Hi,
LEGO Education Center Singapore is organising the Singapore LEGO Global Building
Event on the 7th Sept 2008 at HarbourFront Centre.
This is a family bonding event so grab your kids and form a team. The winning
team will get to represent Singapore at the LEGO Global Building Event at
LEGOland Billund, Denmark on Oct 10 -12, 2008.
Registration is now open and will close on 20th Augyst 2008. So don't wait any
longer all you LEGO fanatics, go to

Subject: Legway with ROBOLAB 2.9
At the recent LEGO Engineering Conference 2007 in Singapore,
http://news.lugnet.com/robotics/edu/?n=177
I showed how kids using ROBOLAB 2.9 could learn about proportional control
and
apply it to their robots like making a model car go a precise distance and a
proportional control line follower.
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=241093
The height of their learning would be to make a two-wheeled balancing robot,
none other than Steve's Legway. Except it would be programmed in ROBOLAB 2.9
rather than BrickOS.
The balancing bot was demo'ed at my talk and drew a lot of interest but
nobody
caught on the significance of it being done in ROBOLAB 2.9 rather than in
BrickOS.
The vi is here for those who want to try their hand at it.

Note how you can write algebraic equations in the expression box.
The OptimizeRCX box is essential for real-time control. It really grinds the
motors, thanks to Dick Swan!
You have to use the EOPD (red) sensor from Hi Technic. I've tried the LEGO
light
sensor in raw mode but it doesn't work as well.
After you press the run button, you have 1 second to set it upright then the
PID
will take over. So far it only does the balancing act. But the kids love it.
I haven't yet figured how to make it spin and follow the line like Steve's
original Legway.
Have fun

Thanks for the heads up, this is wonderful to see. We primarily came up with the
GBC idea for exactly one of the reasons you mention in the PDF - we wanted a
collaborative, not competitive, LEGO event for groups, clubs, and kids. It has
succeeded in ways we never really imagined, and continues to grow.
Was there much interest in this during the presentation? Do you think folks will
try it out? What is the largest GBC you've personally seen (and yeah, they are
*very* addictive)?
As to your rolling ball clock, that's a nice set-up. I think it uses a slightly
different mechanism to catch the "carry" ball from the level above, while still
allowing the rest to dump to the bottom. Sigh, yet another thing I'll have to
put in... >grin<

We've just had our first LEGO Engineering Conference in Singapore with Prof
Chris Rogers as the Keynote speaker.
http://lsl.nie.edu.sg/lego.htm
Among other things I had the opportunity to give three presentations, of which
my favourite is the one on "GBC - A Fun Way to Learn Maths, Science and D&T".
Specifically I detailed a Rolling Ball Display Clock and its relevance to Maths,
Science and D&T.
My other presentations were on "Teaching Children Proportional Control using
ROBOLAB 2.9" and needless to say one on "Evaluating LEGO Air Compressors with
RCX and Control Lab". The models were also on display.
The slides can be found here for educators who might find them useful for their
classes.

Enjoy
