Christine,

This looks like the same issue you reported a few months ago (right?), 
to which I replied:

There were some corrupted images when we migrated from CVS to SVN, but 
those have been fixed thanks to Debbie Burhans.

You can get those images from:

http://svn.cs.brynmawr.edu/viewvc/pyrobot/trunk/images/

Click each image link, and then (download) saving (as root) into 
/usr/local/pyrobot/images/.

I am having some problems with images in trying to load RLWorld.py .  It may be noteworthy that the image on the curriculum pages dealing with RL also does not appear on the web page.

Thanks for your help on this

Pyrobot Simulator

I've been working on the Vaccuum Cleaner world with the intent of implementing some of the exercises in Russell-norvig 2.8-2.13,  I'm having difficulty having the program end nicely.  There are commands for 'quit' and 'exit' but they don't seem to have an effect - neither closes the gui.  I see the destroy(self) function  in the GUI class in VacuumCleanerWorld.py but I don't know that it is called.  Seems like there should be something in process()   like:  if self.quit ==1:
                                                                                       self.destroy()
or perhaps that variable is monitored somewhere else.

Thanks for any help on this.

Re: Pyrobot simulator: are there any objects that agripper can hold?

Jennifer Kay — 2010-12-01T18:42:39

I must admit that the bouncing is beautiful :-). Alas just this once I'd 
rather they weren't so bouncy.

If I manually steer my robot using the joystick and really get that puck 
as far in as I can, then close the grippers and move forward, it usually 
bounces out of the grippers. Just tried (again manually) to just break 
the first bean and then grab, still no joy.

Re: Pyrobot simulator: are there any objects that agripper can hold?

Douglas S. Blank — 2010-12-01T18:07:23

You know how much time that took to get the pucks to bounce? :)

I though that if you approach the puck straight on, proceed slowly, and 
close the gripper when the first beam is broken, that you can pick them 
up. Is that not the case?

Perhaps we can refine something in the way they interact to be more 
realistic and easier to manipulate?

Pyrobot simulator: are there any objects that agripper can hold?

Jennifer Kay — 2010-12-01T15:32:57

Tried using the pucks, but when the robot moves they bounce out of the 
gripper, even if it's closed. Are there any objects in the simulated 
pyrobot world that the gripper can hold?

Thanks,

Pyro updated to work on Ubuntu 10.10

Douglas S. Blank — 2010-11-18T01:41:52

Due to popular demand, I just updated Pyro a bit to work with Ubuntu
10.10. In 5 steps:

1. sudo apt-get install libjpeg62-dev swig
2. svn co svn.cs.brynmawr.edu/pyrobot/trunk pyrobot
3. cd pyrobot
4. make
5. bin/pyrobot

Does not work with Python 3. You can find more details here:

Re: Pyro 5 install on Windows

Douglas S. Blank — 2010-11-16T15:11:41

Looking at configWin.py, I see that makes a bin\pyrobot.pyw. I guess I'd 
try to run that.

-Doug

Pyro 5 install on Windows

Jennifer Kay — 2010-11-13T15:39:58

 From http://pyrorobotics.org/?page=PyroInstallation I find that I need 
to do:

    svn co http://svn.cs.brynmawr.edu/pyrobot/trunk pyrobot
    cd pyrobot
    python configWin.py

I download a subversion client for windows (after the svn client on 
cygwin gives me an error)
I appear to make it successfully through the above three lines.

Now what? Should I have a pyro executable somewhere?

Thanks,

Re: Pyro with a Pioneer

Nik — 2010-11-10T16:31:28

Hello,

We don't have Pioneers, but we do have Erratics (which are in many ways
similar).  We have Ubuntu (10.04) installed on them along with pyro (you
can use alien to make a deb from the rpm on the web) and player from the
Ubuntu repositories (the package name is robot-player).   (Note that
alien doesn't get the dependencies so you will have to install a couple
of other packages from the Ubuntu repositories: python-imaging-tk,
python-numeric, and python-numpy.)

The only problems are that the compiled version of player included in
the repository doesn't include many of the modules (like the one for a
firewire camera) and you need to make a symbolic link from player to
robot-player in /usr/bin for pyro to be able to find it.

Nik

Re: Pyro with a Pioneer

Douglas S. Blank — 2010-11-09T01:16:29

Hmmm... good questions. Unknown answers. It has been years since we turned
ours on. However, I do know that some people recently have used their
Pioneers with the latest Pyro (out of SVN; [1] to browse, [2] to download)
and I believe that it worked fine. (Player has changed much over the
years, but I think we have a version on the server that works with Pyro).

Pyro with a Pioneer

Jennifer Kay — 2010-11-06T04:31:04

Have pulled out my antique Pioneer and want to use Pyro with it. After 
some serious fussing, I've determined that sometime in the last n years 
the hard drive died. I've got a new hard drive, but I'm not sure what to 
install OS-wise.

Can anyone else tell me what you've used Pyro with on a Pioneer? In 
particular, what version of the OS do you have installed? I'm thinking 
of trying Fedora, but do  I need an ancient version to be compatible 
with Pyro?

Thanks,

- Jennie

Re: Using Pyro with a Hemisson without Bluetooth (more info)

Douglas S. Blank — 2010-10-11T17:32:56

Just for completeness:


Yes. Either way, it is a serial connection.


The server is for simulators, and for those robots that need to start a
server (Player/Stage comes to mind).


I presume that you realized that it is probably something like:

/dev/ttyS0
/dev/ttyUSB0

-Doug

Re: Hemisson Help

Douglas S. Blank — 2010-10-11T17:20:23

Three possibilities:

1) The serial port commands are being eaten. I seem to recall that we had
a hard time trying to get robust serial communication with the Hemisson.

2) You are sending commands so fast that you don't actually see the robot
stop.

3) You are using old code. The CD-ROM code might not be up to date. Also,
computers are much faster than when we wrote that code years ago. Maybe
some timing in the code is off.

There are a few FIXME's in pyrobot/robot/khepera.py... perhaps you can try
tweaking some values?

Hope that helps,

-Doug

Re: Progress,but still some problems using Hemisson over serial port

Douglas S. Blank — 2010-10-11T17:12:17

Yes! :)


This code may be a little odd... 10 times a second (at most) you are
either moving forward, or telling it to briefly not move. I suspect that
the sensor readings have enough noise that it is always moving some. That
is, if you take 10 readings, chances are that at least one (per second) is
going to have enough noise to make it move forward. Eventually, it may be
too close to get an accurate reading.

self is a brain, and there is a convenience method for move there. Compare:

pyrobot/robot/__init__.py
pyrobot/brain/__init__.py
