Thanks, it appears that when you view the presentation in the embedded viewer the colors are off, if you download it, it is much easier to read

Questions below are answered in bold:

Perhaps for the superstructure we could have gone thinner, we just went with what we knew worked previously for us
How did you handle picking up three balls?
We kept the hopper open when collecting
Did you have sensors in there to stop the lift until you picked up three balls? (I only saw one stage in the lift/elevator).
The sensor we used (located at the top) was to index the balls for consistent feed.
Did you actually use the hopper as intended with another robot dumping into your hopper?
The hopper was only used for other robots once during competition, however it did allow for human loading as well.
What programming language did you use?
Java
CAN?
At scrimmage and NYC we ran CAN, at CT we ran straight PWM
Did you have any issues with the lift motors at the bottom? (I always understood that you can't push a belt)
We never experienced any problems, our placement of the gearbox was to keep the weight as low as possible.
Thanks for the positive comments, if you have any other questions feel free to ask.
