[Roboticsprimer-users] About Player/Stage for iRobot

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

hi,

i am working in a proyect that use a embedded
operating system (uClinux) in an FPGA, and we are
trying to control the iRobot Create trhough uClinux 
i want to know if is it posible to use the Stage
commands or functions to work in this OS (uClinux)??

thanks for your answers

Re: [Roboticsprimer-users] Development of Create instructions for Robotics Primer

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

Hello,

Sorry for the delay. The next few exercises that will be added involve
reinforcement learning with the Create and the Gumstix. These
exercises might eventually be incorporated with MSRS, but not in the
next few weeks.

Please feel free to contribute to the workbook as you see fit. We have
opened up the workbook as a wiki, so you should be able to create a
new account (link on left side of the screen) and modify anything.
Adding to the code is a little bit more tricky. It will require you to
get a sourceforge account, which is easy, and then have us give you
permission to check code back into the repository.

[Roboticsprimer-users] Development of Create instructions for Robotics Primer

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

Thanks for yesterday's reply.  I am teaching & developing a college course
based on using the Create with Robotics Primer and MSRS.  I've noticed more
instructions for this option are being developed, with new exercises being
posted from just a couple weeks ago.  I am delighted to see this, but would
like to know what other exercises/instructions will be added soon (in the
next 2 weeks) that extend more of the Robotics Primer exercises for use with
Create and MSRS??  The more the merrier and I would like to incorporate
these real time in my course.  Thanks.. A. Gilmore

That link needs to be removed (I'll do it today).  Due to licensing
issues, we cannot post our code using MSRS.  Instead, pseudocode will
be distributed instead, sorry.  I will, in about a week or so, post
instructions for how to create your own project in MSRS and,
generally, the commands you need to use.

Do you get this message when using any MSRS program, or just ones
connected with the RoboticsPrimer?  If it is with any MSRS program,
then I think Microsoft would be the best place to go for support.  My
first thoughts though is that you may be running another instance of
the DSS-server somewhere else.

[Roboticsprimer-users] Installing MSRS files for the IRobot Create

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

On the webpage:
http://roboticsprimer.sourceforge.net/workbook/Introduction::iRobot_Create/Roomba_and_Microsoft_Robotics_Studio

I am attempting to set up Microsoft Robotics studio for use with the Create
robot.  I have installed MSRS v 1.5, but the links on this page
to "copy these files" are not working.  They do not point to files, but only
to a login page I don't seem to be able to access.  Please advise!

Also, I get an error message that says "dssnode was stopped. Check that no
other services are using nodes 50000 and 50001."  Any advice on how to get
around this?

[Roboticsprimer-users] create driver bug

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

I downloaded the Wookbook code from the website and I believe there is a bug on the create driver.
At file roboticsprimer-0.1/create/create.c
function set_speed, line 378

int16_t rightVel = linear_speed + (angular_speed/1e2) * CR8_HALF_AXLE_LENGTH;
int16_t leftVel = linear_speed - (angular_speed/1e2) * CR8_HALF_AXLE_LENGTH;

it should be
int16_t rightVel = linear_speed + (angular_speed/1e3) * CR8_HALF_AXLE_LENGTH;
int16_t leftVel = linear_speed - (angular_speed/1e3) * CR8_HALF_AXLE_LENGTH;

since CR8_HALF_AXLE_LENGTH was defined in mm at create.h.

Thanks,
 Marcos

Re: [Roboticsprimer-users] roombaDev package?

Ahh, I have been using Player CVS, which has GetWatts.

You can comment out this for now, unless you really need to get the
power from the create.

[Roboticsprimer-users] Client has no stop member?

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

On sconsing exercise 01:

client has no member named stop

I've commented it out for now, but I suspect it's bad if the client keeps
going?

Okay, I feel like I'm getting close.

I got a few errors:
client/Client.cc:531: error: 'class PlayerCc::PowerProxy' has no member
named 'GetWatts'

... 'GetJoules'
etc.

I'm just going to put in zeros and see if I can compile.

Re: [Roboticsprimer-users] roombaDev package?

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

Ahh, yes, we need to work on the documentation and name schemes.

In the workbook source, there should be a directory called player. Run
"scons install" in this  directory.

The code in "player" is used to create a nice interface to the real
Player code. This code enables the exercises to focus only on Gumstix
stuff, and not on the Player stuff.

[Roboticsprimer-users] roombaDev package?

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

I trying to scons the first exercise, but I keep running into:

Package roombaDev was not found in the pkg-config search path

Can you give me any hints on finding / installing this package?  Should
player have built this?
