Very nicely done. Things I like:
- Nice solution for your can gripper
- Running dual elevators on the same towers
- The tilting tower is awesome. That concept didn't make it off our whiteboard. Very nice implementation.

Do you have any trouble stacking on your seed tote? Our prototype testing showed that the slightest misalignment between the seed tote and the incoming tote caused the upper tote to jam on the "bumps" on the lower tote.
