Cubes aren't cylindrical or spherical.

Consider this: if you look at pickup mechanisms for FRC for 2006 (or 2004, or 2002, or any other FRC or FTC or VRC game involving balls), they were developed for spherical objects, which a flat plate works for. However, VRC's Elevation uses cubes, which aren't spherical, though they could become that way after going through a flat-plate pickup system!

Other ideas could easily be derived from some of the above teams.
