Dear Claude,
I tried to send a direct e-mail to you but it was returned. I am working on my
next art making robot and Erik’s Plotter vi’s are just what I need to adapt to
my software. I will be using a balancing mobile as the plotter.
May you send me the vi library for Erik’s Plotter to my e-mail? tom@tomlohre.com
It would be just the thing to keep me focused on my problems.

I completely missed your question. Sorry about that. But I see that you found
help. Great!

I am working on recreating Vision Center vi in RoboLab 4.9.
Currently my Vision Center vi: Threshold, MorphOpen, MorphClose,
MorphProperOpen, MorphProperClose, MorphThin and Invert causes a clear outline
in the build window.
When I try to recreate it in RoboLab, I have trouble figuring out if, it is
truly binary. When I get to the point of inserting the Morph.vi's the resulting
image blacks out. Sometimes it is there but faintly. Below are both vi’s
although I do not know the extension of the Vision Center Command. Ultimately, I
will address the outline in the image and have the Lego motors draw it in
pencil. The outline created in Vision Center Build Window needs to be my working
image. At this point, it can only be exported out of Vision Center Build by
right clicking on the image. Therefore, I must recreate Vision Center in
RoboLab.
My work: http://tomlohre.com/lego.htm
vi's used:
Vision Sensor: http://tomlohre.com/labview/11.0912
RoboLab vi: http://tomlohre.com/labview/091202W.vi

I don't know for certain but I would be a bit surprised if Robolab works with
the Spybot bricks. There would have to have been a new release with
modifications specifically made to support the Spybot. Searching these
newsgroups suggests that support for the Spybot was never added to Robolab.
http://news.lugnet.com/robotics/?n=23159
NQC, on the other hand, includes full support for programming the Spybot and API
functions designed specifically to take advantage of all the capabilities
specific to the Spybot brick.

I'm not sure if MacNQC was updated with all the Spybot support but I think it
was. The BricxCC help files or the latest NQC Guide PDF file are probably your
best bet for learning what API functions can be used with the Spybot and how to
control its motors and sensors. BricxCC includes several small programs for the
Spybot written in NQC. BricxCC also supports programming the Spybot in LASM and
MindScript if you want to try something other than NQC.

The Spybot firmware is onboard the brick permanently and it cannot be replaced.
There is no need (or ability) to download a firmware to the Spybot bricks.

No language war intended, but for now I'd rather use Robolab.
That said, if I change my mind I'd appreciate some tips on using MacNQC with
Spybotics. Most of the stuff that I've seen on the web talks about using the
regular RCX stuff. One of my biggest questions is whether I need to download
firmware from the SDK to the Spybotics controller. All the stuff I see talks
about getting the firmware from the Mindstroms SDK for the Mac but the Lego
Mindstorms web pages for that SDK are long gone. I've downloded stuff from the
program that comes with Spybotics. Is that sufficient?
Thanks in advance.

I don't know if RoboLab will work with Spybotics, but if you have prior
programming experience NQC may be a better option. It works great with
Spybotics.

Does anyone have any experience using Robolab with a Spybotics kit? I just got
a couple of old Spybotics kits for my son this past Christmas and would love to
program them with him using Robolab. I have lots of programming experience,
although I am new to Robolab, Spybotics and robotics in general. Any tips or
links to useful information would be appreciated.
Thanks in advance.

Sorry, I don't mean the duration, not hysteresis.

Subject: multiplex 2 touch sensors on a single RCX port
I have these 2 touch sensors multiplexing on the same input port. Their raw
values are 47 and 39. I tried to set up 2 separate events, one for the
range of 45 to 50 and another one for 35 to 40. However, the one for the
lower feedback often set off the higher value range event instead. I set the
hysteresis to .5 or even one second, it does not seem to help. Suggestion?

I solved the problem by migrating to LabView. I look forward to learning how to
send programs to the RCX via LabView.

I am working on a program that uses RoboLab 2.9 with the camera. When I open the
Vision Center I get an image but when I run my program I get no image just black
then a speckled image. I tried running my program with Vision Center running and
got the same error. I did get an error code from RoboLab that the camera had an
error in transfer. I downloaded new Logitech Express drivers which did not help;
I then moved the program to another computer with the original Lego camera and
got same error. You can download the program at http://tomlohre.com/080427.vi.
Never heard back from Tuffs about where
http://130.64.87.22/robolabatceeo/college/tutorials/image_cli/index.htm went to
but you can more or less get the beginning information from the Unofficial Guide
to RoboLab, http://www.collegehousebooks.com/lego_bricks_3.htm . Someday they
will write a revised book that covers all the advanced commands in RoboLab.
Thanks for all your great help. I could not advance the science without the
excellent help from the Internet. My Lego MindStorm Painting Machine had its
debut. Here is the link for the story: http://tomlohre.com/VHG08.pdf . Now I am
trying to give it vision.

I am attempting to turn the reflective light on and off periodically. It
works fine in RobotC. However, in Robolab, once it is turned off (via the
robolab light sensor initialization - set the light on to "false"), it won't
turn on again during running even light was reset to turn again on in the
program. Suggestion?

By the way, the 2.9.4 patch has a bug which fails to get the feedback from
the Ultrasonic sensor. Any suggestion?

Have you tried contacting the people of http://www.ceeo.tufts.edu/ ?
It would appear that they should be able to tell you whether the content will be
back online eventually. Apparently it's just a separate machine in their pool
that may be temporarily offline. Since the site is still actively linked to, my
guess is the current state of things was not entirely on purpose.

Dear Elizabeth, Thank you for your support. I have purchased 2.9.4 and look
forward to using LabView Student Version, if NI lets me have it, with the patch
NI offers to run the RCX & NXT.
My work with the Lego camera is developing on two fronts. The first is to
distill an image into an eight color image and the other is to distill a master
artwork into a number and comparing this number to other master artworks.
Developing the Vision VI is tedious but how else can you do it?
http://130.64.87.22/robolabatceeo/College/tutorials/image_cli/index.htm is an
excellent tutorial. It is just as tedious using NI Vision. Have a Happy Holiday
Season. I am trying to talk my eight-year-old into taking a NXT Kit instead of a
game boy. Programming is so much more rewarding than playing computer games.
