[Lil' Lavery]

We used an old suction device at the end of a small shopvac and found that it can form a nice seal on the flat portions of the totes on either short end (where the FIRST logo it). You would still have to find a way to raise the totes and control for rotation of the tote as you raise them (similar to how many hook designs have to control for rotation), but it's potentially do-able. We will not be pursuing this design further, though. We liked our other prototypes more, for numerous reasons.
