2015 2nd Choice Robot

[IronicDeadBird]

One thing I love about FIRST this time of year is I get to look back at what I originally though was a viable idea and then realize how dumb I was.
What did you guys think was viable this year but you didn't use for various reasons?
I think my favorite idea this year was two minibots tethered to a robot on one end of the scoring platform. Totes would be brought to the robot that creates stacks and the stacks would then be pushed onto the scoring platform.
What were your guys initial thoughts that you didn't go with for various reasons?
