That poor robot!

I was recently watching old game animations, and I noticed something funny. In all the games with balls (2004, 2006, 2008) when the voice over says "Robots must be built robustly..." and then it shows a game piece (or several) dropping on the same robot every year, the low blue one that looks like a snowplow. Why is that? I feel kind of bad for that robot now, it's always in the wrong place in the wrong time. Your thoughts?

BTW, who does the voice overs for those animations?
