of their robot..
[edit: with that much room in their robot, I hope they have a small ball mechanism
