BrickFair VA 2013 MINDSTORMS Contests

BrickFair VA will be holding four separate contests for LEGO MINDSTORMS
enthusiasts this year.  The long-running favorites Stock Sumo and Unlimited Sumo
will be held again as usual, and there are two new contests as well, Capture the
Flag and Journey to the Center of the Earth.

In Capture the Flag, two robots will face off from opposite sides of the table,
and the winner will be the first robot that can locate the flag, grab it, and
find its way back to home base.  The flag is represented by an infrared
HiTechnic ball, and as an added complication, it starts out on a flag carrier
robot that is wandering randomly around the arena.  This contest is recommended
for AFOLs, although FOLs of all ages are welcome to compete.

Journey to the Center of the Earth is a variant of last year's Mine Rescue that
will find out which of the robots is best equipped to help minifigs explore the
deep underground.  Contestants must follow a line drawn on the table, access a
plastic bore hole, and lower a minifig safely to the bottom.  This contest is
recommended for KFOLs and TFOLs, although FOLs of all ages are welcome to
compete.

The official contest rules can be found at the following links:

Journey to the Center of the Earth:

Stock & Unlimited Sumo: http://www.brickfair.com/game/pop/SumoRules.pdf

BrickFair VA will be coming to the Dulles Expo Center in Chantilly, VA from
August 1-4, 2013.  Public hours are on August 3rd and 4th from 11:00 AM to 4:00
PM.

Autobotics


This is a robotics workshop and deals with the design, calibration of a
line-tracer robot. It also meets the following specification match:  wall
tracing, line tracing and edge detection. (It’s basically a lower end
robotics workshop when compared to Self-Balancing Robot.). The workshop is
done by a partnering group called MBS Group.
The link of Autobotics is as follows:

Click on the "Official LEGO Belville website" in LUGNET header, and it redirects
you to the LEGO Friends site. So I guess Belville is coming back in the form of
the LEGO Friends.

SMART's BrickCon Display

I want to thank everyone who participated in this year's SMART display at
BrickCon. It was absolutely amazing! We couldn't have done it without everyone's
help. Every element was crucial, and worked amazingly! Named "BallMageddon"
because either it was going to be a catastrophic failure, or a spectacular
exhibit that everyone who saw it would remember for a LONG time! I'm very
pleased to say it was the latter!

Here's who contributed:

Gus designed the display and an amazing 'wave' that carried the balls in front
of the display.

Kyle built the final lift that brought the balls into the display, as well as
the sorter that took the balls coming out of the display, and returned them to
their proper bins.

Andrew built the "rainbow stairs", one of the two most commented on parts of the
display, which took the balls coming out of the display and gave them their
initial lift to get them rolling towards their destination.

Sean built a wonderful ball escalator that took the balls from near ground-level
and got them all the way to the top of the bins where they got sorted by Kyle's
sorter.

Of course the wonderful and beautiful hoppers built by Dan were essential. I'm
not sure how many versions he built before creating one that wouldn't jam. Now
he understands the many ways that balls will form voids when you try to pull one
out of a pile. I'm not sure that he entirely believed us when he volunteered to
build the hoppers. Also worth mentioning here is Doug's interesting pattern to
stretch bricks to allow such large bins to be built with a limited supply of

Cavern exploration robot

Hi all,

those who would like to follow our new project, please go to

www.convict.lu/Jeunes/RoboticsIntro.htm and follow the "Casemates project blog".

The idea is to design and program a robot that can navigate through the
casemates, which are sorts of caverns beneath the city of Luxembourg, left
behind by old military occupants (French -Vauban 17th century-, for instance).
As our boarding institution is built upon an old vestige of a fortress, we still
have an access to some casemates that have never been explored. In this project,
we will combine metallic Tetrix and LEGO Mindstorms parts, as a very robust
construction is needed to overcome the difficult topography. (Note that Tetrix
robots may be Mindstorms-controlled and is compatible with the geometry of the
LEGO parts.) 

http://www.tetrixrobotics.com/
http://news.legoeducation.us/Newsroom/Item.aspx?art=2752

(Also note that the blog is entitled "Boulette Institute of Technology", a funny
student usurpation of the great East-coast institute's name. To explain
"Boulette", this is much more complicated... you need to understand French, and
know parts of the boarding institution's history.)

NXT motor parameters


Hi all,

I came across Philippe Hurbain's excellent website sometime ago. On the
Motor Internals page, there is a link that points to Ryo Watanabe's page
containing information on NXT motor parameters. On that page, the torque
constant (Kt) and back-EMF constant (Kb) have rather different values. In
theory, they are supposed to be numerically identical when using SI units.
Naturally, some level of empirical error is expected when data is derived
experimentally. However, the discrepancy between the two values is large
enough for one to question the validity of the data used for deriving the
motor constants.

http://web.mac.com/ryo_watanabe/iWeb/Ryo%27s%20Holiday/NXT%20Motor.html
http://web.mac.com/ryo_watanabe/iWeb/Ryo%27s%20Holiday/NXT%20Motor.html 

I've emailed Prof Watanabe a couple of times already without getting a
reply. Could anyone shed some light on this, please? Thanks.

Cheers
Hippie
