[Roboticsprimer-users] Errors in 01_Introduction Exercise of the Robotics Primer Workbook

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

Hi,
I am trying to use Player to connect the Gumstix to the iRobot Create. I
have compiled and installed Player and transferred the binary file over to
the Gumstix. I am also using the code provided by the Robotics Primer
Workbook. I have compiled their code for the Introduction exercise and it
did generate a binary file called "intro". I read the instructions given by
John Cummins and am not sure if I did the next steps right but, I created a
file called roomba.cfg on the gumstix and ran it using

./player roomba.cfg

This gave me the following error:

./player: ./player: 1: Syntax error: "(" unexpected

Also, I tried running the intro executable file on my desktop using:

./intro client.xml

and it gave me the following error:

./intro: error while loading shared libraries: libroombaClient.so: cannot
open shared object file: No such file or directory

I'm not sure how to fix these errors. Has anyone run into a problem like
this before? Does anyone know how to resolve these errors?
Please let me know,
Thanks,
Adheer

[Roboticsprimer-users] Robostix driver

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

I see that late last year someone else inquired about the availability
of the robostix driver for the Player server, and someone responded with
a promise to post the driver and send an email.  Since I'm just getting
started with the workbook, I missed the ultimate response to that
request.

 

Can anyone tell me where to get that driver?

 

Thanks,

Derek Maddox

Re: [Roboticsprimer-users] Locomotion Section: Exercise 1 Answer links are empty

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

This page:

http://roboticsprimer.sourceforge.net/workbook/Exercise1-Locomotion_and_Odometry%2C_Part_1_iRobot_Create_and_Gumstix

Contains the same solutions for the Gumstix option - if you are using  
the command module, I guess you can't directly compile it, but the  
actual algorithm is fairly trivial and shouldn't take long to convert  
to the other API.

[Roboticsprimer-users] Locomotion Section: Exercise 1 Answer links are empty

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

When I access the Workbook's Locomotion section,  Exercise1-Locomotion
and Odometry, Part 1 - Square Path there are three links depending on
hardware configuration. Each link leads to a page with a code template,
followed by a series of questions.  Sadly, the links to the answers are
empty. For example, on the page

http://roboticsprimer.sourceforge.net/workbook/Exercise1-Locomotion_and_Odometry%2C_Part_1_iRobot_Create_and_Command_Module

there is a list of questions and associated answers (hyperlinked):

However, selecting any "Answer" yields this page:

There is currently no text in this page, you can search for this page
title in other pages or edit this page.

It would be nice to see some answers here, and working code for the
square path, since it is the first exercise. Perhaps these are in the
book? I have not yet purchased it, but plan to soon.

Re: [Roboticsprimer-users] Running behavior_based_control exercises

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

Hi

I test the last SVN code from player-stage, There are some changes:

1. player_pose_t doesn't exist, I replace with player_pose3d_t and
sp.pawith sp.pyaw.
2. Errors related with getbumper finction in execution time, this errors
disappear when i remove all the getbumper related code on GLWindow.cc and
Client.cc

Finally i can  run the behavior examples, but only one robot follow the
algorithm,

Anybody can run this exercise ???


Best Regards

I don't know about your problem, specifically, but it may help to run
the CVS version of player instead of a numbered version. Try that and
see.

[Roboticsprimer-users] Running behavior_based_control exercises

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

Hello everybody Let me introduce my self:

I'm Carlos Camargo I'm teacher in Universidad Nacional de Colombia, i'm
working on a open robotic platform called ECBOT:

http://www.emqbit.com/ecbot

I'm running the behavior_based_control exercises.
When i try to run any exercise, i get a segmentation fault, running the
executable with
gdb i found a problem related with the font size. I just comment this lines
:

client/Global.cc://  font->FaceSize(size);
client/Global.cc://  font->Render(text);

under roboticprimerXXX/player directory

And all works fine...

I'm using player-2.0.5, the new player have some modifications on getpose
function, (this function doesn't exist) it was replaced by getpose2d, and
getpose3d on new player version.

I'm running player with the config file from:
http://roboticsprimer.sourceforge.net/workbook/Group:Group_Howto

and run the exercise executable,

But only one robot executes the algoritms. This is right? If yes, How can i
move the another robots?

Re: [Roboticsprimer-users] iCreate/gumstix

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

You can power the gumstix and other addon boards (wifistix/robostix)  
directly from the Create's batteries. You might need a DC-DC voltage  
converter to step the voltage down (from 12V to 5V).

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

The Robotics Primer Workbook seems to be having a slight problem with
spam appearing on it's websites, i got a quick list of 3 pages that i
know for sure have this issue, and they are as follows:

Re: [Roboticsprimer-users] Player cvs

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

Hi John,

There are actually two commands that you need to enter in order to
download the CVS version of player:

cvs -d:pserver:ano...@pl...:/cvsroot/playerstage
login

cvs -z3 -d:pserver:ano...@pl...:/cvsroot/playerstage
co -P player

I have everything working in my environment, which is:
gentoo linux kernel 2.6.xx (a recent kernel, I just don't have my PC
with me right now)
gcc 4.2.2
player CVS - which I refreshed just a couple days ago
fltk 1.1.7
scons 0.97

I am the only other person who has this working. Not that many people
are using the robotics primer

GDB is a good diagnostic tool. But nothing will help untill you get
player CVS installed.

[Roboticsprimer-users] Player cvs

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

Hi Nate
I'm having no luck downloading the cvs version of player. I enter the command below
copied from the web site in your link. It asks for a password, I press enter as stated in link and it immediately terminates. As far as I can determine nothing has been downloaded. I have never user cvs before, had to download it using synaptic package manager to get this far, so its quite probable I missing a obvious step. 
Any advice?
I have a little time now to try again to get this working but am not really optimistic. It seems a stretch to blame  a segfault in intro on player  which, after all, can only send messages to intro. intro seems to be trying to construct a GUI when it crashes
My version of player is 2.0.4 from 2 May 2007 which is still the version offered at the sourcefourge site. It works fine in a player/stage simulation on one machine.
Perhaps if you would share some information I would feel better about the task.
1) Do you have it working in your environment now? If so please describe your environment.
2) When did you get your version of player? Have you tried it with other versions.?
If so which ones?
3)Has anyone else been successful in getting  this  to work? If so could you put me in touch?
4)Do you have any diagnostic  tools ? Perhaps  a dummy version  of intro  that doesn't  try to talk to  player? So we could at  least  determine  if  player  is the  culprit .

Thanks Nate,
I will download the player SVC as soon as I have some time and can figger out what
command to use. I'm new to SVC so it may take some time.
I'll let you know when I have it.

Okay, I just fixed all the FL include names. But this won't fix your
problem, you really need to install player CVS.

Re: [Roboticsprimer-users] Sorry no improvement

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

Hi John,

I think you have an incorrect version of player installed. Get the CVS
version of Player:
http://sourceforge.net/cvs/?group_id=42445

[Roboticsprimer-users] Just a thought

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

Originally when I made the code in roboticsprimer/player back a few months ago
I had to rename some include files from <filename>.h to <filename>.H this I did by copying the files. Some of these were in Fl something or FL something.
I note that in the gdb backtrace we are in  Fl::flush from ../FL/x.H:125
could this be the source of the error?

Hope this helps

Re: [Roboticsprimer-users] Status?

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

Hi John,

Try getting the SVN version of the workbook, recompile and install the
code in workbook/code/player, then recompile the intro exercise code.
Then run the exercise (after starting player on the gumstix) using:

$ ./intro client.xml

You'll need to change the IP address in client.xml to match the IP on
the gumstix.

Hi John,

I just received my gumstix parts on Friday. I'm busy getting
everything back up and running.

[Roboticsprimer-users] Booting gumstix to Linux w/o serial

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

My gumstix developed the problem of not booting linux at power on if I didn't 
have a terminal connected to the gumstix port. This is a known problem in the 
gumstix comunity. However as the conditions that cause this are the normal conditions
for RoboticsPrimer with player or my work around I thought I'd pass on the solution that worked for me.
I put together one of those little WM2802-ND four position plugs with a 10k resister
between positions 3 and 4 and when I don't have the serial line plugged in I plug this in.
I am very happy I purchased multiples of the connectors required from DIGI-KEY I have already used three of each.
Gumstix documentation refers to other solutions which require cutting some connectors
on the board and connecting some wires and resistors. This was quite disturbing to me  as I  can hardly  see the connectors on the gumstix!
There doesn't seem to be any significant interest in this Create/gumstix option. I shall continue to update this list on my discovery's on a irregular basis.
Nate, any progress report?

[Roboticsprimer-users] Status?

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

Hi Nate,
What is your status on this issue? Have you managed to recreate my problem?
Is there any thing I can do to assist you on this?
I am currently cross-compiling programs for the gumstix, loading them on the gumstix,
which control, via the open interface, the iRobot Create. This procedure works well, and allows one to explore the capabilities of the iRobot Create.
I would still like to get the "Robotics Primer" code to work, any ideas?

John Cummins
