Hi,

I'd like to build an old-style Logo turtle for use with MSW Logo or
some other similar Logo. Actually, I will be helping a pre-teen boy
build the turtle. Basic plan is for:
   - Tri-wheeled turtle device controlled from a Logo package (MSW is
the only one we've tried but another would probably do as well)
   - Turtle<->PC link would be "always on" via a wireless link (no
cables). Cables are fine if wireless isn't possible.
   - Rechargable AA batteries as source of power
   - An offline-mode where once programmed, the turtle can go off and
do things as instructed (this can be a separate turtle if need be).

I am new to both the GoGo board and designing/building robots (but not
to soldering etc). I would be grateful for answers to the following
and, for advice on how to complete my project:

1. Is the GoGo board suitable for this project?.
2. How do I go from the board to a working turtle? (I presume I'm
going to need to read articles and perhaps buy some books too but,
which ones?)
3. Has anyone here done anything similar before?. Is there a web page
that describes such a project?

Cheers,

Micheal

Hi Micheal,

It sounds like an interesting project you are thinking of doing.

>  1. Is the GoGo board suitable for this project?.

The GoGo board can do everything you want except the wireless part. It
requires a serial cable to work during live control. Other tools you
can use include the LEGO Mindstorms kit or the Handy Cricket
(www.handyboard.com/cricket). None have wireless though. But I can
imagine hacking a cheap RC car controller for this purpose.

There are many books out there about how to do basic robotics both
using LEGO and other materials. For example

Robotic Explorations: An Introduction to Engineering Through Design
by Fred G. Martin

>  3. Has anyone here done anything similar before?. Is there a web page

I'm sure this project has been done before using LEGO Mindstorms. I'm
not sure if there is a web page describing it. Here's a site with lots
of links:

http://www.crynwr.com/lego-robotics/

I think a nice start is to get some materials and start to play with
motors and wheels (assuming you have a gogoboard, cricket, or Lego RCX
with which you control the motor). I find Tamiya parts very useful and
cheaper than many other alternatives. This site has a good catalog

Hope this helps,
-Roger.

a. Can you give a quick overview of hacking an RC car controller please?.
b. Which car controller would you recommend hacking for our purposes?.

I've had a quick look at this online. It seems particular to the Lego
toolkit. I'm off to a bookshop later so I can see if it teaches
concepts independent of the Lego stuff.

Thanks.

Thanks, I'll look into the Tamiya parts.

Am I crazy for thinking I can use this as the basis of the turtle.
Just add on the GoGo board somehow and get it to control the wheel and
stuff.

Re: the wall hugging mouse...
Not crazy, Michael, but there are better options to hack.  I'll get back

Which C++ compiler are you using? Since the DLL was compiled with
VC++, I think it tends to work better with the MS compiler.

I use the DLL only with other languages (i.e. VB, Logo) so I don't
have a C++ example.

If you are using C++ as your main development language, it makes more
sense to use the C code directly and skipping the DLL.

I would be very happy if you develop your DLL and the Java module. It
would be even better if you want to share what you did with the
community. I can put your code on the gogo website for others to use.

Dear Fabio,

I tried the 1K resistor in port 1 in the same firmware, and I got a
reading value of 29, and it did not affect any other sensor port (=
1023), Maybe you have a bridge or something making noise on your
board.

Cheers,
Carla

Fabio,

Segui haciendo pruebas, en el puerto 1 puse las siguientes
resistencias y obtuve los siguientes valores:
1k = 29
10 Ohms = 0
33k = 506
100k = 766

nunca afecto a los otros pueros, incluso hice lo mismo con los otros
puerto y siempre obtuve lecturas individuales.

porque no le das una checadita a la soldada? que no existan onexiones
falsas, de ahi en fuera no se me ocurre otra cosa.

saludos
carla

So sorry, Fabio, Oops :.P (this crazy Mexicans!!!)

Here it goes the same thing in English:

I kept on doing some tests, in port 1 I tried the following resistors
and I got the following results.

1k = 29
10 Ohms = 0
33k = 506
100k = 766

any of the resistors in port 1 affected the other ports, I even tried
the same with the other ports and I always got individual values.

My only guess to the problem in your board is that it may have a weak
or faulty soldering connection somewhere.

I can't think in anything else.

Um Abraço,

carla

What an interesting question.  Why don't you try a little experiment and
find out?
I would, but no time today.  I vote "no".  Think of all of the glues
used in
surface-mounted technologies for components and pc boards in
manufacturing.

Susan

Ok, I tried many things because I also am interested on less
soldering. Maybe Paulo, who wrote the guide about making sensors
without soldering can comment on my results.

Super glue by itself is not conductive at all. I tried both: 1) let
it dry at room temperature (kind of cold over here) nor 2) using heat
to dry it. [aluminum--dried glue--aluminum] & [wire—dried glue in a
shrink tube—wire]    (no direct contact between metals)

Gluing to conductive materials (I tried aluminum foil and wire)

Parallel touching and glued: did not have a good connectivity
If the glue fell in between the connection was lost.

So to actually have two things conducting and glued. They have to be
making direct contact between them and the glue has to glue them from
outside, like encapsulating them or making sure that the glue is not
on the point of contact.

A very simple way to test it is to put some super glue in one side of
the wire, and it’s easy to see that as soon as you try to make
contact from the side with glue it stops conducting.

However using super glue seems to be as dangerous as soldering, maybe
the difference is the accessibility, though the connection may not be
as good as soldered ones.

Best regards

carla

Seattle Robotics Society has an online magazine with good articles, the
Encoder.

I seem to remember they have articles on things like soldering and
desoldering, and using a toaster over to demount or mount surface mount
chips...  worth a search and look.

Hello,

I just finish to assembly my gogoboard2.3
It works fine with GoGO Monitor 2.1 (except that the "user led" turn
on with the OFF button and turn off with the ON button).

It doen´t work with the Jackal 0.91.
I´m a beginner in Logo language but I got some links to a tutorial in
this group. I tried to send simple instructions (like beep or turn on
and off the motor) but sometimes only turn on the motor A and
the "run led" blinks.

I read some emails in this group taht this program doesn´t work fine
with 877A chip. Is it fixed ? I´m using 877A chip.

Could the group give a feedback ?

Regards,

Ernesto Maranesi Neto

Congratulations!
Thanks for the UI bug you've found. It will be fixed in the next
release of the program.

The 877A chip will not work with the existing firmware and I believe
this is causing the problem you are having. Unfortunately we have not
fully ported the firmware to the 877A chip. Meanwhile, using the
regular 877 chip is the easiest way out.

Good luck,
-Roger.

Hi all:

I have been doing some tests with motors and lamps. I could see 2 different
cases:

The first case noticed was: If i download the program to gogo board and the
motor is connected to one output, it is not able to run after press the RUN
button and the red LED placed beside the button is kept  on. The motor doesn´t
work.

The second case was: If i download the program to gogo and press the RUN button
before to connect the motor to the output, the red LED blink once and if i
connect the motor as final step it starts to work. The motor works.

I would like to know why gogo board is not able to power the motor up if it is
connected to the output before to press the RUN button?

Best Regards.

Hi Steve,

Which version of the GoGo board are you using? Also, it would be nice
if you can send the code you are trying to run. It is a bit hard to
imagine what may be wrong without more information.

Cheers,
--Roger.

Hi Steve,

Which version of the GoGo board are you using? Also, it would be nice
if you can send the code you are trying to run. It is a bit hard to
imagine what may be wrong without more information.

Cheers,
--Roger.

Okay Steve,

The code explains the behavior of the Run LED in your second case.
Since there is no loop command in the code, the program will execute
and finish in a very short time. So, it is correct that the Run LED
lights up only briefly.

Now, my best guess for why the board doesn't work in your first case
is that you are having power problems. Motors can draw a lot of power
when they are first turned on. In fact, we had a lot of this problem
when I was with you in Costa Rica last year. This problem has been
fixed in the new version of the gogo board (version 2.3). I would
recommend you to use this new version. If you want, I can send you one
board. Please give me your mailing address.

For now, I suspect that if you change the motor and use one that is
rated for 5v, the problem should go away.

Hope this helps,
-Roger.

Hello Roger,

The board works very well now ( I change the uC to 16F877).
I will start my experiences this weekend.
Thanks for your support

Ernesto.
