this may have been posted, but I agree it seems to look like some sort of ball track system, and it is shown upside down in the picture. but on that note, the yellow lexan doesn't seem like an ideal design for holding up the track, but more so a bracket for something hanging below it. My thought is maybe some sort of sensor mounts on that bracket to count the balls as they roll by.

Maybe these balls are scored on a goal above the driver station and this is part of a track to corral them back to the human player, sort of like what was done in 2006
