By "host system", I assume you mean your computer (the correct term  
is "client"). The answer is no. All you need on the client side is  
your own controller.

Yes. The Player server should be running on the Gumstix. If it is not  
there already, you need to follow:

http://playerstage.sourceforge.net/doc/Player-2.0.0/player/ 
group__tutorial__crosscompiling.html

To cross-compile it for the Gumstix.

The only way that I know is to edit /etc/network/interfaces. Answer  
these questions for me:

1. Do you know the IP address for your Gumstix (the static IP that  
you specified, without DHCP).
2. On your Desktop/Laptop, can you ping that IP address?
3. In your client.xml, does the IP address match (1)?

I suspect that that the reason the connection is refused is because  
Player isn't running on the Gumstix.

[Roboticsprimer-users] iCreate/gumstix

[Robotics P. u. h. l. <rob...@li...>]

OK I have connected up a 6 volt supply to the gumstix.
and it works ok
the instructions for changing /etc/network/interfaces do not work.
If I make either of the changes suggested in the intro text the wifi does not work
if I have the line    
iface mwlan0 inet 192.168.0.1 
in interfaces when the gumstix reboots it says somethimg like 192.168.0.1 is not a method
if I do it with the interfaces file as it came 
iface mwlan0 inet dhcp
the ifconfig always, so far, says its address is 192.168.1.104
so I move on to try the intro stuff
when i try 
./intro client.xml
I get connection refused, even after I change the .xml file to my address

A few questions 
1) do I need  to have player running on my host system if what is the commandline
I should use. I have only used Player/Stage as a simulator so far and have no idea
ho to connect it to the robot.
2)should something be running on the gumstix? if so how should I down load it?
3) does any one know how to set up the gumstix so it comes up with a specified address? The instructions on the web site don't work in my case.

If there is anyone out there who has got further than me in the iCreate/Gumstix
set up I would appreciate a reply.

Hi John,

Thanks for the info. And you're going down a very good path. You can
attach that plug to a DC-DC converter
(http://www.dimensionengineering.com/DE-SW050.htm) that is attached to
the 14V output on the Create's bay port.

[Roboticsprimer-users] iCreate/gumstix

[Robotics P. u. h. l. <rob...@li...>]

After some research at gumstix and digikey, gumstix recommends 5v regulated applied to the Robostix and sells a   power supply for 10 or 15 bucks. The plug that goes into the power receptacle on the Robostix is part # CP-012-ND at Digikey  so if any one is starting down this path they might want to add that to their Digikey order.
This may be a waste as the folks at Robotics Primer may have a totally different  way of powering the  gumstix but as it is only 90 cents ...

I shall continue to list my trials and errors on this site as no one has told me not to and they hight help someone to avoid my mistakes.

Hello,

The roombaDev.pc file is automatically generated at compile time.
However, the SConstruct file was setup incorrectly. This has hopefully
been fixed, with the necessary changes on the SVN server. Instructions
on how to download the new code are here:

[Roboticsprimer-users] iCreate/gumstix

[Robotics P. u. h. l. <rob...@li...>]

Update 
In the cons section on for gumstix in Prerequisites it does mention requiring a separate
battery pack as a con for iCreate/gumstix option, But I can not find anything else on
your site about this battery.
Gumstix recommends 5 volts  for their computers.
there appears to be two locations where the power could be connected
does it make a difference?

[Roboticsprimer-users] iCreate/gumstix

[Robotics P. u. h. l. <rob...@li...>]

Now I am trying to do the gumstix wifi set up and have a few questions.

I) the adaptor is sold by acroname has been discontinued I am using their suggested replacement S23-USB-INT-ASSM.
2) the instructions say to plug this cable into the white socket on the Robostix. There is no white socket on my Robostix. I assume you mean the one in the middle labeled GUMSTIX. Is this correct?
3) The instructions next tell me there is something odd on connecting up this and to examine the image carefully. There is no image to examine carefully. when I click on the put image here I am offered a chance to login presumably to upload my image!
4) I try various orientations of the plug but nothing works with kermit. This I now realize is  because I am not supplying any power to the gemstix stack. Is the iCreate supposed to supply power to the stack via the cable I make in the next step? Or do I supply battery power? I assume the latter and will try to find out the requirements from gumstix. It would be nice is you could post info on this?

To avoid confusion I am asking
1) is it alright to use the replacement cable
2) is the socket in question the 4 pin one labeled GUMSTIX
3) Could you please post the image in question, or at least report in greater detail
     what makes this connection unusual.
4) How does the gumstix stack get power, if by battery what voltage and what are the recommended battery packs and connectors. I shall try to find this out from gumstix.

[Roboticsprimer-users] to Jw

[Robotics P. u. h. l. <rob...@li...>]

Jw
Thank you for you response. I had already worked my way to a solution before I 
got your e-mail. I am not being critical but your responses don't tell me what I needed to know
The Library in question was produced by compiling the code in roboticsprimer/player
I know that now, but at the time I did not know if it came for player-2.0.4
or some other package or I was supposed to make it up or what???
My solution of hacking cr8.pc to roombaDev.pc allowed me to move on and discover how the 
system had been set up.
I am very impressed in the quality of the code in robotics-primer
everyone involved has done an outstanding job! 
Given the interest in this subject and the title "robotics PRIMER" (my emphasis) 
I suggest you will shortly be getting a lot of responses for people 
even more ignorant that myself, if that is conceivable.
My oh so humble suggestion is that you turn my catalog of errors
into advice for the un-initiated, I am willing to support this is any way.
You are, of course, permitted to ignore my humble suggestions 

roombaDev.pc is a file required by pkg-config to locate the roomba  
library - in your previous email, you said that you got the error  
when you tried to compile one of the exercises, right? roombaDev.pc  
should have been generated after you compiled the library. Retrace  
your steps - was there an error when you compiled the library that  
tells you roombaDev.pc could not be generated?

player-2.0.4/server/drivers/mixed/irobot/roomba is the driver from  
the Player server - you are looking for the library from the  
workbook. This is the wrong place to look.

As I said before, I'm away from my Linux machine at the moment, and  
cannot tell you exactly where this .pc file is. (it's usually in libs/ 
pkgconfig). If you can't wait, I would suggest that you write your  
own Scons/Makefile to compile the exercise code (assuming that you  
actually have the library and the only thing missing is the .pc file).

[Roboticsprimer-users] success in compiling for iCreate/gumstix

[Robotics P. u. h. l. <rob...@li...>]

Yes! Finally!!

If you are trying to compile the exercise code in the work book here is my recommended process

1) first compile the code in player, do not do anything else until you have  succeeded.
2) In order to do 1 you will need to
     a) down load a lot of packages,
     b) comment out some bad code
     c) change some .H files to .h (there maybe a env variable for this)
3) The last thing the scons in player does is create the roombaDev.pc. I think it needed this at the start. I'm not sure about this my notes are not detailed enough. If you find
it does it will tell you to put the path to roombaDev.pc in the PKG_CONFIG_PATH env variable. If this happens copy the cr8.pc from create to player, re-name it roombaDev.pc and edit it to remove the -lcr8 entry
4) the process is now to run scons install in player, each time it fails fix one of the three things in 2 and try again
5) when scons install in player succeeds, you are ready to go and try compiling exercise  01 

John Cummins

The following are my notes from the experience, some of my errors are obvious in retrospect but they may  help someone in a similar situation 

1) First down load the workbook, they like to hide it on the site but
 with a little diligence you can find it.
2) next you have to install a whole lot of software Imlib, gsl, fltk,
 ftgl, avr,  avrdude , ckermit,  etc.
3) then you have to run "scons  install" in directories create and
 player.
3.5) you may have to be super user to do 3
4) at this time you will probably see messages cant find abc that's
 because the abc software needs to be installed
5) continue doing 4 and 5 until the scons work, or as in my case they
 either work or say you need "roombaDev.pc"
6) go to roboticsprimer-0.1/create and cp cr8.pc roombaDev.pc
7) export PKG_CONFIG_PATH=/home/john/roboticsprimer-0.1/create:$PKG_CONFIG_PATH
8) go to /usr/include/FL 
   cp Fl_Window.H FL_Window.h
   cp Fl.H Fl.h
   (upper case H to lower case h)    
9) in exercises/01-introduction/gumstix  do scons result 
   main.cc:102 error: 'class Client" has no member named stop
10) commented out offending line compiled but link of intro failed

[Roboticsprimer-users] iCreate/gumstix

[Robotics P. u. h. l. <rob...@li...>]

Well, I am proceeding on the assumption that the old roombaDev is now cr8
and have copied cr8.pc to roombaDev.pc and then tried sudo scons install in player.
It goes a lot farther but finaly stops saying

g++ -o behavior_network/libroombaBehavior.so -shared behavior_network/Behavior.os behavior_network/BehaviorNetwork.os behavior_network/ArbiterClient.os -L/home/nate/local/lib -L/usr/local/lib -lcr8 -lplayercore -lltdl -lpthread -lplayerc++ -lplayerc -lm -lplayerxdr -lplayererror

/usr/bin/ld: cannot find -lcr8
collect2: ld returned 1 exit status
scons: *** [behavior_network/libroombaBehavior.so] Error 1
scons: building terminated because of errors.

Any ideas?
Particularly I am looking for information on the source of the elusive roombaDev.pc
and/or what would cause libcr8.a to be incompatable?

I thank everyone who has answered

[Robotics P. u. h. l. <rob...@li...>]

I guess the crux question I have at the moment is does the roombaDev.pc file
come from the workbook, or from player.? If it comes from  the work book, then where is it
(what directory) and how do I create it? I have tried down loading at least twice and it doesn't get down loaded. The only .pc file I get is cr8.pc
Thinking it might come from the Player/Stage stuff I have down loaded that again and some of the stuff in server/drivers/mixed/irobot/roomba looks similar to the group__roombaDev.html file in the documentation that comes with the work book.
If it does come from player how do I generate it as it doesn't get generated by default.

[Roboticsprimer-users] iCreate/gumstix

[Robotics P. u. h. l. <rob...@li...>]

I have found a library called libroomba.la in 
player-2.0.4/server/drivers/mixed/irobot/roomba
could this be the one?
still cant fine roombaDev.pc

Perhaps I did not make my self clear. the only file named anything like roombaDev
on my system is "group__roombadev.html" which is a html file and scons does nothing with it.
Where was "roombaDev.pc" supposed to have come from?
The work book? Player/stage? The other .pc files seem to describe compile options and
library names to use a particular library, probably called libroomba or something similar.
I have searched my system and the internet for anything similar but without luck. synaptic package manager also knows nothing about this.
If you have the source for "roombaDev.pc"  could you send it to me? and the location on your system might help.  I might then be able to search for the actual libraries.

Thank you for you responses

Hi John,

I'm away from my Linux machine right now, so I can't give you a more  
detailed instruction. But based on the error you gave in your  
previous email:

Package roombaDev was not found in the pkg-config search path.
Perhaps you should add the directory containing `roombaDev.pc'
to the PKG_CONFIG_PATH environment variable
No package 'roombaDev' found

The problem is that roombaDev.pc is not within the search path of  
PKG_CONFIG_PATH.

Try:

1. Find where your library and header files are installed (the path  
can be found by opening the SConstruct script).
2. Search that directory, and find where roombaDev.pc is. Record the  
exact path to the directory containing the file. This is usually  
called pkgconfig.
3. Open up your shell's startup script - this is .bashrc or .profile  
or something similar to it, depending on your system.
4. At the end of the file, insert:

export PKG_CONFIG_PATH=/Volumes/Files/Users/jiuguangw/Programs/player/ 
lib/pkgconfig:$PKG_CONFIG_PATH

Replace my directory above with the string you obtained from step #2.  
Make sure you didn't accidently delete something from the script.  
Close all terminals and open up a new one. Try whatever it is you  
were doing before, and see if the error reappears.

To check if you followed these instructions correctly, you can do:

echo $PKG_CONFIG_PATH and see if that directory is indeed listed.

Hope this helps,

Jiuguang

Is there any one there?
are there any instructions on using/setting up this thing?
If anyone else is trying this, this is what I have found out.
1) First down load the workbook, they like to hide it on the site but with a little diligence you can find it.
2) next you have to install a whole lot of software Imlib, gsl, fltk, ftgl, avr,  avrdude , ckermit,  etc.
3) then you have to run "scons  install" in directories create and player.
3.5) you may have to be super user to do 3
4) at this time you will probably see messages cant find abc that's because the abc software needs to be installed
5) continue doing 4 and 5 until the scons work, or as in my case they either work or say you need "roombaDev.pc"
6) Join me in demanding some  info about  roombaDev.pc 

If I am doing anything dumb please enlighten me

Does any one know where the file roombaDev.pc is?

I've been adding packages and discovered I needed to run
"scons install" in directory "create" as su
"sudo scons install"

but in player and exercise/01* I still get an error that it cant find roombaDev.pc

Any advice would be appreatiated

Re: [Roboticsprimer-users] installing the workbook software for iCreate & gumstix

[Robotics P. u. h. l. <rob...@li...>]

John,

I can help you with your problem, but I need a few more details.  What
distribution are you running?  The problem is that you have not
installed imlib2, so it is not found.  Install imlib2, and see if that
works.

[Roboticsprimer-users] installing the workbook software for iCreate & gumstix

[Robotics P. u. h. l. <rob...@li...>]

I hope this is the way to ask for help on setting up to use the workbook
with iCreate and gumstix

I down loaded the work book and made it to examples/01*/gumstix
and ran "scons"
it didn't work but told me how to install "scons"
I did that and it installed
ran scons again which said I needed "roombaDev.pc" in PKG_CONFIG_PATH
could only find a "roombaDev.HTML"
read this mail list and saw that someone else had this problem and you advised going
to player directory and running "scons install"
this I did and it said can't find imlib2-config
in trying scons in other places I get can't find "arv-gcc"

What is wrong? Is there some list of packages etc I need to set up inorder to comple
stuff? I'm not even sure this is the way to use your site at sourceforge. Could you include a simple README file to help people like me.

Re: [Roboticsprimer-users] About Player/Stage for iRobot

[Robotics P. u. h. l. <rob...@li...>]

Stage is a simulator for the roomba.  Player is the software package
for controlling robots and sensors (even in a simulator), that is what
is used in the robotics primer and is what you should use.  I have
heard that it is compatible with uClinux, but I don't know details.  I
would ask on the forums at:

http://playerstage.sourceforge.net
