   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.

What I have found is that if you miss by even a little bit, the
cube will get cocked in the hole and it catches on the studs at
the bottom of the hole.

   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.

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.

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.

Can I get a vote on this?

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

In the posts regarding the get together for 3T, it was mentioned that all the robots had a few issues getting cubes to sit flat in the holes. I have spent a lot of effort to tweak my drop locating method so that it hits the holes perfectly. What I (...) (19 years ago, 7-Jan-06, to lugnet.org.us.laflrc)
