Would love to get together with you and talk about the set, share ideas, etc.

Or do you know ne1 that has the set? Or plans to get it? Or is leaning toward getting it?

Y’all may remember me from two Austin meetings: the last one I went to was 2002 (I think), which met at NI and I sold a lot of my LEGO (made like $400). I sold some cabinets of LEGO and most of my train stuff.

But I did not sell my LEGO Tecnic parts or LEGO robotics stuff, knowing that someday I would use them again... Perhaps that day is now.

PS--Little did we know that NI would be the software develop for nxt. Or did we know that? :)

All,

Come on by the next Austin TexLUG meeting this coming
Sunday.  (And yes, it *is* on Mother's Day.  Show your
Mom you love her by getting out of the house for a
couple hours!)  Particulars are below.

If you have a creation to show, bring it.  I'll be
bringing tiles for the upcoming line-following
contest (the paint is drying as I type this), so if
you'd like to try out your 'bot before the 6/11
contest, now's the time.

For contest details, see:

Folks,

The Austin chapter of the Texas Lego Users Group
(TexLUG) is holding a robotic line following contest
on June 11, 2006.

In this line following contest, robots attempt to
complete a specified race course by following
a black line on a white background.  The robot
completing three laps of the course in the shortest
time is the winner.

There will be two age groups for the competition,
under 13 years old, and 13 years and up.

Complete rules may be found here:

  http://www.io.com/~rueger/lego/texlugaustin/line2006/

as well as helpful links to other line following
robots.

Folks,

Attending the 3/12 TexLUG Austin meeting were:

  Louis Davis
  Lee Rahe
  Tim Rueger
  Ed Southerland

Ed brought a few more of his custom minifigs, but most
of his MOCs were really nice xpod-based spaceships.  I
really liked his stylings in various space themes,
including Blacktron, M:Tron, Ice Planet 2002, Spyrius,
and Life on Mars.

Lee proudly showed off some excellent-condition pieces
from his recent vintage Lego acquisitions.  I, for one,
was very impressed with the details that Lego's
injection molding was achieving in the late 50's and
early 60's.

Louis was a first-time attendee; he got a Mindstorms kit
around Christmas, and was looking for help and ideas on
what to do with it.

On that note, I showed a simple line following robot
from Jonathan Knudsen's O'Reilly Mindstorms book to
demonstrate an upcoming line-following robotics contest.
Look for rules and schedules to be posted in the next
week.

Adminstrivia: I'd mentioned to a few folks that the
Little Walnut Creek library was scheduled to be closed
for remodeling in May 2006.  However, the remodeling has
been delayed some months, so I'm working on extending
our 2nd-Sunday meeting slot reservation there for as
long as possible.

Please keep in mind that we will eventually have to find
a new place to meet.  If you have any good suggestions,
please pass them along (either to the list or by private
email).

Play well,
-Tim

All,

The next Austin TexLUG meeting will be this Sunday,
March 12.  It's been a few months since we've
gotten together, so come on out and show off what
you've been working on!

I'll be shortly announcing and posting rules for
a line following and maze solving robotics
contest, just to keep y'all sharp while we await
Mindstorms NXT.  Look for a demo at the meeting.

I'll also be bringing the mountains that I
provided for the recent display in San Antonio,
along with my photos from the event.

See you there!

Folks,

My wife and I will be traveling 12/29 to 1/9,
so I won't be attending the TexLUG Austin
meeting on Sunday, 1/8.  (I tried to find an
alternate venue and/or time, to no avail.)

The procedure for the meeting room at the
LWC library is very easy; whoever gets there
first, just ask someone at the front desk for
the key to the meeting room.  Also, make
sure the room is back in its prior state when
you lock up to leave.

The next following scheduled time is Sunday,
February 12.

All,

The next Austin TexLUG meeting will be this Sunday,
December 11.  It's been a little quiet lately
in TexLUG land, so come on out and show off what
you've been working on!

I'll be bringing photos of this Saturday's First
Lego League meet in Austin.  Come by to see
what the teams came up with to solve this year's
Ocean Odyssey challenge:

I'll also have an 8455 Backhoe Loader to demo.
It's an out-of-print set that I finally got
recently.  It's a pneumatic marvel.

See you there!

All,

Here's a recap of last Sunday's TexLUG meeting in
Austin.  Our building theme was castle; we also put up a
Great Ball Contraption and held a robotic sumo contest.

The meeting was well-attended, despite the last-minute
change of venue from National Instruments to the Little
Walnut Creek library.  Among the regulars were Ed, Kurt,
Laura, Lee, Mark, Pat, and myself.  Also attending were
three sets of kids/parents who entered the sumo contest:
Evan Ryker and his mom, Michael Johnston and his dad,
and Joey and Gavin with one of their dads.

Ed and Lee brought in a nifty set of castle MOCs.  Ed had
a number of small scenes with some of his as-always cool
customized minifigs.  Lee's black castle was also
stunning.  (I wish I'd taken more time to admire and
photograph them, but I was swamped with GBC and sumo.)

Kurt brought in his fleet of Texas navy ships.  It was
really cool to see them all on display at once; he has
done a fantastic job maintaining style and detail across
his various sailing ships.  His cutter is still in
progress; I and others had a couple suggestions for
working out a few details on his railings.

Laura and I showed off a small Great Ball Contraption,
which got a lot of crowd attention.  Laura brought in
her scoop lifter module and James Loftus' ball counter.
I had a rather free-form multipart construction, which
Laura eventually managed to work into a loop with the
other two modules.  She was justifiably miffed at my
lack of adherence to GBC module standards; next time
I'll make my things fit.

James' ball counter dutifully registered a total of 1465
balls while we ran the loop.  The mpg of the GBC is a
little shaky (I used the movie mode on a small digital
camera), but it captures the ball movement nicely.

The sumo contest was well-attended, and got lots of
great reactions from the crowd.  There were four
entries, so there were six round-robin matches in all
(two points were awarded for a win, one for a draw):

                            Y    J    M   SoF    Total

Yokozuma (Evan)             -    1    0    0       1

JoJo4000 (Joey & Gavin)     1    -    0    1       2

Michael10000000 (Michael)   2    2    -    0       4

Son of Flatliner (Tim)      2    1    2    -       5

Evan's Yokozuma was a low-speed caterpillar tracked bot,
while both JoJo4000 and Michael10000000 also used
caterpillar tracks and ran somewhat faster.  My bot was
an unabashed rework of Steve Hassenplug's Flatliner
sumobot which he showed at Brickfest:

  http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1352550

My enhancement was using rows of teeth (vs. Steve's
flags) as the edge of the wedge surface.  I also had to
fit it inside the 30x30 stud dimensions required by the
rules.  (I'll post more details shortly.)

The two tie matches were the most fun: Yokozuma held on
for the full 3-minute duration of the match against
JoJo4000, and was pushed off the arena only a few
seconds after time elapsed.  Son of Flatliner's match
against JoJo4000 ended quickly when both bots spun off
the edge of the arena simultaneously.

I also gave a brief talk about my Brickfest sumo contest
experience, and demonstrated my super-slow, uber-complex
Remington sumobot.

All in all, a fine meeting, especially considering the
last-minute difficulties in bringing it off.  Many
thanks to everyone who helped make it a success.

All,

The next Austin TexLUG meeting will be this Sunday, the
11th of September.

I'll be showing some of my photos from Brickfest 2005.
I took over 600 shots, covering just about everything,
so whatever your interest, come by to see the great
creations people showed off.

I'll be demoing my entry to the Brickfest Super-Mega
Sumo contest, which was easily the most complex of the
entries.  (And not surprisingly, also didn't perform
very well.  But wait til next year...)

And speaking of sumo, if you have a first-cut 'bot for
the October meeting sumo contest, bring it and give it a
spin.  As a reminder, rules and helpful ideas can be
found here:

Folks,

There will not be an Austin TexLUG meeting this coming
Sunday.  I'll be at BrickFest in DC this weekend, and
I'm still arranging new reservations for the room at the
library.

Plan on our next meeting for Sunday, September 11, 2005.
(I will inform y'all about any changes.)

In September, we can start planning in earnest for the
October all-TexLUG meeting at National Instruments.

I'll also be bringing my photos from BrickFest, as well
as my entry for this weekend's Super Mega Sumo robot
contest.  (It's 3.5lbs of screaming Technic goodness!)

See you next month!

-Tim

Folks,

Attending the 7/10 TexLUG Austin meeting were:

  Danny Diaz
  Clendon Gibson
  Laura Hayden
  James Loftus
  David Perdue
  Ed Southerland
  Tim Rueger
  and others

Ed brought his latest custom minifigs in a scene from
Legend of Zelda.  He also showed his nicely-done HG
Wells time machine model, using the clock face from the
Harry Potter Hogwarts Castle.

David demonstrated a three-wheeled line-following robot
with a front-mounted light sensor on the directional
wheel (see photo below).  It was built in an elegant
modular fashion, with the light sensor assembly and each
drive wheel built for easy removal.

We assembled a Great Ball Contraption (TM) with modules
by James, Danny, Laura, and Tim.  It was great fun
seeing the whole thing in action.  The first three, who
work for National Instruments, had previously built
their modules into a GBC at an NI event, while Tim
hastily built his over Saturday night and Sunday morning
to join in the fun, and to try out a module before
Brickfest.  (Videos of the NI GBC are available; we're
looking for a place to host them.)

In addition to the GBC module, Tim brought his sumo
contest robot for demonstrations, as well as a drive
train mockup for the 2005 Brickfest 3.5-lb mega-sumo
robot contest.  There was some discussion about how to
prevent stalls in RC motors, since the power must be cut
so they can recover (a nasty characteristic for sumo
contests).

Tim also brought the brand-new 8421 Mobile Crane;
everyone there was impressed with its scale and
function.

Laura showed off her Deal of the Month (TM) - a Technic
8454 Rescue Truck which she scored as an open (but
complete) set from Kaybee for around $20.

Clendon asked lots of good questions about the RCX,
while two other members of the general public stopped in
to check things out.

All in all, an excellent meeting.  I'll be at Brickfest
in Washington, DC next month, so arrangements will be
made to get the room opened up for the next meeting.

-Tim

Folks,

Come on by the next Austin TexLUG meeting Sunday,
July 10.

Bring your latest creations, or share some tips on where
you've gotten good deals lately - Target is putting Lego
on clearance up in Dallas, hopefully the same is true
here in Austin.

I'll be bringing the brand-new 8421 Technic Mobile
Crane.  This model is a real beast!  For a preview, see:

See you there!

-Tim

PS - I'll be at Brickfest in DC during August's meeting,
so we'll need someone to open up the meeting room next
month.

Folks,

Attending the 6/12 Texlug Austin meeting were:

  Kurt Baty
  David Perdue
  Lee Rahe
  Tim Rueger
  and many assorted others (see below)

We held the first TexLUG Austin Lego Mindstorms Sumo Robotics
contest.  About twenty people were in attendance, from TexLUG
regulars, to robot team members and parents, to robotics
enthusiasts and other generally interested folks.  Everyone had
a great time.

There were five robot entries: two from David, one from Tim, and
one each from AustinMetroGifts ("Team AMG", a group of
8-to-10-year-old homeschoolers from Austin and the surrounding
area) and Evan Ryker, age 14, another Austin homeschooler.

David's first entry used a novel light sensor configuration to
detect opponent collisions and the black sumo arena border with
the same sensor.  His second was a lightning-fast, but erratic,
variation of a Zip-Zam bot from his "Competitive Mindstorms"
book.

Tim's entry implemented a two-speed transmission (a fast speed
for searching and a slow speed for torque/pushing), with two
front bumpers for turning toward a detected opponent.

AMG's robot was a two-tread design with a light sensor in front.
They had trouble getting their robot working consistently, but
we worked the matches out anyway.

Evan's robot was also a two-tread design, with a very slow,
very high-torque drive train.  An arm assembly in front was
designed to raise an oncoming opponent off the arena.

(Photos of all the entries may be found via the links below.)

The contest was structured in two rounds.  First, a round robin
tournament matched each robot against every other one.  The
total wins in this round determined the placement in a final
single-elimination bracket to determine the winner.  (For the
rule set, see the URLs below.)

After the round robin matches, the scores were:

Tim - 4 wins
Evan - 2 wins
AMG - 2 wins
Perdue #1 - 1 win
Perdue #2 - 1 win

The elimination bracket was thus:

Play-in: Perdue #1 vs Perdue #2
Semifinal 1: AMG vs. Evan
Semifinal 2: Perdue1/2 vs. Tim
Final: Semi 1 winner vs Semi 2 winner

David's #1 robot beat his #2 in the play-in round; #2 had
difficulty staying on the arena due to its high speed.

In the first semifinal, Evan handily pushed AMG off the arena,
ending a very enthusiastic run by the AMG team.

In the second semifinal, Tim hung on to beat David's #1 robot.
A spectacular entanglement occurred during this match: one of
David's large motorcycle wheels got ensnared in the yellow
elastic band which held Tim's front bumpers open.  David's
wheels kept turning, so the elastic caught and wound around the
wheel *multiple* times, while, astonishingly, *not* breaking - a
true testament to the resilience and quality of Lego components.
An entanglement was eventually declared, and David's robot had
to be disassembled to release the elastic band to finish the
bout.  (And I didn't bring any spare elastics - yikes!)

In the final match, Evan's superior tread friction won out over
Tim's complicated high-torque transmission.  Tim twice became
immobilized when trying to push Evan's bot off the arena: Tim's
transmission changeover catches were driven by clutch gears,
which didn't hold the catches in place when the transmission was
subjected very high opposing force.

Evan took home the grand prize, a Technic 8435 4WD set.  The
runner-up prize of a Technic 8415 Dump Truck will be given away
at a future TexLUG event (Tim donated the prizes).

Many, many thanks to all who came out and helped make this a
very fun, exciting day.  I'm looking forward to seeing more
folks at TexLUG meetings in the future, and to other robotic
competitions.

-Tim
