Now don't be bitter, Greg.
Team A> brought three entries...
1) the big tower bot
http://www.brickshelf.com/gallery/ffaat/RTL19img_0680.jpg which was
built by my son and I the day the rules were announced, using every
1x16 tecnic brick in our house, as well as the somewhat unorthodox
method of reinforcing with old blue rails (I KNEW there had to be a
use for them!). It sat without a "top", as I couldn't figure out a
nice "lift" or "elevator" mechanism. until the latching rod came to me
in a dream, and the day of the contest someone (thanks whoever)
suggested it be spring loaded.
2) an actual "robot"
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1383785 (i.e. had a
rcx controlling it) that I built built after deciding that a tower was
a "loophole-bot".
3) the "gravity ring" http://www.brickshelf.com/gallery/ffaat/RTL19/img_0631.jpg
I was only going to bring #2, but my son wanted to see the big tower
go head to head against other people, so I said he could run it.
My daughter pouted at me and said "but what can I use" so we quickly
built the gravity ring. She thought it was stupid, until I showed her
my "real" robot couldn't beat it (even Dave K's runamok couldn't take
it apart)...And I was impressed that others independently came up with
a similar solution
I knew in advance that the only one of the three I would call a
"robot" was going to loose to the other two, as they did at home, but
that didn't stop us from playing all of them, even when my RCX hit the
ground repeatedly and still managed to finish in a resounding last
place (0 points, no wins, lost ever match).
After all - I thought he point was to have fun and see how others
approach the same problem.
The other two were valid strategies within the rule set
Now, the tower did loose against Dave K:
http://www.brickshelf.com/gallery/ffaat/RTL19/img_0665.jpg in a rather
spectacular fashion after being hoisted 9 feet into the air, and was
rebuilt by that 10 year old, with his mother's help (who, by the way
can not stand to build with Lego).
And even under the proposed rules, a motorized lift mechanism plus a
tower an inch shorter would still be able to compete, so to have true
sumo on a stick, rule 1) should be amended to:
"No part of your robot may touch the floor at any time during the
contest, except for pieces falling off, NOT BY DESIGN."

| (...) Or how about: 1. No part of your robot may touch the floor at the BEGINING of the contest. 2. At least one powered motor must be used. Both these rules would prevent my dad from building me a big solid tower that just hold my end up. -Greg (19 years ago, 11-Sep-05, to lugnet.org.ca.rtltoronto)
