Actually yes. I believe they had one piece that was not disconnected at all, so they placed it on the robot, connected them to the robot frame and went. They had them laying around in the pits at Florida and Atlanta, where I took a close look at them both times, thinking that they were illegal both times.
The actual plywood pieces were not connected, but the bumpers were all connected in some way.
Check out the picture from TBA and the gold piece you see inline with the bumpers is a part if the bumpers itself.
Do not take my word for this, as I am not positive, but I am pretty sure about this.
