Well, there was one robot that didn't have this problem too much. The one
picture of a cube mysteriously perched on edge next to a board is not doctored -
*somehow* my robot just clipped the cube as it left the board, rolling it out of
the cell and just by some wild chance catching it like that. But that was about
the only time mine had a problem.

I saw it slightly differently - too often,the cubes seemed to bounce slightly
in the cells upon being dropped, and sometimes this would result in the cube
ending up cocked up on one wall of the cell.

It would not help me at this point, as it's really not a problem I have. My
mechanism places the cubes to within 0.5 studs horizontally, and "drops" them
less than 2 plates vertically - they *can't* bounce out, because the EOAT traps
them in place.

Just have the robot drop you cubes on their sides - the only rule that way is
that cubes should never be placed in a cell "bottoms up". Put them in on the
side and they'll slide just fine across the studded floor of the cell.

I'd vote no at this point - it's a problem that can certainly be solved.
