What I have found is that if you miss by even a little bit, the

   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.

Either way, tiles at the bottom of the cell would allow the robot to "push" the
cube back in the hole so it isn't cocked.

This leads me to a suggested board modification that would probably
help all participants equally by improving our reliability.

   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.

My robot also supposedly has .5 stud accuracy..but  :)

I suggest that we modify the board to have tiles at the bottom
of the cube holes.  This will allow "sliding" the cube a little
after it is dropped.

   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.

Dropping cubes on their sides does not overcome this problem.  The edge of the
cube still gets caught on the studs at the bottom of the cell.


Can I get a vote on this?

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

Well then your vote doesn't count  :)

(...) True, but... I guess my main concern is that as it stands, everybodies can work (I think) with an occassional nudge or human touch to "correct" a cube.

(...) 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 (...)
