Hi all,
I am trying to get some middle school kids playing a bit with the robosoccer
idea. I don't want to frustrate them with the fluctuating IR ball. So, I am
planning to find a constant "lighted" ball for them instead, but no luck.
Wonder if anyone may have a suggestion.
By the way, the official IR soccer ball has a very unreliable IR emission.
there are times my IR sensor just simply did not get any feedback even when
it is right next to it. For my high school kids, I had them to implement
some kind of either probability, or just simply skip the reading if there
are spikes of drop. Therefore, for the younger ones, I'd like to find a
lighted ball. any suggestion is appreciated.

I'm not sure if this is a right forum to ask for this. I am wondering if
there is anyone who may be interested in working with 10 high school kids on
learning how to do robosoccer.

How might I implement a pop-up parts description when a student points the mouse
at a part on the screen? Granted this procedure needs a library of part names
in the language of choice.
I imagine having to define a collision mask around the part and declaring it as
an object. On mouse-enter, the pop-up appears with the correlated description.
Does anyone know how to link another program to the NXT constructopedia?
Best,
Edwin Pilobello

I want to try using game software to help children, junior high and high
school kids, explore fundamental A.I. Any suggestion out there? I have
started in looking into Multimedia Fusion Development Software. I'd like to
find out if there is better resource out there?

John Hansen has released a utility that's great for projecting the NXT screen
for the entire class to see. There are two versions in a zip file.
<http://bricxcc.sourceforge.net/nextscreen.zip>
I've already used NeXTScreen2 in class to demonstrate how to use the View mode.
It worked marvelously.
To run:
1. Download and unzip the two versions of the utility to a folder of your
choice. NeXTScreen2 displays a graphic of the NXT with clickable buttons.
NeXTScreen just shows the screen with text icons for buttons. Both work the
same way.
2. Run the version of your choice.
3. Connect the NXT to the PC using a USB cable and turn it on. Start polling by
pressing Ctrl-P on the PC.
4. Proceed with your demonstration using your mouse to click on the button
icons on the PC. Your actions will also actuate the NXT as if you had pressed
its keys directly.
There's more to be found in the original discussion in lugnet\news\Robotics\nxt
under the heading "Another new NXT Utility"

I initially thought it might just be because of the lego light sensor being
incapable of recognizing the light difference for a slight tilt. Then, I
thought, if that's the case, perhaps I can mount 2 light sensors on the same
port to increase the sensitivity. Then, use 2 light sensors simulating the
self-alignment...

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.
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=242330
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<
