While I'm not quite ready to take the plunge like Art has, I did notice something of interest. In
this picture by Mr. Lavery Mr. Shovel-bot is shown surrouded by a line. Upon examination such a line exists no where in the 2005 animation. I don't have the '04 or '03 animations available and they appear to have been lost in the shuffle on NASA's website. However, I don't recall said lines on either field, nor do I see them in picture from the photo gallery. Unless we are being hoodwinked, which isn't exactly a new phenomenon, we are looking at part of the '06 field.
Mr. Shovel-bot is almost entirely enclosed by the blue line, except in the top of the picture you see the line ends. From the supposed size of these robots I can gather that we are seeing around 4 feet of at least an|_ shaped line, more likely a |_| shaped design. This begins the question, why is the robot facing the line? Are we viewing the loading zone of 2006?!!
So the whole point of this post? Folks, there aren't going to be people scoring footballs or whatever the game object is. There will be people giving said object to the robots for the robots to score.
PS: I'm still trying to figure out what that bannana is there for. Is it hiding something?
